If I have a YouTube video URL, is there any way to use PHP and cURL to get the associated thumbnail from the YouTube API?
Each YouTube video has four generated images. They are predictably formatted as follows:
https://img.youtube.com/vi/<insert-youtube-video-id-here>/0.jpg
https://img.youtube.com/vi/<insert-youtube-video-id-here>/1.jpg
https://img.youtube.com/vi/<insert-youtube-video-id-here>/2.jpg
https://img.youtube.com/vi/<insert-youtube-video-id-here>/3.jpg
The first one in the list is a full size image and others are thumbnail images. The default thumbnail image (i.e., one of 1.jpg, 2.jpg, 3.jpg) is:
https://img.youtube.com/vi/<insert-youtube-video-id-here>/default.jpg
For the high quality version of the thumbnail use a URL similar to this:
https://img.youtube.com/vi/<insert-youtube-video-id-here>/hqdefault.jpg
There is also a medium quality version of the thumbnail, using a URL similar to the HQ:
https://img.youtube.com/vi/<insert-youtube-video-id-here>/mqdefault.jpg
For the standard definition version of the thumbnail, use a URL similar to this:
https://img.youtube.com/vi/<insert-youtube-video-id-here>/sddefault.jpg
For the maximum resolution version of the thumbnail use a URL similar to this:
https://img.youtube.com/vi/<insert-youtube-video-id-here>/maxresdefault.jpg
All of the above URLs are available over HTTP too. Additionally, the slightly shorter hostname i3.ytimg.com works in place of img.youtube.com in the example URLs above.
Alternatively, you can use the YouTube Data API (v3) to get thumbnail images.
You can use YouTube Data API to retrieve video thumbnails, caption, description, rating, statistics and more. API version 3 requires a key*. Obtain the key and create a videos: list request:
https://www.googleapis.com/youtube/v3/videos?key=YOUR_API_KEY&part=snippet&id=VIDEO_ID
Example PHP Code
$data = file_get_contents("https://www.googleapis.com/youtube/v3/videos?key=YOUR_API_KEY&part=snippet&id=T0Jqdjbed40");
$json = json_decode($data);
var_dump($json->items[0]->snippet->thumbnails);
Output
object(stdClass)#5 (5) {
["default"]=>
object(stdClass)#6 (3) {
["url"]=>
string(46) "https://i.ytimg.com/vi/T0Jqdjbed40/default.jpg"
["width"]=>
int(120)
["height"]=>
int(90)
}
["medium"]=>

}

string(48) "https://i.ytimg.com/vi/T0Jqdjbed40/sddefault.jpg"

}
}
* Not only that you need a key, you might be asked for billing information depending on the number of API requests you plan to make. However, few thousand requests per day are free.
What Asaph said is right. However, not every YouTube video contains all nine thumbnails. Also, the thumbnails image sizes depends on the video (the numbers below are based on one). There are some thumbnails guaranteed to exist:
Width | Height | URL
------|--------|----
120 | 90 | https://i.ytimg.com/vi/<VIDEO ID>/1.jpg
120 | 90 | https://i.ytimg.com/vi/<VIDEO ID>/2.jpg
120 | 90 | https://i.ytimg.com/vi/<VIDEO ID>/3.jpg
120 | 90 | https://i.ytimg.com/vi/<VIDEO ID>/default.jpg
320 | 180 | https://i.ytimg.com/vi/<VIDEO ID>/mq1.jpg
320 | 180 | https://i.ytimg.com/vi/<VIDEO ID>/mq2.jpg
320 | 180 | https://i.ytimg.com/vi/<VIDEO ID>/mq3.jpg
320 | 180 | https://i.ytimg.com/vi/<VIDEO ID>/mqdefault.jpg
480 | 360 | https://i.ytimg.com/vi/<VIDEO ID>/0.jpg
480 | 360 | https://i.ytimg.com/vi/<VIDEO ID>/hq1.jpg
480 | 360 | https://i.ytimg.com/vi/<VIDEO ID>/hq2.jpg
480 | 360 | https://i.ytimg.com/vi/<VIDEO ID>/hq3.jpg
480 | 360 | https://i.ytimg.com/vi/<VIDEO ID>/hqdefault.jpg
Additionally, the some other thumbnails may or may not exist. Their presence is probably based on whether the video is high-quality.
