Audio Cutter — Free, No Sign-Up
Choose an audio file (MP3, WAV, OGG or M4A), then set the start and end times below.
Honest note: the trimmed clip downloads as a WAV file. MP3 export is not possible in a browser, but WAV is uncompressed full quality and plays everywhere.
How to use Audio Cutter
Choose your audio file
Click the box above or drop an MP3, WAV, OGG or M4A file onto it. The waveform appears below, with the file length and format.
Set the start and end
Type the start and end times in seconds — or drag the sliders. Press “Play selection” to hear exactly what you will keep before you cut.
Download the trimmed audio
Press “Cut Audio”. Your trimmed clip downloads as a WAV file — the part you chose, nothing else.
Example: Example: a 3-minute voice recording where the good part runs from 0:42 to 1:15 — set start 42 and end 75, and you get a clean 33-second clip.
About Audio Cutter
Cutting audio is one of the most common audio jobs: removing a long silence at the start of a voice note, keeping only the chorus of a song you recorded yourself, or trimming a podcast clip for sharing. AudioTools cuts your audio right in your browser. There is no upload, no queue and no waiting room — the file is decoded on your own device, the seconds you chose are kept, and the rest is dropped, so a cut takes seconds even on a slow connection, and your recordings stay private.
The result downloads as a WAV file, which opens in every audio app and editor. Because everything runs locally, the tool works the same on a phone, a tablet or a computer — and it is free, with no account and no sign-up. One honest limit: the exported file is WAV, not MP3, because MP3 encoding is not available in a browser. WAV is uncompressed and sounds exactly like the original.
Frequently asked questions
How do I cut an audio file online?
Choose your audio file, set the start and end times in seconds, press “Play selection” to check it, then press “Cut Audio”. The trimmed clip downloads immediately.
Which audio formats can I cut?
MP3, WAV, OGG, M4A and FLAC — any format your browser can play. The trimmed clip always downloads as a WAV file.
Is cutting audio free?
Yes. Cutting audio on AudioTools is 100% free. There is no paid plan, no length limit and no watermark.
Do my audio files get uploaded?
No. The cut happens entirely in your browser. Your files never leave your device and nothing is stored on any server.
Why does the result download as WAV?
MP3 encoding is not available in a browser, so the tool exports WAV — uncompressed, full quality, and playable everywhere. If you need MP3, convert the WAV in any audio app.
Can I cut a very long recording?
Yes. There is no fixed length limit. Very long files (an hour or more) may take a few seconds to decode on older phones, but ordinary recordings cut in seconds.
