Frequently Asked Questions

How precise are the start/end times?

To 1-second precision via stream-copy. For frame-accurate trimming, use the Trim Media tool which re-encodes.

Will trimming reduce audio quality?

No — we use stream-copy mode which preserves the original bytes. The trimmed file is identical quality to the source.

What format does it output?

Same format as input. Trim an MP3 → get an MP3. Trim a FLAC → get a FLAC. No re-encoding.
