A small tool with one job.

Where it started

Framecatch began as a shortcut for checking how a thumbnail actually looks once YouTube compresses and crops it — the gap between the 1280×720 file a designer exports and the 320×180 preview most viewers scroll past is bigger than it seems. Instead of digging through browser dev tools every time, we built a page that does it in one paste.

Who it's for

• Video editors and thumbnail designers checking how artwork holds up at smaller sizes before publishing.
• Students and researchers who need a still reference image from a public video for a project or presentation.
• Writers and bloggers previewing how a linked video will look when embedded.
• Anyone who just wants a quick copy of a thumbnail without digging through page source code.

How it actually works

YouTube stores thumbnail images at a predictable address for every public video, built from the video's own ID. Framecatch reads the link you paste, pulls out that ID entirely inside your browser, and requests each available size directly from YouTube's image servers. Nothing is uploaded, re-hosted, or processed on a server we control — the tool is really just a fast, well-labeled shortcut to files that are already public.

What Framecatch won't do

It won't download the video itself, bypass private or unlisted video restrictions, or store a copy of anything you look up. It's built strictly around publicly available thumbnail images, and it respects that those images belong to their original creators.
