How it works
- Drop or paste one or more WebM files.
- Your browser converts them to MP4. Nothing is uploaded.
- Download the result, or a ZIP when there are several files.
Good to know: WebM is always re-encoded to H.264, so longer videos take a while. Up to 200 MB per file. Each file counts as one conversion. Not on webfrens.com.
About the formats
WebM: Open web video format, common for screen recordings and downloads.
MP4: The everyday video format that plays on phones, browsers and TVs.
Free limit
This counts as one conversion. You get 5 every 30 minutes for free. Each file counts as one, so a batch of three files uses three.
Questions and answers
How do I convert WebM to MP4?
Drop your WebM files on this page, or choose them, then press Convert. Your browser does the work and you download the MP4 file, or a ZIP when there are several.
Will I lose quality?
Barely. WebM is re-encoded to H.264 at good quality, which takes a while because your own device does the work.
Can I convert several files at once?
Yes. Several files download together as a ZIP. Each file counts as one conversion, so three files use three of your free conversions.
Why does it take a while?
Your own device converts the video, with no server, and the converter is about 30 MB to download the first time. Phones are slower than computers, so short clips work best.
