About YTThumb

YTThumb is a small set of YouTube utilities built around one observation: most thumbnail tools print a URL and hope for the best. Ask for the 1280×720 cover of a video whose creator never uploaded artwork that large, and you get either an error or — worse — a 120×90 grey square that looks like a download succeeded. Every tool here probes first and labels what is missing.

The same idea runs through the metadata tools. YouTube still stores tags, full descriptions, video IDs and channel IDs, but the interface has hidden all four behind a handle, a collapsed paragraph or a different URL shape. These pages return the plain values as copyable text, without an API key and without an account.

What we deliberately do not build

No video downloading. Not as a paid tier, not as a hidden tab. YTThumb requests images and page metadata only; video and audio files are never fetched, proxied, converted or stored. That is a design decision, not an oversight — plenty of tools do that job, and we would rather keep this one clean.

How the tools run

Everything works in your browser. The single server-side piece is a read-only proxy that fetches an image or a public page on your behalf — needed because browsers block cross-site requests to YouTube's CDN. It stores nothing: no logs of which videos you looked at, no accounts, no history.

Credits and ownership

Thumbnails, titles, descriptions and tags belong to the creators who made them. YTThumb is an independent project, not affiliated with, endorsed by or sponsored by YouTube or Google. If you are a creator and want a page changed or removed, write to support@ytthumb.best and it will be handled.
