How to Cut and Trim MP3

1 Upload the MP3 audio files you want to cut.
2 Drag the start and end handles on the waveform or the timeline, or type exact timecodes if you already know them.
3 Preview the selection and run the cut — the part you keep is copied through untouched wherever the format allows it.
4 Download the trimmed MP3 file.

MP3 Cutter FAQ

How precisely can I place the start and end points?
+
You can type exact timecodes rather than only dragging, and the preview scrubs to the position as you move it. How exact the result can be depends on the format: some allow a cut anywhere, others snap to the nearest frame or keyframe.
Yes — cut the piece before it and the piece after it, then merge the two results. That is deliberately two steps because it keeps both halves on the fast, lossless path instead of forcing a full re-encode.
Not if the format allows a stream copy — the data you keep is bit-identical to the source and the job finishes in about the time the upload took. Only a frame-exact cut on a format that cannot do it cheaply needs a re-encode.
Concretely, the cut is made on frame boundaries and the surviving frames are copied through without re-encoding, so the audio you keep is bit-identical to the original — no second generation, and the job finishes in about the time it takes to upload. You set the start and end points on the waveform or the timeline and keep what is between them.
Yes. Upload the set and they process in parallel with the same settings, which is the practical way to handle a podcast series or an album rather than repeating the job by hand.
No. MP3 Cutter is free without an account and adds no audio watermark or spoken tag to the output. Your upload is deleted from the workers shortly after the job completes.
MP3, AAC, M4A, OGG, Opus and WMA are the lossy codecs handled directly, and lossless sources (WAV, FLAC, AIFF) can go in the same batch. The codec is probed from the stream, so an incorrectly named file still works.
A lossy file has already discarded detail once, and re-encoding discards more — that is generation loss and it does not undo. Wherever the job can be completed by copying the encoded stream rather than re-encoding it, that is what happens, and the audio comes back bit-identical.
JPEG.to is built around the format that carries nearly every photograph in existence — thirty years old, opened by literally everything, and still the right default for a photographic image. The jobs people bring here are the ones a photograph collects over its life — too big to email, wrong dimensions for a form, wrong way up out of a phone. MP3 Cutter runs on the same upload and the same account as the conversions because that is where those jobs land.
The converter on this site moves images to and from JPEG, PNG, WebP and HEIC, which is where the trade between file size and one more generation of loss gets settled. Deciding the format last rather than first is the whole point: every extra save of a photographic image is another generation, and the fewer of them you spend, the more of the picture survives.
Yes — the same libraries, the same workers, the same caps. The difference is which advice is on the page, and here that advice is built on one property of the format the site is named after: the .jpeg and .jpg extensions are the same bitstream, so nothing here behaves differently from a .jpg — only the filename changes.
Nothing is kept and no account is needed. Uploads are removed from the workers shortly after the job finishes; nothing is looked at, listed or indexed. An account buys history and larger batches, not access.
