Questions
Is this WebM to MP4 converter really free?
Yes. Everyday conversions are free with no account. We offer a paid plan for very large files and high-volume use, but you do not need it for normal work.
What happens to my files after conversion?
They are deleted automatically two hours after upload, and you can delete them sooner from the result screen. We never read their contents and never use them to train anything.
Is there a file size limit?
Uploads are capped at 100 MB per file and 3 files per batch. That covers the overwhelming majority of documents.
Do I need to install anything?
No. It runs entirely in your browser, so it works the same on any operating system.
