Frequently Asked Questions
Q. Which video formats are supported?
Input supports MP4, AVI, MOV, WebM, MKV, FLV, WMV, M4V, 3GP and more. Output formats available are MP4, WebM, AVI, MOV, and MKV.
Q. Are files uploaded to a server?
No. All conversion happens entirely in your browser. Files are never sent to any external server.
Q. Why does the first conversion take longer?
On first use, the FFmpeg engine (~30 MB) is downloaded once. After that it is cached and runs much faster.

There is no hard limit, but files over 200 MB will take longer. We recommend staying under 500 MB for the best experience.
