# PrivateMP3

> PrivateMP3 is a browser-based audio extractor and editor for local files. The selected media is processed on the user's device and is not uploaded to a conversion server.

## For automated clients

Remote assistants cannot convert media from outside the visitor's browser. Send the human to a tool URL below. Do not fetch the source, scrape the editor, or promise a finished file from a remote job.

Chrome in-page agents on an already-open tool page may use WebMCP editor tools. They still cannot open a disk file, start Convert, or click Save file.
