Convert a video to MP4, WebM or MOV

Turn a video into a format your phone, editor or website will accept. The conversion runs on your own device, so the video is never uploaded.

How to convert a video to another format

STEP 1

Add the video

MP4, MOV, WebM, MKV and most others open.

STEP 2

Pick the format and quality

MP4 is the safe choice. Use WebM for websites and MOV for Apple apps and some editors.

STEP 3

Convert and save

The whole video is re-encoded in your browser, with a progress bar and a Stop button.

Which format should you pick?

MP4 with H.264 video and AAC sound plays almost everywhere: phones, TVs, browsers, messaging apps and every editor. If you are not sure, choose MP4.

WebM is for putting video on a website. It is saved here with the older VP8 video and Vorbis sound, which every browser plays, because they encode reliably inside a browser. MOV is the container Apple uses, and it suits editing programs on a Mac. Here it holds the same H.264 video as an MP4.

Converting means the video is encoded again, which costs a small amount of quality each time. Choose Best quality if the result matters, and convert from the original rather than from a copy that has already been converted.

Questions

Is my file uploaded anywhere?

No. The work happens inside this tab, on your own machine. Open your browser's network tab while you use the tool, there is no request carrying your file.

Is there a file size limit?

None set by us. Very large files are limited only by your device's memory, and we warn you before that becomes a problem.

Do I need an account?

No, and there is no daily limit either. There is nothing to sign up for.

Does converting lower the quality?

A little, because the video is encoded again. Best quality keeps the loss very small. It is better to convert from the original than from a copy.

Can it make an MP3 or a GIF?

Not here. Use the Video to MP3 tool for the sound and the Video to GIF tool for a short looping clip.

Why is it slow?

It runs inside your browser, not on a fast server. A progress bar shows how far along it is and you can stop it at any time.
