Frequently asked questions
Is the quality preserved?
Yes. When the video is already H.264, HEVC, VP9 or AV1, it is simply copied into an MP4 file without re-encoding: instant and completely lossless.
Why convert an iPhone MOV?
Some websites, programs and TVs refuse MOV files. The MP4 holds the same video in a format accepted everywhere.
What about AVI files?
AVI is not supported yet. Supported formats are MOV, WEBM, MKV and MP4.
Are my files uploaded to a server?
No. Processing happens entirely in your browser, on your device. No file is uploaded or stored. You can check: once the page has loaded, disconnect from the internet and the tool still works.
Is there a file size or number limit?
No. Since nothing goes through our servers, there is no quota. The only limit is your device's memory: a computer handles very large files more easily than a phone.
Is it really free?
Yes. No sign-up, no watermark added to your documents and no usage limit.
