Frequently Asked Questions
Why convert WEBM to MP4?
WEBM works well in browsers, but video editors, iPhones and many devices don't accept it. MP4 is the most widely supported video format there is.
Is it safe to convert WEBM videos online?
Yes. Unlike traditional online converters, this tool never uploads your files. The conversion runs entirely inside your browser using WebAssembly, so WEBM 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.
