Cutting a long video into Stories-sized pieces is a small job that the usual tools make heavy. You upload the file somewhere, wait for a server to process it, and trust whoever runs that server with your footage. For a thirty second task, that is a lot of friction.
Cutstory does the whole thing in the browser. A WebAssembly build of ffmpeg runs on the visitor device, so the file is never uploaded and nothing is stored on a server. The engine is 31 MB, so it loads only when the first video is picked and the page itself opens instantly. There is no account, no install, and no backend to run, which is also why the tool is free.
It is the fastest thing we have built, and the easiest to check: open it, cut a video, and see for yourself whether it works.
The Shift:
- From: uploading a video to somebody else’s server and waiting for it to come back
- To: cutting it on your own device in seconds, with the file never leaving the phone
