Convert JFIF to JPG
JFIF files are byte-for-byte JPEG images — but half the internet's software rejects the .jfif extension. This gives you a proper .jpg that Inkscape, Instagram, and every other tool will happily open. Downloaded from Pinterest? Chrome on Windows? This is the fix.
How it works

.jfiffile (or any image) onto the page. - The JPG output preset is already selected — hit Convert Now.
- Download the result. The whole conversion ran in your browser via WebCodecs or FFmpeg.wasm. No file left your device.

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.
