WAV Cutter

How to cut a WAV online — 3 steps

What is an online WAV cutter?

An online WAV cutter cuts a section out of a WAV file without installing anything. Choose the start and end of the part you want — a chorus, a quote for a video, a clean intro — preview it, and export just that span.

RapKit's cutter runs entirely on your device: files never reach a server, and cutting a WAV is lossless — the selected samples are copied as-is into a fresh WAV, so the export sounds exactly like the source. It's the same engine behind our Audio Cutter, pre-tuned for the WAV workflow.

WAV cutter or WAV trimmer — it's the same tool

People search for a WAV trimmer when they want to shorten a long recording, and this cutter when they want a specific part out of a session — it's the same drag-and-export job either way. Trim an interview down to the quote, shorten a live take, or cut the intro off your AI Song Generator export before you post it.

Lossless by default — and smaller exports one click away

WAV stores uncompressed samples — about 10 MB per minute — which is why it's the format producers and podcasters master in. Cutting a WAV here copies those samples as-is: the export is identical to the source, sample for sample.

Need it smaller? Pick MP3 or M4A from the format dropdown and the same cut compresses down for sharing — or hand it to the Audio Compressor for bitrate control, or the Audio Converter for any other format.

Why WAV cutting stays lossless here

WAV is the format where losslessness is the whole point, and the cutter respects that: the selected samples are copied as-is into a fresh WAV, untouched by any encoder. What you marked is what you get — sample for sample. That makes this the right tool for archival snippets, sample packs, and any moment where "the file changed" is unacceptable. If a smaller file is what you actually need, the format dropdown exports the same span as MP3 or M4A in one click.

Cutting long WAV recordings — desktop and phone limits

WAV files are heavy — roughly 10 MB per minute — so the limits are worth knowing before you load a two-hour session: a desktop browser comfortably cuts up to about 60 minutes of WAV, a phone around 15. Longer files are not a dead end: signing in moves the job to cloud processing. And because everything is uncompressed PCM, the waveform you see is the audio itself — zoom in far enough and individual transients are right there to cut between.

What a cut WAV is good for

A lossless span is a working part, not a finished copy: producers chop it into sample packs; editors drop it onto timelines where repeated re-encoding would pile up damage; archivists cut highlights out of long recordings without touching the master; and a fader pass afterwards turns any span into a clean loop or a polished ending. Cut first, keep it lossless, and every later step starts from exactly the audio you chose.

The WAV cutter inside a bigger workflow

A lossless span invites a lossless journey. Cut the take, soften its edges with the audio fader, convert a copy with the audio converter when a smaller file is needed, and the master span never degrades — because the cutter's output is the same uncompressed audio it read. Studios think in these chains: record, cut, edit, archive, with the WAV sitting untouched at the centre. This page is the cut step, done locally, at no cost.

Common WAV cutting questions

"Why is my cut as heavy as the original?" — because it is lossless: ten megabytes a minute is the format, not a bug, and the dropdown exports MP3 or M4A when size matters. "Can I cut on a phone?" — yes, about fifteen minutes of WAV; desktops take an hour. "Does the cut re-encode anything?" — no: selected samples are copied as-is into the new file. If it is not answered here, the FAQ above has the longer version.

Privacy and quota — the operational bits

The mechanics stay boring on purpose: cutting runs locally, the WAV only reaches a server if you sign in and deliberately save the span to your library, and guests get three exports a day against ten for free accounts. No watermark on the lossless output, no trial countdown, no email tollbooth — the WAV cutter treats a studio-grade operation like the everyday task it has become.
