Cut songs and clips by start and end time with a waveform preview. Private Web Audio processing — export high-quality WAV.
MP3, WAV, M4A, OGG, or WebM — decoded with the Web Audio API.
Use the waveform and sliders. Preview the selection before export.
Sample-accurate cut exported as lossless PCM WAV for best quality.
Decode → slice AudioBuffer → encode WAV. No heavy ffmpeg.wasm download for a simple cut.
Cuts use sample indices from the decoded buffer, not crude re-recording.
Audio never leaves your device. Ideal for personal clips and demos.
Browsers cannot natively encode MP3 without a large LAME/ffmpeg library. WAV is lossless and universal; re-encode to MP3 locally if you need a smaller file.
Quick answers about tools, privacy, limits, and pricing.
Yes. Fair daily limits may apply for guests and free accounts.
True MP3 re-encoding in the browser needs a heavy encoder (LAME or ffmpeg.wasm). We use the best lightweight approach: precise cut + lossless WAV that every player and editor accepts. Convert to MP3 with your preferred desktop tool if required.
No. Decoding and cutting run entirely with the Web Audio API in your browser.
Anything your browser can decode — typically MP3, WAV, M4A/AAC, OGG, and WebM.
Yes. Use Play selection to hear only the start–end range.
The slice itself is sample-accurate on the decoded PCM. Original MP3 compression is already lossy; WAV export does not add another lossy pass.
