Video Studio

Trim a video, cut out the boring bits, make it small enough to send on WhatsApp, turn it into an MP4, or take out the sound as an MP3. Everything happens on your own device: nothing is uploaded.

MP4, MOV (iPhone) and WebM work best.

How to use it

Video processing uses Mediabunny (MPL-2.0) and MP3 saving uses LAME (LGPL, via lamejs).