Width | Height | URL
------|--------|----
640 | 480 | https://i.ytimg.com/vi/<VIDEO ID>/sd1.jpg
640 | 480 | https://i.ytimg.com/vi/<VIDEO ID>/sd2.jpg
640 | 480 | https://i.ytimg.com/vi/<VIDEO ID>/sd3.jpg
640 | 480 | https://i.ytimg.com/vi/<VIDEO ID>/sddefault.jpg
1280 | 720 | https://i.ytimg.com/vi/<VIDEO ID>/hq720.jpg
1920 | 1080 | https://i.ytimg.com/vi/<VIDEO ID>/maxresdefault.jpg
You can find JavaScript and PHP scripts to retrieve thumbnails and other YouTube information in:
You can also use the YouTube Video Information Generator tool to get all the information about a YouTube video by submitting a URL or video id.
In YouTube API V3 we can also use these URLs for obtaining thumbnails... They are classified based on their quality.
https://i1.ytimg.com/vi/<insert-youtube-video-id-here>/default.jpg - default
https://i1.ytimg.com/vi/<insert-youtube-video-id-here>/mqdefault.jpg - medium
https://i1.ytimg.com/vi/<insert-youtube-video-id-here>/hqdefault.jpg - high
https://i1.ytimg.com/vi/<insert-youtube-video-id-here>/sddefault.jpg - standard
And for the maximum resolution..
https://i1.ytimg.com/vi/<insert-youtube-video-id-here>/maxresdefault.jpg
One advantage of these URLs over the URLs in the first answer is that these URLs don t get blocked by firewalls.
If you want to get rid of the "black bars" and do it like YouTube does it, you can use:
https://i.ytimg.com/vi_webp/<video id>/mqdefault.webp
And if you can t use the .webp file extension you can do it like this:
https://i.ytimg.com/vi/<video id>/mqdefault.jpg
Also, if you need the unscaled version, use maxresdefault instead of mqdefault.
Note: I m not sure about the aspect ratio if you re planning to use maxresdefault.
If you want the biggest image from YouTube for a specific video ID, then the URL should be something like this:
http://i3.ytimg.com/vi/SomeVideoIDHere/0.jpg
Using the API, you can pick up the default thumbnail image. Simple code should be something like this:
//Grab the default thumbnail image
$attrs = $media->group->thumbnail[1]->attributes();
$thumbnail = $attrs[ url ];
$thumbnail = substr($thumbnail, 0, -5);
$thumb1 = $thumbnail."default.jpg";
// Grab the third thumbnail image
$thumb2 = $thumbnail."2.jpg";
// Grab the fourth thumbnail image.
$thumb3 = $thumbnail."3.jpg";
// Using simple cURL to save it your server.
// You can extend the cURL below if you want it as fancy, just like
// the rest of the folks here.
$ch = curl_init ("$thumb1");
curl_setopt($ch, CURLOPT_HEADER, 0);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_BINARYTRANSFER,1);
$rawdata = curl_exec($ch);
curl_close($ch);
// Using fwrite to save the above
$fp = fopen("SomeLocationInReferenceToYourScript/AnyNameYouWant.jpg", w );
// Write the file
fwrite($fp, $rawdata);
// And then close it.
fclose($fp);
I made a function to only fetch existing images from YouTube
function youtube_image($id) {
$resolution = array (
maxresdefault ,
sddefault ,
mqdefault ,
hqdefault ,
default
);
for ($x = 0; $x < sizeof($resolution); $x++) {
$url = //img.youtube.com/vi/ . $id . / . $resolution[$x] . .jpg ;
if (get_headers($url)[0] == HTTP/1.0 200 OK ) {
break;
}
}
return $url;
}
YouTube is owned by Google and Google likes to have a reasonable number of images for different screen sizes, hence its images are stored in different sizes. Here is an example of how your thumbnail will be like:
Low quality thumbnail:
http://img.youtube.com/vi/<YouTube_Video_ID_HERE>/sddefault.jpg
Medium quality thumbnail:
http://img.youtube.com/vi/<YouTube_Video_ID_HERE>/mqdefault.jpg
High quality thumbnail:
http://img.youtube.com/vi/<YouTube_Video_ID_HERE>/hqdefault.jpg
Maximum quality thumbnail:
http://img.youtube.com/vi/<YouTube_Video_ID_HERE>/maxresdefault.jpg
You can get the Video Entry which contains the URL to the video s thumbnail. There s example code in the link. Or, if you want to parse XML, there s information here. The XML returned has a media:thumbnail element, which contains the thumbnail s URL.
