YouTube Thumbnail Grabber pulls the standard thumbnail image sizes for a public video from a watch URL or bare video ID.
Paste a URL such as https://www.youtube.com/watch?v=... or enter the ID, then click Grab thumbnails. The script parses the ID and lists common size names including maxresdefault, sddefault, hqdefault, mqdefault, and default so you can open or save the variants YouTube already hosts. Missing maxres images are common when a video never received a custom high-res still.
Only use thumbnails you have rights to reuse.

- Fall back to hqdefault when maxres 404s on an older upload.
- Collect default and mq sizes to see how soft crops look in small UI slots.
- Parse an ID from a playlist share link after cleaning to the watch URL if needed.
Tips and limits
- Private or unlisted access rules still apply in practice; respect channel ownership.
- Not every video has maxresdefault; a broken image usually means that size was never generated.
- Thumbnails are JPEG assets hosted by YouTube; this tool does not invent new art.
- Hotlinking policies and rights still matter when you republish.
- For redesigns, start from the highest available size you can legally use.

What data leaves my browser?
The page parses the ID locally, then your browser requests thumbnail images from YouTube CDN URLs. BeeForge does not proxy the image bytes for this tool.
Mobile use?
Yes. Long-press images to save on many phones.
Grab shows an error.
Confirm the URL contains a valid video ID and is not a channel URL alone.
