Resolution guide
YouTube generates several fixed thumbnail sizes per upload — not every video has all of them. Full breakdown on the size guide page.
| Label | File | Size | Notes |
|---|---|---|---|
| Max HD | maxresdefault.jpg | 1280 × 720 | Only exists if the source was uploaded at 720p or higher |
| Standard | sddefault.jpg | 640 × 480 | Reliable fallback for most uploads |
| High Quality | hqdefault.jpg | 480 × 360 | Always available, used by embeds |
| Medium | mqdefault.jpg | 320 × 180 | Used in search result grids |
| Default | default.jpg | 120 × 90 | Smallest, used in old players |
Frequently asked
Is it legal to download YouTube thumbnails?
Thumbnails are hosted publicly by YouTube and viewing them requires no login. Downloading one for personal reference, commentary, or fair-use purposes is generally fine. Reusing someone else's thumbnail artwork commercially without permission can raise copyright issues, since the creator owns the image.
Why is there no Max HD (1280×720) option for some videos?
The maxresdefault file only exists if the original uploader provided a source video at 720p or higher. Older or low-resolution uploads may only have hqdefault (480×360) or smaller available.
What image format are YouTube thumbnails in?
YouTube thumbnails are served as standard JPG files, so they open and save correctly on any device without extra conversion.
Does GrabThumb store or upload my videos?
No. The tool only reads the video ID from the link you paste and requests the thumbnail image directly from YouTube's own servers. Nothing is uploaded, stored, or processed on any server.
