About TrackMix
TrackMix is a growing set of simple, fast audio tools that run entirely in your web browser. Cut, join, convert, record and clean your audio — without installing anything, without creating an account, and without uploading your files anywhere.
Your files never leave your device
This is the part we care about most. When you open an audio file in TrackMix, it is processed locally on your own computer or phone using your browser. Your audio is never sent to a server — there is no upload, no cloud storage, and nothing for us to see. When you close the tab, it's gone.
Why we built it
Most "free" audio tools online are slow, cluttered, demand sign-ups, or quietly upload your files to their servers. We wanted the opposite: a beautiful, trustworthy place where everyday audio jobs just work — instantly, privately, and free.
How it stays free
TrackMix is supported by tasteful advertising on the tool pages (never on this page, and never intrusive pop-ups). That lets us keep every core tool free for everyone. A small optional Pro upgrade may be offered later for power users who want to remove ads and unlock larger files.
What's next
We're shipping tools one at a time. The Audio Cutter is live now — joiner, converter, recorder, normalizer and more are on the way.
