A compact audio editor for quick jobs: cut sections out, apply fade in and fade out, boost or lower volume, speed tracks up or down, and reverse playback. Every edit is applied on your device when you export — the original file always stays untouched on your disk.

How to use the MP3 Editor

  1. Open your file

    Drop an MP3, WAV, M4A or other audio file onto the editor. It decodes instantly on your device.

  2. Edit

    Select a range to keep or delete, then open Adjust to add fades, change volume, alter speed from 0.5× to 2×, or reverse the track.

  3. Export the result

    Save your edit as MP3 at up to 320 kbps, or as lossless WAV. Edits are rendered offline in your browser before download.

Frequently asked questions

What can this MP3 editor do?

It covers the most common quick edits: trimming and cutting, fade in and out, volume adjustment, speed change from 0.5× to 2×, and reversal. For multi-track recording or heavy production, a DAW like Audacity is still the better tool — this one is for fast, private, in-browser edits.

Are my edits destructive?

No. Your original file stays exactly as it is on disk. All edits are held as settings in the editor and only rendered into a new file when you export.

How does speed change affect pitch?

Speed and pitch move together, like a record played faster or slower: at 2× the audio plays about an octave higher, at 0.5× about an octave lower. Use small steps for subtle changes. If you need the tempo changed while keeping the original pitch, export first and run the file through a dedicated time-stretch tool.

Can I undo a change?

Yes. Press Ctrl+Z (Cmd+Z on Mac) to step back through your recent edits, or click Reset to reload the original file state.

Is it safe for confidential recordings?

Yes. Audio is decoded and rendered locally with the Web Audio API — it is never transmitted over the network, which makes it suitable for interviews and other confidential material.
