Which video format should I use if I'm not sure what's expected?

MP4 is the safest default -- it has the widest compatibility across devices and platforms of any common video format.

Why does converting take a while for a large file?

Converting between formats generally re-encodes the entire video, not just relabels the file, so larger files or longer videos take noticeably longer to process.

What is this tool?

Converts a video between MP4, web-optimized MP4 (fast-start for HTML5), WebM, and MOV. Prefer “MP4 for web” for sites; use WebM only when you specifically need a .webm file. Runs entirely in your browser -- the video never leaves your device.

How to use it

Upload your video, choose the format you want to convert it to, and download the converted file once processing finishes.

For websites and embeds, choose “MP4 for web” (fast-start). WebM works in modern browsers but is slower to encode in-browser; use a short clip if it feels stuck.
