How precise is the trim?

Start and end times are set in seconds. The cut happens at the nearest frame boundary of the audio codec, which is precise enough for almost any use case.

Can I preview the trimmed section before saving?

Yes, play back your selected range before exporting to confirm it's exactly what you want.

Does trimming re-encode the whole file?

It processes just the selected range, keeping the process fast even for longer source files.

Does Trim Audio upload my files to a server?

No. Trim Audio runs entirely in your browser using on-device processing, your files never leave your device.
