Processing method
- Inventory the readable ID3 frames.
- Classify privacy-prone and core frames.
- Build a retained frame set that matches the visible rule.
- Export a new tag with the original MP3 audio bytes.
METADATA / PRIVACY PASS
Remove private fields and keep the useful tags visible.
Review the frames first, retain the core fields and artwork you need, and export a new MP3 without comments, encoder labels, URLs or custom text.
BROWSER-LOCAL / LIVE
Clean private metadata
Browser-local processing only. A new MP3 is always downloaded; your source is never overwritten.
METHOD / LIMITS / CHECK
The output rule should be as clear as the button.
Known limits
- Privacy classification is conservative, not a legal guarantee.
- Metadata outside supported ID3 boundaries cannot be certified as removed.
FAQ / TRUST
Answers that belong before file selection.
Does my audio leave this device?
No. The current workspace reads and processes the selected file in browser memory.
Will Sonelora overwrite my source?
No. Every change exports a new file; the selected source stays untouched.
