Extract a JPG thumbnail from MP4

How it works

1. Drop a .mp4 file (or any video) onto the page.
2. The JPG output preset is already selected — hit Convert Now.
3. Download the result. The whole conversion ran in your browser via WebCodecs or FFmpeg.wasm. No file left your device.

Why convert MP4 to JPG?

Grab a frame from your MP4 video and save it as a JPEG. Pick the exact moment with the built-in scrubber. Great for making video thumbnails for YouTube, blog headers, or social previews.

Is my file uploaded anywhere?

No. poqpoq is a static site — the page you're looking at is a bunch of JavaScript your browser downloaded once. It runs entirely on your device. There is no upload endpoint. When you open your browser's Network tab during a conversion, you'll see zero requests going out.
