Free Video Tools That Run in Your Browser

Edit, compress, caption and test your video without uploading it anywhere. Every tool below runs on your own device, so even large files stay private and there is no sign up.

Video Editor

Trim, cut, merge and crop clips on a timeline, add titles and text, then export an MP4. Untouched footage is copied without re-encoding, so there is no quality loss.

Nothing is uploaded

The editor, compressor and caption generator read your file straight from your disk. It never reaches a server.

No sign up, no watermark

Open a tool and start working. There is no account, no queue and nothing stamped on your video.

Works with large files

Because the work happens on your device, there is no upload limit to wait for and nothing to pay for.

Also free on VdoCipher
