FAQ
Why does the first conversion take longer?
Your browser downloads a small WebAssembly video engine the first time you use any video tool. It's cached afterward, so later conversions start instantly.
Is there a file size limit?
Only what your device's memory allows — there's no artificial server-side limit since nothing is uploaded.
Need to change the format instead?
Use MOV to MP4 to convert format without necessarily reducing size.
