The Utified MP3 Cutter lets you trim any MP3, WAV, M4A, AAC, OGG, FLAC, or Opus file to the exact second — directly in your browser. Drag the handles on the waveform to set the start and end of the segment you want to keep, add a fade in or fade out to smooth the edges, and download a clean MP3 in one click.
Everything happens locally with the Web Audio API and the lamejs encoder. Your files never touch a server, so you can cut copyrighted music, voice memos, and personal recordings privately and instantly — no signup, no watermark, no upload progress bar.
What it is
An MP3 Cutter is a tool that trims an audio file to an exact start and end point. Utified MP3 Cutter does this with a visual waveform — drag the handles to pick the segment, add fade in / fade out, and export an MP3. Decoding and encoding run entirely in your browser, so files are never uploaded.

How to use it
Open your audio file
Drop an MP3, WAV, M4A, OGG, or FLAC file into the upload area — files up to 200 MB are decoded locally.
Drag to select the segment
Drag the two blue handles on the waveform to set the start and end. Press Space to preview just the selection.
Add fades or use a ringtone preset
Toggle fade in / fade out, or click the 15s / 30s / 40s / 60s buttons to snap the selection for a ringtone.
Cut and download
Click Cut & encode. The clip is rendered as an MP3 at the chosen bitrate and saved with a Download button.
100% client-side. Audio is decoded with the Web Audio API and encoded with lamejs locally — never uploaded.

Yes — completely free with no signup, watermark, or upload. The whole tool runs in your browser.
No. The file is decoded with the Web Audio API and encoded with lamejs entirely on your device. Nothing leaves your browser.
Anything the browser can decode: MP3, WAV, M4A, AAC, OGG, FLAC, Opus, and more. The output is always MP3.
Sample-accurate. The waveform handles snap to 0.01 second resolution, and the slice is performed on the decoded sample buffer — there is no re-encode of the part you keep, only the final MP3 write.
Yes — cut to 40 seconds or less with the 40s preset, optionally add a 2 second fade out, then convert the resulting MP3 to M4R with any MP3-to-M4R tool. The 40s limit and M4R format are iOS requirements.
200 MB. Above that, decoding can exhaust browser memory. Most songs and voice memos are well under this limit.
Yes. Toggle either fade, choose the duration in seconds, and the encoder applies a linear gain ramp to the start or end of your clip.
192 kbps is a good default for music. Use 128 kbps for voice or to save space. 256 or 320 kbps preserves the most fidelity but produces a larger file.
Yes, in any modern browser (Safari 14+, Chrome, Edge). Touch drag works on the waveform. Keyboard shortcuts need a connected keyboard.
Cut and download one clip, then re-select a different region from the same file and cut again — the original stays in the tool until you load a new file.