In YouTube Data API v3, you can get video s thumbnails with the videos->list function. From snippet.thumbnails.(key), you can pick the default, medium or high resolution thumbnail, and get its width, height and URL.
You can also update thumbnails with the thumbnails->set functionality.
For examples, you can check out the YouTube API Samples project. (PHP ones.)
// Get image form video URL
$url = $video[ video_url ];
$urls = parse_url($url);
//Expect the URL to be http://youtu.be/abcd, where abcd is the video ID
if ($urls[ host ] == youtu.be ) :
$imgPath = ltrim($urls[ path ], / );
//Expect the URL to be http://www.youtube.com/embed/abcd
elseif (strpos($urls[ path ], embed ) == 1) :
$imgPath = end(explode( / ,$urls[ path ]));
//Expect the URL to be abcd only
elseif (strpos($url, / ) === false):
$imgPath = $url;
//Expect the URL to be http://www.youtube.com/watch?v=abcd
else :
parse_str($urls[ query ]);
$imgPath = $v;
endif;
YouTube is serving thumbnails from 2 servers. You just need to replace <YouTube_Video_ID_HERE> with your own YouTube video id. These days webP is best format for fast loading of images due to small image size.
https://img.youtube.com https://i.ytimg.com
Examples are with https://i.ytimg.com server just because it’s shorter, no other particular reason. You can use both.

If all you want to do is search YouTube and get associated properties:
Get a public API -- This link gives a good direction
Use below query string. The search query (denoted by q=) in the URL string is stackoverflow for example purposes. YouTube will then send you back a JSON reply where you can then parse for Thumbnail, Snippet, Author, etc.
Another good alternative would be to use the oEmbed API which is supported by YouTube.
You simply add your YouTube URL to the oEmbed URL and you ll receive a JSON including a thumbnail and the HTML code for embedding.
Example:
http://www.youtube.com/oembed?format=json&url=http%3A//youtube.com/watch%3Fv%3DxUeJdWYdMmQ
Would give you:
{
"height":270,
"width":480,
"title":"example video for 2020",
"thumbnail_width":480,
"html":"...",
"thumbnail_height":360,
"version":"1.0",
"provider_name":"YouTube",
"author_url":"https://www.youtube.com/channel/UCza6VSQUzCON- AzlsrOLwaA",
"thumbnail_url":"https://i.ytimg.com/vi/xUeJdWYdMmQ/hqdefault.jpg",
"author_name":"Pokics",
"provider_url":"https://www.youtube.com/",
"type":"video"
}
Read the documentation for more information.
Use:
https://www.googleapis.com/youtube/v3/videoCategories?part=snippet,id&maxResults=100®ionCode=us&key=**Your YouTube ID**
Above is the link. Using that, you can find the YouTube characteristics of videos. After finding characteristics, you can get videos of the selected category. After then you can find selected video images using Asaph s answer.
Try the above approach and you can parse everything from the YouTube API.
I have used YouTube thumbnails in this way:
$url = http://img.youtube.com/vi/ . $youtubeId . /0.jpg ;
$img = dirname(__FILE__) . /youtubeThumbnail_ . $youtubeId . .jpg ;
file_put_contents($img, file_get_contents($url));
Remember YouTube prevents to include images directly from their server.
