Convert Video Format

Convert a video between MP4, WebM and MOV right in your browser. Pick the format you need and download the result, with no watermark and nothing uploaded to a server.

A video converter changes a clip between MP4, WebM and MOV without uploading it anywhere. Add your file, pick the output format, and download the result, so it works to convert a video format online, turn MP4 to WebM for the web, or switch to MOV for Apple editing. MP4 plays almost everywhere, while WebM makes a smaller file for a website. It all happens in your browser with no watermark.

Frequently asked questions

Which format should I choose?
MP4 is the safest choice and plays on almost every device, app and social platform. WebM produces a smaller file and is ideal for embedding on a website. MOV is handy when you are working inside Apple software like iMovie or Final Cut. When in doubt, MP4.
How do I convert MP4 to WebM?
Add your MP4, choose WebM as the output format, and convert. WebM uses modern compression, so the file is usually smaller than the MP4 at a similar quality, which is why it is popular for web video.
Does converting lose quality?
Any format change re-encodes the video, so there is a small quality cost, the same as with any converter. The settings here are tuned to keep that loss low, so for normal viewing the difference is hard to notice.
