How it works
- 01
Drop an audio file — or a video, if you only want its sound.
- 02
Pick the range or the target format.
- 03
Download. Cuts are frame-accurate copies of the original; conversions use the LAME MP3 encoder in your browser.
About this tool
MP3 encoding uses a WebAssembly build of LAME running in your browser; other targets use the encoders your browser ships. Keep the source sample rate unless a device requires otherwise, and choose 192 kbps or higher for music. Video files are accepted too — the audio track is converted and the picture discarded.
Questions
- Does trimming an MP3 lose quality?
- No. The cut copies the original frames; nothing is decoded or re-encoded, so the file can only get smaller.
- What can I convert to?
- MP3, WAV, M4A, OGG (Opus) and FLAC. The menu only lists what your browser can actually encode.
- Can I use very long recordings?
- Yes for cutting — any length. Conversions of multi-hour files depend on device memory.
