About FFmix
FFmix is a local-first FFmpeg GUI for macOS that shows the exact command before it runs — drop in video, audio or images, pick a task or describe it in a sentence, confirm, and everything processes on your Mac. Files never leave the device.
FFmix is, in one line, a Local-first FFmpeg GUI for Mac. It turns the power of the command-line tool ffmpeg into a native Mac app that anyone can use — without sending your files anywhere.
What FFmix is
Every job — compress, convert, extract, GIF, subtitles — runs locally through the bundled, open-source ffmpeg engine. There is no upload step, and it works offline.
Expand “Advanced” on any task to read the exact ffmpeg command before it runs. You can copy it, edit it, or switch to manual mode. Nothing is hidden behind the buttons.
Describe a job in a sentence and FFmix lays out an editable, step-by-step plan. It never executes until you review and confirm — and only the sentence you type is ever sent for parsing, never a file.
What FFmix is not
- Not an online converter. Your media is never uploaded to a server. Processing happens on your own Mac.
- Not a game. “FFmix” is a macOS media tool for video, audio and images — unrelated to similarly named mobile games or music-mix sites.
- Not a black box. FFmix doesn’t hide ffmpeg from you; it shows the exact command it runs and lets you edit it.
- Not a subscription wall. Every local task — compress, convert, extract, GIF, trim — is unlimited on the free version. Pro is optional.
