This tool uses FFmpeg compiled to WebAssembly to cut the selected range without re-encoding the audio - a 'stream copy' operation that's both fast and lossless within the cut region, since no audio data in your selection is touched.
Frequently asked questions
4 questionsNo - trimming uses a fast stream copy rather than re-encoding, so the audio inside your selected range is untouched. For compressed formats like MP3, the exact cut point can land up to one frame (a few milliseconds) off due to how those formats are structured; for WAV it's sample-accurate.
