Audio Cutter
100% Free No sign-up No login No paywall
Audio Cutter trims any audio file in your browser. Upload a song, a voice note or a podcast, see its waveform drawn on screen, drag the start and end points to the part you want, and download just that part as a WAV file. Your audio is never uploaded to any server — the cutting happens locally on your device. The download is WAV (uncompressed, full quality), because browsers cannot encode true MP3 without a server; any free converter can turn it into MP3 in seconds. Perfect for ringtones, removing silence from a recording, or pulling one part out of a long file.
Click on the waveform to set the start point, drag to select a range. The shaded area is what will be kept.
How to use Audio Cutter
- Upload any audio file (MP3, WAV, OGG, M4A and more).
- The waveform appears — set the start and end times, or drag on the waveform.
- Press “Play Selection” to hear exactly what will be kept.
- Press “Cut & Download” to download the trimmed audio as WAV.
Worked example
Example: a 3-minute voice note with 20 seconds of silence at the start. Upload it, set start to 0:20 and end to the end, press Play Selection to check, then Cut & Download — you get a clean WAV with the silence gone.
Tips for better results
- Play the selection before cutting — hearing it once avoids a wrong cut.
- Leave a tiny bit of extra audio at both ends; you can always cut again.
- WAV is uncompressed, so it is bigger than MP3 but keeps full quality.
- For ringtones, cut 20–30 seconds — most phones use that length.
Frequently asked questions about Audio Cutter
Is the audio cutter free?
Yes, completely free — everything runs in your browser, no API key needed.
Is my audio uploaded anywhere?
No. Your audio never leaves your device. The waveform, preview and cut all happen locally in your browser.
What format do I get?
A WAV file (uncompressed, full quality). Browsers cannot encode true MP3 without a server, so this tool gives you WAV — any free converter can turn it into MP3 in seconds.
Which audio formats can I upload?
Any audio your browser can play: MP3, WAV, OGG, M4A and more. If the browser cannot read the file, it will say so.
Can I cut a very long file?
Yes — there is no site-imposed limit. Very long files use more memory while decoding, but cutting works the same.
Can I cut out the middle of a file?
Cut in two steps: cut from the start to the middle point, then cut the rest and keep both parts. This tool keeps one continuous selection per cut.
Why WAV and not MP3?
Browsers can decode MP3 but cannot encode it without a server. WAV keeps full quality and any free converter turns it into MP3 in seconds.
