Frequently Asked Questions
Is my audio file uploaded anywhere?
No. Every edit — cuts, effects, history — happens locally in your browser using the Web Audio API. Your file never leaves your device.
What's the difference between MP3 Editor and MP3 Cutter?
MP3 Cutter is a simpler cut-and-trim-only tool. MP3 Editor adds multi-region marking, Reverse, and a full effects suite (echo, reverb, EQ, normalize) with a named, jumpable history.
Can I undo a mistake?
Yes — every action is recorded in the history panel, so you can jump back to any earlier point, not just undo one step at a time.
Which audio formats are supported?
You can open MP3, WAV, M4A, FLAC, OGG and most other common audio formats, and export as MP3 or WAV.
Is there a cost to use any of the effects?
No. Every effect and export option is completely free, with no premium tier or watermark.
