Frequently Asked Questions

Can I trim audio files too?

Yes. The tool supports both audio (MP3, WAV, OGG, FLAC) and video (MP4, WebM, MOV, AVI) files.

Is the trimmed file re-encoded?

When possible, the tool uses lossless cutting (no re-encoding) to preserve original quality. Some format combinations require re-encoding.

How precise is the trimming?

Precision depends on the format. MP4 can be cut to the nearest keyframe (typically within 0.5 seconds). Re-encoded output is frame-accurate.
