Which formats does it convert between?

MP4, WebM, MOV, AVI and MKV, in any direction between them.

Does converting formats reduce video quality?

There's some quality tradeoff inherent to re-encoding into a different format, though at reasonable settings the difference is generally not noticeable.

Which format should I choose if I'm not sure?

MP4 is the most broadly compatible choice across devices and platforms if you don't have a specific requirement pointing you to another format.

Does Video Format Converter upload my files to a server?

No. Video Format Converter runs entirely in your browser using on-device processing, your files never leave your device.

About this tool

Not every device, platform or piece of software accepts every video format — MP4, WebM, MOV, AVI and MKV all have different levels of compatibility, and a video in the wrong format simply won't open where you need it to. This tool converts a video between these formats, giving you the file in whichever format your destination actually supports.
