Trim MP3s online, free
Intros that drag, outros that ramble, one perfect verse buried in a long recording — trimming MP3s is the most common audio job on the internet, and it shouldn't require installing Audacity. This cutter shows your track as a draggable waveform: select the part to keep (or the part to cut out), preview it, add fades so edits don't click, and export MP3, WAV, or FLAC. Everything decodes and renders locally — your audio never touches a server.
How to trim an MP3
- 1Drop your MP3 on the trimmer above. The waveform renders in seconds.
- 2Drag the waveform to select — or type exact seconds. Hit Preview to hear the cut before committing.
- 3Cut and download. Add fades for smooth edges, pick MP3/WAV/FLAC, and save.
Clean cuts every time
Fade everything
Even a 0.3s fade erases the click that betrays an edit. Use 1–2s fades for music, 0.2–0.5s for speech.
Cut the middle out
Removing an umm-filled middle? Switch to CUT PART OUT mode — both halves join seamlessly.
Watch the volume
Boosting past 100% can clip and distort. If the tool warns about clipping, back the volume down a touch.
Frequently asked questions
How do I trim an MP3 online free?
Drop it on the trimmer above, drag the waveform to select, preview, and download. No accounts, no uploads, no watermarks.
Will trimming reduce audio quality?
Barely — the selected audio is re-encoded once at your chosen bitrate (192 kbps default). For zero-loss cuts, export WAV or FLAC.
Can I remove a section from the middle?
Yes — switch to CUT PART OUT mode, select the unwanted middle, and both sides join into one file.
What formats can I export?
MP3 (universal), WAV (lossless), or FLAC (lossless, smaller). Bitrate is adjustable for MP3 from 96 to 320 kbps.
Are my audio files uploaded?
No. Decoding, cutting, and encoding all run 100% in your browser.
