Frequently Asked Questions
Which formats can I convert to MP4?
MKV, MOV, AVI, WEBM, M4V, MPG, 3GP and most other common video files. If your file plays in a modern media player, chances are it can be converted here.
Will converting video to MP4 lose quality?
When the underlying codecs are compatible, the converter repackages the streams without re-encoding, which is lossless and near-instant. When re-encoding is required, it uses high-quality settings that keep the output visually identical to the source.
Is it safe to convert videos online?
Yes. Unlike traditional online converters, this tool never uploads your files. The conversion runs entirely inside your browser using WebAssembly, so videos never leave your device — you can even disconnect from the internet after the page loads and it still works.
Is there a file size limit?
Files up to about 1.5 GB are supported. Because processing happens in your browser's memory rather than on a server, very large files depend on your device's available RAM.
