Add up to 50 files in any mix of formats, choose the output, and get them back one by one or together in a ZIP. The video never leaves your device. It is read and saved by your browser, so there is no upload, no queue and no copy on a server.
Handy for a folder of old camera clips, a set of screen recordings, or turning a batch of videos into audio files.
How to convert many videos at once
- Choose or drop your videos on the box above. You can add more later.
- Pick the format they should all become.
- Press Convert and wait while they are done one after another.
- Download all as a ZIP, or each file separately.
Mixed formats
Each file takes the fastest route: copied when it can be, re-encoded when it must, and converted with ffmpeg in the page when the browser can’t read it. A file that fails is skipped and the rest carry on.
