Cut a part of a song or recording on a waveform, add fades and save it as MP3 or WAV.
About Audio Trimmer
This audio trimmer online works as a simple MP3 cutter for songs, voice notes and recordings. Drop an MP3, WAV, M4A or OGG file, drag the start and end handles on the waveform or type exact times, and play the selection to check it. Add a fade in or fade out for a smooth start and finish.
Save the cut as MP3 with your chosen bitrate, or as WAV for full quality. It is handy for ringtones, reels background music, podcast clips and trimming silence from recordings. Your audio is processed in your browser and never uploaded, and the tool is free with no sign-up or watermark.

- Drag the start and end handles on the waveform, or type exact times.
- Play the selection and add a fade in or out if you like.

Frequently asked questions
Is my audio uploaded anywhere?
No. The file is decoded and cut entirely inside your browser using the Web Audio API.
Can I make a ringtone?
Yes. Select 20–30 seconds, add a short fade out and export as MP3. For iPhone you will still need to convert to M4R with another app.
Why is the WAV file so large?
WAV is uncompressed 16-bit audio (about 10 MB per minute in stereo). Choose MP3 for a much smaller file.
Which bitrate should I pick?
128 kbps is fine for speech and ringtones, 192 kbps is a good default for music and 320 kbps is the highest MP3 quality.
How do I cut part of an MP3 song?
Drop the song, drag the handles on the waveform to the part you want, preview it, choose MP3 and click Export to download the cut.
How do I cut audio at an exact time?
Type the start and end times in the boxes instead of dragging. Play the selection to confirm before exporting.
