About this Video Converter tool

Different devices and apps expect different video formats. A WebM screen recording may not open in a video editor, an MKV file may not play on a phone, and a website may need WebM.

This converter rewraps the video into the new format whenever the codecs allow it, which is almost instant and keeps the exact original quality. Only when it's really needed does it re-encode the picture.

Frequently asked questions

Which format should I choose?

MP4 plays almost everywhere: phones, TVs, Windows, Mac and websites. Choose WebM for web pages and MOV for Apple editing apps.

Will I lose quality?

Usually not. If the video can be copied into the new format, the picture is untouched. When re-encoding is needed, high quality settings are used.

Can it convert AVI or WMV?

Not yet. Supported inputs are MP4, MOV, M4V, WebM, MKV and 3GP.

Is my video uploaded?

No. The whole job runs inside your browser using your device's built-in video encoder, so the video never leaves your device.