You can get the video ID from the YouTube video url using parse_url ,parse_str and then insert in to the predictive urls for images. Thanks to YouTube for the predictive URLs
$videoUrl = "https://www.youtube.com/watch?v=8zy7wGbQgfw";
parse_str( parse_url( $videoUrl, PHP_URL_QUERY ), $my_array_of_vars );
$ytID = $my_array_of_vars[ v ]; //gets video ID
print "https://img.youtube.com/vi/$ytID/maxresdefault.jpg";
print "https://img.youtube.com/vi/$ytID/mqdefault.jpg";
print "https://img.youtube.com/vi/$ytID/hqdefault.jpg";
print "https://img.youtube.com/vi/$ytID/sddefault.jpg";
print "https://img.youtube.com/vi/$ytID/default.jpg";
You can use this tool to generate YouTube thumbnails
Just to add/expand on the solutions given, I feel it is necessary to note that, as I had this problem myself, one can actually grab multiple YouTube videos content, in this case, thumbnails, with one HTTP request:
Using a Rest Client, in this case, HTTPFUL, you can do something like this:
<?php
header("Content-type", "application/json");
//download the httpfull.phar file from http://phphttpclient.com
include("httpful.phar");
$youtubeVidIds= array("nL-rk4bgJWU", "__kupr7KQos", "UCSynl4WbLQ", "joPjqEGJGqU", "PBwEBjX3D3Q");
$response = HttpfulRequest::get("https://www.googleapis.com/youtube/v3/videos?key=YourAPIKey4&part=snippet&id=".implode (",",$youtubeVidIds)."")
->send();
print ($response);
?>
YouTube provides us the four generated images for every video through the Data API (v3), for example,
As per this, you need to phrase your URL like this -
www.googleapis.com/youtube/v3/videos?part=snippet&id=`yourVideoId`&key=`yourApiKey`
Now change your video ID and your API key to the your respective video-id and api-key and its response will be a JSON output providing you the four links in the thumbnails of snippet variable (if all are available).
A simple PHP function I created for the YouTube thumbnail and the types are
function get_youtube_thumb($link,$type){
$video_id = explode("?v=", $link);
if (empty($video_id[1])){
$video_id = explode("/v/", $link);
$video_id = explode("&", $video_id[1]);
$video_id = $video_id[0];
}
$thumb_link = "";
if($type == default || $type == hqdefault ||
$type == mqdefault || $type == sddefault ||
$type == maxresdefault ){
$thumb_link = http://img.youtube.com/vi/ .$video_id. / .$type. .jpg ;
}elseif($type == "id"){
$thumb_link = $video_id;
}
return $thumb_link;}
https://i.ytimg.com/vi/<--Video ID-->/default.jpg
Image Size Weight 120px Height 90px
https://i.ytimg.com/vi/<--Video ID-->/mqdefault.jpg
Image Size Weight 320px Height 180px
https://i.ytimg.com/vi/<--Video ID-->/hqdefault.jpg
Image Size Weight 480px Height 360px
https://i.ytimg.com/vi/<--Video ID-->/sddefault.jpg
Image Size Weight 640px Height 480px
https://i.ytimg.com/vi/<--Video ID-->/maxresdefault.jpg
Image Size Weight 1280px Height 720px
If you re using the public API, the best way to do it is using if statements.
If the video is public or unlisted, you set the thumbnail using the URL method. If the video is private you use the API to get the thumbnail.
<?php
if($video_status == unlisted ){
$video_thumbnail = http://img.youtube.com/vi/ .$video_url. /mqdefault.jpg ;
$video_status = <i class="fa fa-lock"></i> Unlisted ;
}
elseif($video_status == public ){
$video_thumbnail = http://img.youtube.com/vi/ .$video_url. /mqdefault.jpg ;
$video_status = <i class="fa fa-eye"></i> Public ;
}
elseif($video_status == private ){
$video_thumbnail = $playlistItem[ snippet ][ thumbnails ][ maxres ][ url ];
$video_status = <i class="fa fa-lock"></i> Private ;
}
I think there is a lot of answers for thumbnail, but I want to add some other URLs to get YouTube thumbnail very easily. I am just taking some text from Asaph s answer. Here are some URLs to get YouTube thumbnails:
https://ytimg.googleusercontent.com/vi/<insert-youtube-video-id-here>/default.jpg
For the high quality version of the thumbnail use a URL similar to this:
https://ytimg.googleusercontent.com/vi/<insert-youtube-video-id-here>/hqdefault.jpg
There is also a medium quality version of the thumbnail, using a URL similar to the high quality:
https://ytimg.googleusercontent.com/vi/<insert-youtube-video-id-here>/mqdefault.jpg
For the standard definition version of the thumbnail, use a URL similar to this:
https://ytimg.googleusercontent.com/vi/<insert-youtube-video-id-here>/sddefault.jpg
For the maximum resolution version of the thumbnail use a URL similar to this:
https://ytimg.googleusercontent.com/vi/<insert-youtube-video-id-here>/maxresdefault.jpg
Although there are already many answers, but for new visitors I will leave mine with two options for obtaining a thumbnail.
