Audio Cutter

How to cut audio online — 3 steps

What is an online audio cutter?

An online audio cutter is a browser tool that cuts a section out of an audio file without installing anything. You choose the start and end of the part you want — a chorus, a quote for a video, a ringtone-length clip — preview it, and export just that span.

RapKit's audio cutter runs entirely on your device: files never reach a server, and cutting copies the original audio data inside your selection instead of re-compressing it, so the export sounds exactly like the source. Because trimming is just precise cutting, the same page works as an audio trimmer for shortening long recordings.

Cut every audio format — MP3, WAV, M4A, FLAC, OGG and more

Import MP3, WAV, M4A/AAC, FLAC or OGG; export MP3, WAV, M4A, M4R (iPhone ringtone), OGG or FLAC. Cutting one format every day? Each has a dedicated cutter built on the same engine: the MP3 Cutter, WAV Cutter, M4A Cutter.

Cut songs for videos, posts and ringtones

The everyday jobs are all two minutes each: shave a long intro off a song so a video starts on the good part, crop a track to a 15-second loop for a post, isolate the verse you actually want to rehearse, or pre-cut the chorus before handing it to a ringtone. The waveform makes the work visual — drag the handles until the shaded span covers exactly the part you keep, and nothing outside it survives the export.

Preview runs on the selection before you commit, so the ear signs off on the cut — start a little early, end a little late, tighten, listen again. Two minutes of nudging beats exporting three times.

Cut without losing quality

The question every cutter has to answer: does the cut hurt? Here the answer is no — trimming copies the original audio data inside your selection without re-compressing it, so the exported span sounds identical to the source. Pair that with lossless exports (WAV and FLAC stay on the format list) and the cutter fits at the front of a quality-sensitive chain: cut losslessly first, then let downstream tools work on exactly the audio you chose.

Long files, phones and limits — stated plainly

Honest numbers: browser processing comfortably handles up to about 60 minutes of audio on a desktop and around 15 minutes on a phone, which covers albums, DJ sets and long podcasts. Bigger files are not a refusal — signing in moves them to cloud processing. And the privacy rule stays the same everywhere: cutting happens locally, and files only reach a server if you explicitly save a result to your library while signed in.

The audio cutter inside a bigger workflow

Cutting is usually step one, and the neighbours take over from there. Hand the chorus to the Ringtone Maker for an M4R. Give the extracted interview a soft landing with the audio fader. Feed a cleaned-up stem onward to the vocal remover or the MIDI converter. Because every tool on this site passes files in the same browser under the same nothing-uploaded rule, a chain that used to mean three apps and two uploads now means one tab and zero.

The handoff matters less than the start, though: whatever the chain, it begins with a clean cut. Cutting precisely once — instead of trimming repeatedly across tools — keeps the audio one generation old no matter how long the pipeline grows.

Common cutting questions, answered honestly

Three questions come up weekly. "Will the ends click?" — not here: spans are cut on the format's own boundaries, and a fader pass removes any last harshness. "Can I cut a two-hour recording?" — on a desktop, yes, up to roughly an hour comfortably in the browser, longer with a free account's cloud processing. "Does cutting an MP3 ruin it?" — the MP3 page re-encodes the selection at a high bitrate to stay frame-accurate; the difference is inaudible in real listening. If a question is not answered here, the FAQ above carries the rest.
