Why does compressing video take long?

FAQ

Is it safe?

Yes, everything happens locally in your browser using FFmpeg WebAssembly. Your video is not uploaded to a server.

Why does loading take so long?

The first time, the FFmpeg files (~30MB) are loaded. This one-off download is needed to process videos in your browser. After that it is faster.

Which format do I get back?

The compressed video is downloaded as MP4, which is supported almost everywhere.

What does CRF mean?

CRF (Constant Rate Factor) sets the quality. The lower the number, the better the quality but also the larger the file. CRF 20 = high quality, CRF 28 = good balance, CRF 35 = smallest file.
