How It Works

Edit Audio in
Your Browser

1. Drop your file. Load any audio file. The waveform renders instantly so you can see exactly what you're working with.

2. Select & edit. Click and drag on the waveform to select a region. Hit Keep Selection to discard everything outside it, or Remove Selection to cut that section out. The waveform updates immediately.

3. Keep editing. Make as many edits as you need. Use Undo and Redo to step through your edit history at any point.

4. Finalise & Download. When you're happy with the result, hit Finalise to get your 192kbps MP3.

Undo / Redo
Every edit is saved to a history stack. Step back through your changes with Undo and forward again with Redo — up to 10 steps.
Live Waveform
The waveform updates after every edit so you always see exactly what your audio looks like before you download anything.
Play Selection
Before committing an edit, play back just the selected region to confirm it's exactly right.
Completely Private
All processing runs in your browser using FFmpeg.wasm. Your audio never leaves your device at any point during editing.
