YouTube Thumbnail Downloader

Paste any YouTube link and this page gives you the video's thumbnail in every size YouTube stores it in. Unlike the other tools here, nothing is sent to a server — the work happens entirely in your browser.

Below: the four sizes and their exact dimensions, why the largest one sometimes will not load, which link formats are accepted, and what you may and may not do with the image afterwards.

The four sizes, and their exact dimensions

YouTube generates a fixed set of thumbnail files for every video and stores them at predictable addresses. This page builds those addresses from the video ID in your link and offers all four:

HD — 1280 × 720. The full-resolution thumbnail, and the only one worth using for anything you will display large. This is the file the creator uploaded, scaled to 720p.

SD — 640 × 480. A 4:3 crop rather than a scale, so the sides of a widescreen thumbnail are trimmed off. Useful when you specifically need 4:3.

HQ — 480 × 360. The most widely used size across the web. Good for list rows and cards.

MQ — 320 × 180. Small, 16:9, fine for dense lists and previews where the image is decorative.

Why the HD version sometimes will not load

The 1280 × 720 file only exists if the source video was published at 720p or higher. For older uploads, low-resolution videos and some Shorts, YouTube never generated it, and requesting it returns a broken image.

This page handles that: if the HD file is missing, the preview automatically falls back to the 480 × 360 version so you still see something. The HD button will still be offered, because whether that file exists is YouTube's decision and cannot be known before trying it.

If HD gives you a blank or grey image, that video simply has no HD thumbnail. Take the next size down — no tool can produce a file YouTube never created.

Which link formats work

The video ID is extracted from the URL, and five shapes are recognised:

youtube.com/watch?v=… — the standard desktop link.
youtu.be/… — the short share link from the mobile app.
youtube.com/shorts/… — Shorts work exactly like regular videos here.
youtube.com/embed/… — embed URLs from an iframe.
youtube.com/v/… — the legacy format, still found in older pages.

Extra parameters on the end — timestamps, playlist IDs, tracking tags — are ignored, so you can paste a link straight from the share sheet without cleaning it up. What will not work is a channel or playlist URL: those are not videos and have no thumbnail of their own.

Nothing leaves your browser

This tool is the one exception on the site. There is no API call and no server step: your browser reads the ID out of the link, constructs the image addresses, and requests the pictures directly from YouTube. The link you paste is never transmitted to us, because there is nothing here to transmit it to.

A word on what you do next. A thumbnail is part of someone's video and is their work. Using one for reference, commentary, review or study is ordinary practice; republishing it as your own artwork or as the face of unrelated content is not, and is the kind of thing that gets channels struck.

If a button opens the image rather than saving it — which is what happens on most phones — long-press or right-click it and choose Save image.
