Who runs ClipDen

ClipDen is designed, written and maintained by an independent developer who prefers small, focused tools over bloated apps. Speed, a clean interface and careful handling of your data come first.

Why we built it

Small media jobs like saving the audio of a lecture recording or trimming a screen capture usually mean installing a heavy video editor or uploading large files to a remote converter. ClipDen runs FFmpeg compiled to WebAssembly inside the browser, so even large files are processed on your own machine without waiting for an upload.
