100% Private, your clips never leave your browser. Everything is joined and encoded locally on your device using WebAssembly. Nothing is uploaded to our servers.
Each clip is scaled to a common canvas (the first clip's size, or a size you choose) and re‑encoded so they join cleanly, then FFmpeg stitches them together with your chosen transition. Your music track is looped or trimmed to fit and automatically ducked, meaning it lowers whenever there's talking.
Because it all runs on your own device, longer montages with many clips take time and memory, just bear that in mind.
