Frequently asked questions
Is it really free?
Yes. No sign-up, no watermark and no limit on how many files you convert. The site is paid for by ads.
Is my video uploaded anywhere?
No. The conversion runs inside your browser, on your own computer. The file never leaves your device, not even to our servers.
Is there a file size limit?
There is no upload limit, because nothing is uploaded. Very large files (several GB) depend on your computer's memory.
Will I lose quality?
When the video is already H.264, it is copied without re-encoding, so nothing is lost. Otherwise it is re-encoded; keep Quality on High for the best result.
Which browsers work?
Google Chrome and Microsoft Edge on a computer work best. They have the video encoders the converter needs.