$api_key = YOUR_API_KEY ;
$youtube_video_id = jNQXAC9IVRw ;
$curl = curl_init();
curl_setopt_array($curl, array(
CURLOPT_URL => https://www.googleapis.com/youtube/v3/videos?key= .$api_key. &part=snippet&id= .$youtube_video_id,
CURLOPT_RETURNTRANSFER => true,
CURLOPT_ENCODING => ,
CURLOPT_MAXREDIRS => 10,
CURLOPT_TIMEOUT => 0,
CURLOPT_FOLLOWLOCATION => true,
CURLOPT_HTTP_VERSION => CURL_HTTP_VERSION_1_1,
CURLOPT_CUSTOMREQUEST => GET ,
));
$response = curl_exec($curl);
curl_close($curl);
$response = json_decode($response,true);
print_r($response); // result with video information and thumbnails
In addition to the API, thumbnails can be obtained via a direct link, like this:
https://i.ytimg.com/vi/jNQXAC9IVRw/hqdefault.jpg
Let s consider this option in detail:
https://i.ytimg.com/vi/<YOUTUBE_VIDEO_ID>/<SIZE_VALUE>.jpg
Where:
YOUTUBE_VIDEO_ID : Your video IDSIZE_VALUE : Thumbnail size. The variable can contain such values: default, mqdefault, hqdefault, sddefault, maxresdefault$youtube_video_id = jNQXAC9IVRw ;
$size = hqdefault ;
$curl = curl_init();
curl_setopt_array($curl, array(
CURLOPT_URL => "https://i.ytimg.com/vi/{$youtube_video_id}/{$size}.jpg",
CURLOPT_RETURNTRANSFER => true,
CURLOPT_ENCODING => ,
CURLOPT_MAXREDIRS => 10,
CURLOPT_TIMEOUT => 0,
CURLOPT_FOLLOWLOCATION => true,
CURLOPT_HTTP_VERSION => CURL_HTTP_VERSION_1_1,
CURLOPT_CUSTOMREQUEST => GET ,
));
$response = curl_exec($curl);
curl_close($curl);
// Write the file
$handle = fopen("image/filename.jpg", w ); // set your directory and filename
fwrite($handle, $response);
fclose($handle);
Method 1:
You can find all information for a YouTube video with a JSON page which has even "thumbnail_url", http://www.youtube.com/oembed?format=json&url={your video URL goes here}
Like final URL look + PHP test code
$data = file_get_contents("https://www.youtube.com/oembed?format=json&url=https://www.youtube.com/watch?v=_7s-6V_0nwA");
$json = json_decode($data);

Here s the top answer optimized for manual use. The video ID token without separators enables selecting with a double click.
Each YouTube video has four generated images. They are predictably formatted as follows:
https://img.youtube.com/vi/YOUTUBEVIDEOID/0.jpg
https://img.youtube.com/vi/YOUTUBEVIDEOID/1.jpg
https://img.youtube.com/vi/YOUTUBEVIDEOID/2.jpg
https://img.youtube.com/vi/YOUTUBEVIDEOID/3.jpg
The first one in the list is a full size image and others are thumbnail images. The default thumbnail image (ie. one of 1.jpg, 2.jpg, 3.jpg) is:
https://img.youtube.com/vi/YOUTUBEVIDEOID/default.jpg
For the high quality version of the thumbnail use a URL similar to this:
https://img.youtube.com/vi/YOUTUBEVIDEOID/hqdefault.jpg
There is also a medium quality version of the thumbnail, using a URL similar to the HQ:
https://img.youtube.com/vi/YOUTUBEVIDEOID/mqdefault.jpg
For the standard definition version of the thumbnail, use a URL similar to this:
https://img.youtube.com/vi/YOUTUBEVIDEOID/sddefault.jpg
For the maximum resolution version of the thumbnail use a URL similar to this:
https://img.youtube.com/vi/YOUTUBEVIDEOID/maxresdefault.jpg
All of the above URLs are available over HTTP too. Additionally, the slightly shorter hostname i3.ytimg.com works in place of img.youtube.com in the example URLs above.
