Switch a video between MP4, MOV, WebM and MKV. Nothing is uploaded.
About this tool
Convert a video between MP4, MOV, WebM and MKV for free. MP4 is the safest choice when you are not sure, because nearly every phone, computer and website plays it. When your video already suits the new format, converting is quick and the picture stays exactly as it was. Everything happens on your own device, so your video is never uploaded, and there is no account to create and no watermark added to the result. Pick a format below, choose your video and download the converted file.
How to use it
- Choose your video.
- Pick the format you need.
- Press Convert. If the video already suits the new format this takes a moment.
- Download the converted file.
Common questions
Does converting change the quality?
Not when the video already suits the new format: the picture and sound are copied as they are. When the picture has to be made again, a little quality can be lost. The result page says which one applied.
Which format should I pick?
Pick MP4 if you are not sure, because nearly everything plays it. The guide on video formats explains when MOV, WebM or MKV makes more sense.
