About this tool
Convert a video into a different format and codec without installing anything. Pick MP4 (H.264) for maximum compatibility, WebM (VP9) for the web, or MKV, MOV and AVI for other workflows. Your file is processed entirely on your device and is never uploaded.
Frequently asked questions
Which format should I choose?
MP4 (H.264) plays almost everywhere and is the safest choice. WebM (VP9) is great for the web, while MKV, MOV and AVI suit specific editors and devices.
Is there a file size limit?
There is no fixed limit, but everything runs in your browser's memory. Very large or long videos take longer and use more RAM, so shorter clips convert fastest.
Are my videos uploaded anywhere?
No. Conversion happens locally on your device, so your video never leaves your computer.
