How to Get a YouTube Thumbnail URL (All Resolutions)

The exact i.ytimg.com URL pattern for every YouTube thumbnail size — maxresdefault, sddefault, hqdefault and more — plus how to find a video ID.

2 min read

Every YouTube thumbnail lives at a predictable, public URL on YouTube’s image CDN (i.ytimg.com). Once you know the video ID and the naming pattern, you can construct the direct link to any thumbnail size yourself — or let the thumbnail downloader build and verify them for you.

The URL pattern

YouTube stores each video’s thumbnails at fixed paths built from the 11-character video ID:

https://i.ytimg.com/vi/VIDEO_ID/maxresdefault.jpg   → 1280×720 (HD, "maxres")
https://i.ytimg.com/vi/VIDEO_ID/sddefault.jpg       → 640×480  (SD)
https://i.ytimg.com/vi/VIDEO_ID/hqdefault.jpg       → 480×360  (HQ, always available)
https://i.ytimg.com/vi/VIDEO_ID/mqdefault.jpg       → 320×180  (MQ)
https://i.ytimg.com/vi/VIDEO_ID/default.jpg         → 120×90   (thumbnail strip)

Replace VIDEO_ID with the real ID and open the link — the raw JPEG loads directly, and you can Save image as from there.

How to find the video ID

The video ID is the 11-character code after v= or after the short domain:

  • youtube.com/watch?v=dQw4w9WgXcQ → the ID is dQw4w9WgXcQ
  • youtu.be/dQw4w9WgXcQ → same ID
  • youtube.com/shorts/dQw4w9WgXcQ → Shorts use the same ID scheme

Paste any of those link formats into the downloader or the thumbnail grabber and it extracts the ID automatically — no manual editing needed.

Frame variants (0.jpg, 1.jpg, 2.jpg, 3.jpg)

Alongside the named sizes, YouTube also exposes three auto-generated storyboard frames:

https://i.ytimg.com/vi/VIDEO_ID/1.jpg   (and 2.jpg, 3.jpg)  → 120×90 frames
https://i.ytimg.com/vi/VIDEO_ID/0.jpg                        → same as hqdefault

These are frames sampled from the video, not the creator’s custom thumbnail — useful occasionally, but maxresdefault / hqdefault are what you want for the real cover image.

Why maxresdefault sometimes 404s

maxresdefault.jpg is only generated when the source is large enough — many older or low-resolution uploads never got one, so the URL returns a 404 or a grey placeholder. hqdefault.jpg (480×360) is the guaranteed fallback that exists for every public video. This is exactly why our tools probe each path and only surface the resolutions that actually return a real image — more on that in YouTube thumbnail sizes explained.

If you’d rather not hand-build paths:

  1. Paste the video link into the YouTube thumbnail downloader.
  2. It fetches every valid resolution and shows a preview.
  3. Right-click any preview to Copy image address, or click Download to save the file.

For the single highest-resolution link, the maxresdefault download page targets maxresdefault.jpg directly.

Frequently asked questions

What format are the images? Always JPEG (.jpg), regardless of what the creator uploaded.

Do these URLs work for private videos? No — only publicly served thumbnails are reachable on the CDN.

Is there a 1920×1080 or 4K URL? No. maxresdefault.jpg at 1280×720 is the largest file YouTube serves. See Can you download a 4K YouTube thumbnail?