Alternatively, you can use the YouTube Data API (v3) to get thumbnail images.
This is my client-side-only no-API-key-required solution.
YouTube.parse( https://www.youtube.com/watch?v=P3DGwyl0mJQ ).then(_ => console.log(_))
The code:
import { parseURL, parseQueryString } from ./url
import { getImageSize } from ./image
const PICTURE_SIZE_NAMES = [
// 1280 x 720.
// HD aspect ratio.
maxresdefault ,
// 629 x 472.
// non-HD aspect ratio.
sddefault ,
// For really old videos not having `maxresdefault`/`sddefault`.
hqdefault
]
// - Supported YouTube URL formats:
// - http://www.youtube.com/watch?v=My2FRPA3Gf8
// - http://youtu.be/My2FRPA3Gf8
export default
{
parse: async function(url)
{
// Get video ID.
let id
const location = parseURL(url)
if (location.hostname === www.youtube.com ) {
if (location.search) {
const query = parseQueryString(location.search.slice( / .length))
id = query.v
}
} else if (location.hostname === youtu.be ) {
id = location.pathname.slice( / .length)
}
if (id) {
return {
source: {
provider: YouTube ,
id
},
picture: await this.getPicture(id)
}
}
},
getPicture: async (id) => {
for (const sizeName of PICTURE_SIZE_NAMES) {
try {
const url = getPictureSizeURL(id, sizeName)
return {
type: image/jpeg ,
sizes: [{
url,
...(await getImageSize(url))
}]
}
} catch (error) {
console.error(error)
}
}
throw new Error(`No picture found for YouTube video ${id}`)
},
getEmbeddedVideoURL(id, options = {}) {
return `https://www.youtube.com/embed/${id}`
}
}
const getPictureSizeURL = (id, sizeName) => `https://img.youtube.com/vi/${id}/${sizeName}.jpg`
Utility image.js:
// Gets image size.
// Returns a `Promise`.
function getImageSize(url)
{
return new Promise((resolve, reject) =>
{
const image = new Image()
image.onload = () => resolve({ width: image.width, height: image.height })
image.onerror = reject
image.src = url
})
}
Utility url.js:
// Only on client side.
export function parseURL(url)
{
const link = document.createElement( a )
link.href = url
return link
}
export function parseQueryString(queryString)
{
return queryString.split( & ).reduce((query, part) =>
{
const [key, value] = part.split( = )
query[decodeURIComponent(key)] = decodeURIComponent(value)
return query
},
{})
}
Save this code in empty.php file and test it.
<img src="<?php echo youtube_img_src( 9bZkp7q19f0 , high );?>" />
<?php
// Get a YOUTUBE video thumb image s source url for IMG tag "src" attribute:
// $ID = YouYube video ID (string)
// $size = string (default, medium, high or standard)
function youtube_img_src ($ID = null, $size = default ) {
switch ($size) {
case medium :
$size = mqdefault ;
break;
case high :
$size = hqdefault ;
break;
case standard :
$size = sddefault ;
break;
default:
$size = default ;
break;
}
if ($ID) {
return sprintf( https://img.youtube.com/vi/%s/%s.jpg , $ID, $size);
}
return https://img.youtube.com/vi/ERROR/1.jpg ;
}
There are some thumbnails guaranteed to exist:
Width | Height | URL
------|--------|----
120 | 90 | https://i.ytimg.com/vi/<VIDEO ID>/1.jpg
120 | 90 | https://i.ytimg.com/vi/<VIDEO ID>/2.jpg
120 | 90 | https://i.ytimg.com/vi/<VIDEO ID>/3.jpg

Thanks.
Here is a simple function I created for getting the thumbnails. It is easy to understand and use.
$link is the YouTube link copied exactly as it is in the browser, for example, https://www.youtube.com/watch?v=BQ0mxQXmLsk
function get_youtube_thumb($link){
$new = str_replace( https://www.youtube.com/watch?v= , , $link);
$thumbnail = https://img.youtube.com/vi/ . $new . /0.jpg ;
return $thumbnail;
}
