Frequently Asked Questions

Which audio formats can be trimmed?▼
MP3, WAV, OGG, and FLAC as input. Output format depends on the input type.
How precise is the trimming?▼
FFmpeg.wasm provides millisecond-accurate trimming. Specify exact HH:MM:SS.ms timestamps for frame-perfect cuts.
Is trimming lossless?▼
For WAV and FLAC, trimming is lossless. MP3 trimming requires re-encoding around cut points, resulting in minimal quality change.
Can I extract a specific segment from the middle of a track?▼
Yes. Set the start time to where you want the clip to begin and the end time to where it should end. Any segment can be extracted.
Is the processing done in the browser?▼
Yes. FFmpeg.wasm handles all trimming locally. Your audio file is never uploaded to any server.
