How to cut an MP3

  1. 01

    Open your MP3 in the browser

    The file is read locally with the Web Audio API and never uploaded.

  2. 02

    Mark the cut points on the waveform

    Every cut point can be dragged and re-adjusted until it is exactly where you want it.

  3. 03

    Export the result

    Cut one section, or cut several at once - every clip is exported together in a single pass.

Cut MP3 online, free, no install

An MP3 cutter online should not ask you to install a full editor first. Nothing is installed here: the cutter loads with the page, reads your file locally and returns the result as a download. No account, no upload queue, no file-size ceiling.

Remove a section from the middle of an MP3

This is the job a trimmer cannot do and a splitter does not offer directly: mark two cut points around an ad read, a cough, a wrong take or a stretch of silence and export everything on either side. Cutting the middle out of a file is what people actually mean when they search for an MP3 cutter.

Cut MP3 vs trim MP3 vs split MP3

Cut MP3: remove a section, keep the rest. Trim MP3: keep one section, discard the rest. Split MP3: turn one file into many tracks. The three searches look alike and the three jobs do not, so each has its own page here - and all three share one engine.

Cut MP3 without re-encoding

MP3 and AAC are cut on frame boundaries, WAV by byte range and M4A on sample boundaries, so the audio stream is copied rather than re-encoded. There is no generation loss. Free exports keep the original format; Pro can re-encode to MP3, AAC or Opus if you want a smaller file.

Supported formats

MP3 / AAC
Cut on frame boundaries - no re-encode
WAV
Cut by byte range - no re-encode
M4A / M4B
Cut on sample boundaries - no re-encode
FLAC / OGG
Decoded first; roughly 2 hours max in a browser tab

Questions

Is this MP3 cutter free?
Yes. Cutting, unlimited clips and unlimited exports in the original format are free - no account, no watermark, no ads. Pro is a one-time $19.90 purchase that adds batch ZIP export, CUE / chapters export and re-encoding to MP3, AAC or Opus.
Can I cut out the middle of an MP3?
Yes. Place two cut points around the passage you want gone and export the parts on either side as separate clips.
Does cutting an MP3 re-encode it?
No. MP3 is cut on frame boundaries, so the frames are copied unchanged and the original bitrate and tags are kept.
Can I cut several sections at once?
Yes. Add as many cut points as you need - every clip is exported together in one pass.
Is there a file size limit?
No fixed limit for MP3, WAV, M4A and AAC, because nothing is decoded as a whole. FLAC and OGG are decoded first and cap out at roughly two hours inside a browser tab.
Can I cut an MP3 on my phone?
Yes, it runs in any modern mobile browser. For precise cut points on a long file, a larger screen is easier.
