About ClipForge
ClipForge is a free, privacy-first media studio that runs entirely in your web browser. There are no uploads, no watermarks, and no accounts. Every tool — screen recording, trimming, compression, format conversion, GIF creation, audio extraction and vocal removal — processes your files on your own device using WebAssembly, the Screen Capture API and the Web Audio API.
Why we built it
The web is full of “free” media tools that upload your private files to a server, stamp a watermark on the result, or lock features behind a paywall. We think basic media utilities should be fast, private and free. Because ClipForge never sends your files anywhere, it's genuinely private by design — and it costs almost nothing to run, so it can stay free.
How it works
The heavy lifting is done by ffmpeg.wasm (FFmpeg compiled to WebAssembly) for video and audio processing, the browser's native MediaRecorder and Screen Capture API for recording, and the Web Audio API (with optional in-browser AI via onnxruntime-web) for vocal separation. Tool pages run in a cross-origin-isolated context so processing can use multiple threads for speed, with a single-thread fallback that works everywhere.
