What audio formats can I trim?
Our audio cutter supports MP3, WAV, OGG, FLAC, and M4A files. The trimmed output is exported as high-quality WAV for maximum fidelity.
Can I preview before cutting?

Can I add fade effects?
Yes. Enable fade-in and fade-out from the controls panel. This creates smooth volume transitions at the start and end of your trimmed clip — great for ringtones and samples.
Is there a maximum file size?
There's no hard limit — it depends on your device's available memory. Most users can trim files up to several hundred MB without issues on modern devices.
Can I make ringtones with this tool?
Absolutely. Upload your song, select the 20–40 second section you want as a ringtone, add a fade-out, and download. The WAV output can be converted to your phone's preferred format.
Does it work on mobile?
Yes. The audio cutter works in any modern mobile browser (Chrome, Safari, Firefox). The waveform editor is touch-friendly, so you can pinch to zoom and drag to select on your phone or tablet.
Are my files uploaded to a server?
No. All cutting happens locally in your browser through the Web Audio API. Your audio never leaves your device, nothing is stored on our servers, and no account is required.
How precise is the cut?
Cuts are sample-accurate. Internally we use the raw AudioBuffer, so you can trim to the exact millisecond. Zoom in on the waveform for frame-perfect start and end points.
Can I use this as an iPhone ringtone maker?
Yes. iPhone ringtones must be under 40 seconds. Trim your selection to 20-40 seconds, add a fade-out, and download the WAV. Convert to .m4r in any free converter and import into Finder or iTunes.
How is this different from Audacity?
Audacity is a powerful desktop app but requires installation, has a steep learning curve, and uses an outdated interface. RemoveVocals Audio Cutter runs in any browser with a clean visual waveform editor — ideal for quick single trims and ringtones without installing anything.
Is there a watermark?
No. There are no watermarks, no limits on file length, and no daily quota. Use it as much as you want.
