Trim, convert, and record video in your browser.
Most "free online video" sites make you upload the whole clip to their servers, wait in a queue, then hand back a watermarked download — after your footage has sat on hardware you do not control. CipherForces runs the work on your own machine: FFmpeg compiled to WebAssembly handles trimming, muting, compression, frame extraction, and format conversion, while screen and webcam capture use the browser's built-in recording APIs. Nothing is uploaded, there is no queue, and there is no watermark. That matters most for the video people actually edit at home — screen recordings of private accounts, family clips, unreleased work, and anything you would not post publicly.

The screen recorder and webcam recorder use the browser's own capture APIs — no extension, no desktop app, no account.
The same FFmpeg the pros use
FFmpeg-WASM does the heavy lifting, so a trim or format change is the real thing, not a lossy re-wrap — it just runs in your tab instead of a data center.
People ask these things.
Can I trim or compress a video without uploading it?
Yes. Every video tool here loads your file into the browser and processes it with FFmpeg-WASM on your own machine. Open the Network tab while you work — you will not see an upload.
Why is the first video operation slow to start?
The FFmpeg engine (about 25 MB) downloads once on first use, then is cached. After that, operations start immediately. Screen and webcam recording do not need it at all.
