Video Converter
Change any video to MP4, MOV, WebM or MKV, and make it smaller if you like. Several at once.
How to convert a video

MP4, MOV, WebM, MKV, AVI and more, as many as you like.
- Pick a format
MP4 is the safe choice for everything. Make it smaller with Size if you need to.

Questions
Is it really free, with no sign-up and no watermark?
Yes, completely. There's no sign-up, no login, no watermark and no daily limit: just open the page and start. It works in your browser on any computer, phone or tablet with nothing to install, and your files are never uploaded. Everything happens on your device.
How do I convert MOV to MP4?
Choose the MOV file (from an iPhone, for example), keep MP4 selected and press Convert. If the video is already H.264 it's just repackaged, which is quick and loses no quality.
How do I convert WebM or MKV to MP4?
The same way: choose the file, pick MP4 and Convert. Videos in other formats are re-made in H.264, which every device plays.
Why is it slow on some videos?
When the picture has to be re-made (a new size, or a format the new file can't hold) every frame is encoded on your device. A computer is much faster than a phone. Keep the tab open until it's done.
Is there a watermark or a size limit?
No watermark. Big videos work as long as your device has enough memory. For very long 4K videos, use a computer.
Are my videos uploaded?
No. They're converted in your browser and never leave your device.
