How to trim audio online

- Drag the start and end handles to mark your region; exact times and selection length are shown below the waveform.
- Choose Keep selection or Remove selection, and add fade in / fade out if you want smooth edges.
- Press Preview selection to check the cut, then download it as WAV or 320 kbps MP3.
This audio trimmer and MP3 cutter is built around a visual waveform, so you cut by sight and sound rather than typing timestamps: spikes show where the drop hits, silence shows where the take ends. The Remove mode is the underrated half — it deletes the selected region and stitches the remainder together with a tiny crossfade, perfect for cutting a cough out of a podcast or an ad out of a recording. Everything runs locally in your browser; files are never uploaded.
Typical jobs: ringtones from a chorus, intro clips for streams, tight voice-over takes, sample chopping and shortening voice memos. To glue several clips together afterwards, hand the pieces to the Audio Joiner.
FAQ
How do I cut a section out of an MP3?
Drop the MP3 on the page, drag the two handles on the waveform around the part you want, and choose Keep selection to save just that part — or Remove selection to delete it and keep everything else. Then press Cut now and download the result.
Is trimming lossless?
The file is decoded to raw audio, cut at the sample level, and exported. Choose WAV and there is no further quality loss after decoding; choose MP3 and the clip is re-encoded at 320 kbps, which is a small but technically lossy step. For ringtones and clips either is fine.
Can I add a fade in or fade out to the clip?
Yes — separate fade-in and fade-out sliders apply smooth linear fades of up to 3 seconds to the result, so a clip cut from the middle of a song does not start or stop abruptly.
Is this MP3 cutter free, and are my files uploaded?
Free, unlimited, no signup and no watermark. The waveform, the cutting and the export all happen inside your browser — your audio is never sent to a server.
