ClipFit

Compress, convert, trim, crop & more — entirely in your browser. Your file is never uploaded.

Getting a video under a size limit

Almost every video compression job starts with a number someone else chose: Discord's attachment cap, an email limit, a form that refuses anything over a few megabytes. The question is never "compress this a bit" — it is "make this fit under 25 MB without it looking terrible".

ClipFit does that inside the browser tab, using the WebCodecs engine your browser already ships for video playback. There is no upload, which matters more for video than for anything else: a large file would otherwise mean a long wait before the work even starts, and a copy of your footage sitting on someone else's server.

What you can do

No watermark and no sign-up — including on the output, which is where most free online video tools collect their fee.

Frequently asked questions

Is my video uploaded?

No. Encoding runs on your own device, which is also why it stays fast on large files — there is no upload to sit through first.

Is there a size cap?

No fixed cap. The practical ceiling is your device's memory, since the file is processed locally.

Which browsers work?

ClipFit needs WebCodecs, so an up-to-date Chrome, Edge, Firefox or Safari. It tells you plainly if your browser cannot run it.
