FFmpeg WebCLI brings the full power of FFmpeg to your browser. Edit, transcode, and process video locally with zero cloud dependency.
Start Editing FreeEvery online video editor forces you to upload your footage to their servers. You lose privacy, wait for processing, and depend on their uptime. Desktop apps are clunky. The middle ground doesn't exist.

Write command-line filters in a modern UI. Get the power of FFmpeg with the ease of a graphical editor.
Download once, edit forever. Your browser has everything. No internet needed after the initial install.
100% compatible with FFmpeg filters and codecs. Use the same commands you know from the CLI.
Everything stays on your machine. No telemetry. No file sharing. You own your work completely.
See your edits instantly. Adjust filters on the fly with a modern preview system.
Process multiple files at once. Automate repetitive tasks with command templates.
