Free Online Audio Cutter
Free Online Audio Cutter is free to use on ALSBKIN. If it is useful to you, you can also visit the ALSBKIN YouTube channel and subscribe to support the independent music and tools project.
SUBSCRIBE TO MY YOUTUBE CHANNELCut MP3, WAV and supported audio files online for free. Select the exact section you want, preview it, add optional fades and export the result directly from your browser.
AUDIO TOOLSHow it works
1. Select your audio file.
2. Drag the blue selection handles or enter START/END times manually.
3. Preview the selection.
4. Optionally enable Fade In/Fade Out.
5. Choose WAV or MP3 and export for free.
Note: supported input formats depend on your browser and device. WAV export is generated natively. MP3 export is encoded locally in your browser using lame.js.
Free MP3 and Audio Cutter in Your Browser
Use this free online audio cutter to trim MP3, WAV and other browser-supported audio files with precise start and end points. Zoom the waveform up to 8×, preview your selection, add optional fade in or fade out, and export the result as WAV or MP3.
Your audio is processed locally in the browser, so the file stays on your device instead of being uploaded for processing. Need to trim a video instead? Try the Free Online Video Cutter, or browse all ALSBKIN Free Online Tools.
Audio trimming without a full editor
Trim supported audio files, preview the selected range, refine cut points on the waveform and export the result from the browser. This is useful for removing silence, isolating a section, preparing a short preview or making a clip before further editing.
When this tool is useful
Use the cutter to isolate a chorus, remove silence, prepare a short preview, create a ringtone-length excerpt or trim a recording before another editing step. Always listen around the cut points before exporting, because a technically correct cut can still sound abrupt if it lands inside a word, note or reverb tail.
Practical limits and quality checks
For spoken audio, cut during natural pauses where possible. For music, zoom in around transients or bar boundaries and leave enough tail for reverberation. If the source is already heavily compressed, exporting repeatedly through lossy formats can reduce quality; keep a lossless master when quality matters.
Privacy and responsible use
The selected audio is handled in your browser for trimming. Before cutting an interview, song or voice memo, make sure you are authorised to use the recording and keep the untouched source until you have checked the exported start and end points.
Frequently asked questions
Can browser audio processing change sound quality?
Cutting itself changes duration rather than tone, but an export can require re-encoding. Choose WAV when you need a lossless editing copy; use a compressed format when file size matters more than preserving an intermediate master.
Why can results differ between browsers or devices?
Precise cut points can vary slightly with codec frame boundaries and browser decoding. Zoom or preview around the intended edit, and use a modern desktop browser for long or high-bitrate files that demand more memory.
