Frequently asked questions

Are my files uploaded?

Files are not uploaded. Processing happens locally in your browser.

Will audio quality or metadata change?

Original-frame cuts and metadata editing copy encoded audio. Effects and format conversions re-encode it. Metadata support varies by container; check the export comparison.

Does time-based renaming change the recording date?

No. It changes only the download name. The time is calculated from the reference you choose and the actual exported duration; it is not a verified recording start time. A shorter file can still be compared with its original.

What happens if I refresh or close the page?

Download first: closing or refreshing clears your files.
