Frequently asked questions

Which formats are supported?

Input: MP4, MOV, WebM and MKV. Output: MP4, WebM and GIF, plus audio as MP3, WAV, M4A, OGG and FLAC.

Why does it take a while?

Video is re-encoded right on your device with the browser's built-in codecs. A minute of video takes from tens of seconds to a few minutes; MOV and MKV with H.264 are repackaged into MP4 in seconds.

How does it work?

Pick files or drop them onto the page, then choose a format for each file — or one for all of them. Download the results one by one or as a single ZIP.

Are my files uploaded?

No. The converter runs right in your browser: files are processed on your device and never sent anywhere.
