Common questions
How much smaller will it get?
It depends on the video, but 50 to 90 percent smaller is common. Lowering the width saves the most; the Small quality setting saves more but looks softer.
Will it look worse?
Compressing always trades some detail for size. High keeps most detail, Medium suits phones, Small is for when the size limit matters more than looks.
What size does WhatsApp or email allow?
WhatsApp allows about 2 GB for documents but compresses video itself, and many email services stop at 20 to 25 MB. Compress, then check the size shown after.
Is my video uploaded anywhere?
No. The conversion happens inside your browser tab, so your video never leaves your device. We cannot see it or keep a copy.
Why was the first conversion slow to start?
The first time you convert audio or video, your browser downloads the conversion engine (ffmpeg, about 30 MB) from a public CDN. After that it is cached, so the next ones start straight away. Your files are not part of that download.
How big a file can I convert?
Everything runs in your browser's memory, so the limit is your device. We suggest about 500 MB on a computer and 100 MB on a phone. Beyond that, the tab may slow down or run out of memory. A computer is much faster than a phone.
