Frequently Asked Questions

How does the MP4 to WebM converter work?

Our converter uses Remotion (remotion.dev) directly in your browser. When you upload an MP4 file, it gets processed locally on your device and converted to WebM format without ever being sent to a server.

Is there a file size limit?

Yes, currently we limit file sizes to 500MB to ensure smooth performance in the browser. For larger files, you might need to use a desktop application.

Why convert to WebM format?

WebM is an excellent format for web videos, offering good compression with high quality. It's well-supported by modern browsers and uses less bandwidth than many other formats.
