Frequently asked questions

Does it work in all browsers?

It works in current versions of Chrome, Edge, Firefox, and Safari that support WebCodecs. Processing uses your device’s video acceleration, so it’s usually faster than uploading the file to a website.

Is there a file size or video length limit?

We don’t set a limit. Very large files (several GB) depend on your device’s memory; on phones, we recommend videos that are a few minutes long or less.

Are my files uploaded to a server?

No. This tool runs entirely in your browser: your file is read and processed on your device, and not a single byte is sent over the internet. You can even disconnect from the internet after the page loads.

Is it really free? Is there a daily limit?

It's free with no daily limits. Processing happens on your device, so there's no per-use cost and no need to limit you.

Does it work on phones?

Yes. The site works in any modern browser on Android, iPhone, Windows, Mac, and Linux—no installation needed.
