When to use WebM
WebM files are often smaller than MP4 at the same quality and play in every modern browser. Use them for background and product videos on websites.
How to use it
- Drop your MP4.
- Keep WebM selected.
- Download.
Questions
- Are my files uploaded?
- No. The converter runs inside your browser, so your files stay on your device. You can check: open your browser’s developer tools, go to the Network tab and convert something.
- Is it free?
- Yes. Free pages show a small ad that pays for the site. Pro removes ads and lets you drop more files at once.
