Download. Cuts are frame-accurate copies of the original; conversions use the LAME MP3 encoder in your browser.
About this tool
Set start and end in seconds and the tool copies the original frames between them. An MP3 cut lands on a frame boundary (about 26 ms), which is inaudible for speech and music. Because there is no decoding, files of any length work, and the result is always smaller than the source. Drop a video to cut a piece of its soundtrack.
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.
