How to cut an audio file
- Drop your audio file into the box. MP3, WAV, M4A, AAC, FLAC and OGG work, and so do videos — the sound is used.
- Drag the handles on the waveform to the start and end of the part you want. Click the waveform to jump there, or type exact times.
- Use ▶ Play selection to listen, add a fade in or out if you like, and choose the format.
- Click ✂ Cut audio and download the file.
Which format should I save?
- MP3 — plays everywhere; 192 kbps is great for music, 128 kbps for speech.
- WAV — lossless, for further editing in a DAW or for archiving.
- M4A (AAC) — smaller than MP3 at the same quality; ideal for Apple devices.
- M4R — an iPhone ringtone (see the Ringtone Maker).
Why add a fade?
A hard cut in the middle of music clicks or sounds abrupt. A short fade-out of 1–2 seconds makes the end feel natural, and a fade-in softens a start in the middle of a song. For speech, a 0.5 s fade is usually enough.
Ideas
- Cut the intro and outro off a podcast or voice memo.
- Make a 30-second clip of a song for a video or a presentation.
- Keep just one answer from a recorded interview.
Need the sound from a video first? Use MP4 to MP3. Converting whole files instead? WAV to MP3 and M4A to MP3.

Frequently asked questions
Which audio formats can I cut?
MP3, WAV, M4A, AAC, FLAC, OGG and Opus, plus the sound of MP4, MOV and WebM videos.
Can I cut audio without losing quality?
Save as WAV for a lossless result. MP3 and M4A are re-encoded; at 192 kbps or more the difference is not audible.
Can I add a fade in or fade out?
Yes. Choose a fade of 0.5 to 3 seconds for the start and the end.
Is there a length limit?
No fixed limit; very long files only depend on your device’s memory.
Is my audio uploaded?
No. Everything happens in your browser.
