Frequently asked questions

Why browser-based compression?

Cloud compressors upload your entire video to a remote server. This tool uses FFmpeg WebAssembly — the same engine as many desktop apps — running entirely on your device. It is slower than native software but keeps your footage private and works without an account.

Tip: For fastest results on mobile, use Smallest File or Web & Social presets and shorter clips under one minute when possible.
