Common questions

Is my video really not uploaded?
Correct. Your file is processed privately on your own device and never leaves it, there's nothing to upload, store, or delete. It even keeps working offline once the page has loaded.
Do I need an account?
No. Every tool is free to use with no sign-up and no watermark.
What's the catch with file size?
Very large files on low-memory phones can hit a limit. On a desktop you can comfortably handle a few hundred MB.
Which devices work?
Any modern device with an up-to-date browser, recent Chrome, Edge, Firefox and Safari on desktop or mobile all work.

Edit your video without giving it away.

Free, private, and instant, nothing to upload.
