Video Format Converter
Move a clip between MP4, WebM, MOV, AVI, MKV and GIF when a player or upload form refuses the file you have.
◆ VIDEO TOOLS
Most video work is not editing. It is getting a file into the right format, cutting out the part that matters and making sure people can follow it. These are the Bubixo tools for exactly that.

Choosing between them
Convert first if the file will not open anywhere, then trim it down to what matters, and only then add subtitles, captions or narration. Doing it the other way round means redoing work every time the source file changes.
Each tool runs in the browser and hands back a file you can download. Start with whichever problem is in front of you.
