Frequently Asked Questions

Can I split an MP3 without re-encoding?

Yes. When the output format matches the input (MP3 → MP3), the tool uses FFmpeg's stream copy mode (`-c copy`). There's no decoding or re-encoding, so the audio is bit-identical to the original and processing is near-instant.

How do I split an MP3 album into separate tracks?

Use Tracklist mode. Paste your tracklist in the format `timestamp Track Name` — one track per line. Each segment in the ZIP will be named after its track (e.g. `01-Intro.mp3`, `02-Chorus.mp3`). It accepts most common tracklist formats, including numbered lists and bracketed timestamps.

What's the maximum MP3 file size?

Up to 10 GB on paid plans. All processing happens locally on our server — nothing is uploaded to third parties. Files are deleted automatically after 24 hours (3 days for paid plans).

Will the cuts be precise?

Cuts land on the nearest MP3 frame boundary, typically within 20–30 ms. For music this is effectively seamless. For sample-accurate cuts, use WAV or FLAC output instead.
