FAQ
How do I convert AVI to MP4?
Drop the AVI file on this page and select Convert. The MP4 downloads when it is ready.
Are my files uploaded?
Files are processed in your browser with a local copy of FFmpeg. They are not uploaded to Super Media.
Is there a size limit?
Files up to 250 MB. Longer or high-resolution videos take longer because your own device does the work.
