Need to shorten a long video? Drop it here, set the start and end times using the visual timeline, preview your selection, and download the shortened clip. All processing happens locally in your browser — your video is never uploaded.
No data transfer — all data stays on your device!
Shorten Videos Privately
WebConverter shortens videos using FFmpeg WebAssembly running in your browser. Your video files stay on your device the entire time — nothing is uploaded to any server. The trimming uses stream copy for maximum speed and zero quality loss.
Features
Near-Zero CO₂
Server-based converters upload your file, process it remotely, and send it back — consuming network and data-centre energy on every request. WebConverter runs entirely on your device, so the only energy used is your local CPU. No data transfer, no server electricity.
Install for Offline Use
WebConverter works offline as a Progressive Web App. Click "Add to Home Screen" on mobile or the install button in your browser's address bar. Once installed, you can convert files without any internet connection.
