FAQ

Video to MP4 Converter FAQ

Files, privacy, formats and limits.

Yes. It is completely free, with no account and no limit on how many files you process. Downloads carry no watermark.

No. The tool runs inside your browser using WebAssembly. Your file is read into memory on your device, processed there, and the result is saved straight to your downloads.

You can start with MOV, WebM, AVI, MKV, MP4 files. The result is saved as MP4.

There is no fixed limit, but the file has to fit in your browser's memory. Files up to a few hundred megabytes work well on most computers. For very large files, use a desktop browser such as Chrome, Edge or Firefox.

Yes, on modern iPhone and Android browsers. Processing is slower on a phone than on a computer, so shorter files work best there.
