How to Cut and Trim Audio

1 Upload the 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 Audio file.

Audio Cutter FAQ

Does the format limit where I can cut?
+
It does. this format is read and written by the same streaming pipeline as everything else we support. That is precisely what decides whether a cut can be placed arbitrarily or has to land on a structural boundary.
Yes — the codec is detected from the stream, so a mislabelled extension does not derail the job. It explains most of the "the cut is a fraction of a second off" surprises.
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.
Concretely, the cut is stream-copied where the codec allows it and sample-exact where the source is lossless, so you get the cheapest correct path for the file you actually uploaded. You set the start and end points on the waveform or the timeline and keep what is between them.
Yes. The set queues in parallel with identical settings, which is how you process an album or a podcast back catalogue without repeating yourself.
Yes — ID3, Vorbis comments and MP4 atoms are carried across along with embedded artwork, so processed files still sort correctly in a music library.
Yes: free accounts process audio up to 15 MB per file whichever codec you brought; ffmpeg handles the decode and encode. In practice that limit only bites on uncompressed WAV; a compressed file of the same length is nowhere near it.
It depends on the source. Lossless input (WAV, FLAC, AIFF) is edited sample-exactly and loses nothing. Lossy input has already discarded detail once, so where the job can be done by copying the encoded stream rather than re-encoding it, that is the path taken.
WORD.to is built around the editable end of a document's life — the DOCX that is still being written, still being styled and still being argued over, before anyone flattens it for sending. Office files are containers full of other people's media — images, embedded audio, fonts — so the work people need on them is usually the work they would need on those contents anyway. Audio Cutter shares the upload, the caps and the account with the conversions for that reason.
The converter on this site takes documents out to PDF for sending, to images for embedding and to plain text for anything that has to read them programmatically, and back the other way. Doing that afterwards keeps the editable original around, which is the part you cannot get back once it has been flattened.
The engines are shared — the same document toolchain, the same workers, the same limits. What a Word site adds is a view on what survives leaving the Office format and what does not, which is the question every one of these jobs actually turns on. It also starts from one fact about the format this site is named after: the document is a zip of XML, so text edits are cheap and the weight is almost always the embedded images.
No account, and nothing is kept: uploads are deleted from the workers shortly after the job finishes, nothing is read and nothing is indexed. Free accounts exist for history and batch size, not for access.
