The Online MP3 Cutter provides visual audio trimming with millisecond accuracy. Decode audio into a 32-bit floating-point PCM waveform directly in your browser with zero lag and instant export.
How to Use
Drop any MP3, WAV, AAC, or M4A file to decode its 32-bit visual waveform in RAM.
Drag the start and end markers to isolate your segment down to the exact millisecond, and toggle fade-in/fade-out.
Download your trimmed audio clip as a high-bitrate 320 kbps MP3 or lossless WAV file.
Ringtone Clip Ready
320 kbps High-Res MP3
Load your MP3 or audio file into the cutter, zoom in on the visual waveform, and drag the start and end markers to your desired points. You can also type in exact timestamp numbers down to milliseconds. Click Play Selection to preview the exact audio excerpt before downloading.
Yes. For Android, select a 20 to 30 second snippet of your favorite song and export as MP3. For iPhones, trim a 30-second portion, export as M4R, and sync it to your iPhone. The cutter lets you apply a smooth fade in and fade out so the ringtone starts and ends naturally.
No. When trimming MP3, WAV, or AAC audio files, the browser decodes and slices the audio buffer directly in memory. When exporting as WAV (lossless) or high-bitrate 320 kbps MP3, all original sound dynamics and frequency ranges are preserved.
A zero-crossing point is the exact moment an audio waveform crosses the 0-amplitude center line. Slicing at a zero-crossing point prevents abrupt voltage jumps that produce audible clicking or popping artifacts in speakers and headphones.
