Which audio files can I trim?

Any audio file your browser can decode, including MP3, WAV, OGG, M4A and WebM audio.

How do I select the part to keep?

Drag the start and end sliders under the waveform, or type exact times in seconds in the number inputs.

The trimmed selection is exported as a 16-bit PCM WAV file, built entirely in your browser.

No. Everything happens locally with the Web Audio API. Your file never leaves your device.

The export is a 16-bit PCM WAV of the selected region at the original sample rate.

Your file is decoded and processed locally with the Web Audio API. Nothing is uploaded, so very large files depend only on your device memory.
