METADATA / REPEATABLE BATCH

Apply one clear tag rule across a batch of MP3 files.

Select several MP3 files, choose which shared fields should change, review every filename, then export a new copy for each source.

BROWSER-LOCAL / LIVE
FILE BOUNDARYThe selected file enters browser memory only. There is no server upload path, and the source is never overwritten.

Batch edit ID3 tags

Browser-local processing only. A new MP3 is always downloaded; your source is never overwritten.

Core fields

A filled value replaces that field in every file; an empty value keeps each file’s existing value.

0 / 6

METHOD / LIMITS / CHECK

The output rule should be as clear as the button.

01

Processing method

  1. Read every selected MP3 before enabling export.
  2. Apply only non-empty shared fields.
  3. Keep each file’s unchanged core fields where no override is supplied.
  4. Download individually named output copies.
02

Known limits

  • Browser download settings may ask permission for multiple files.
  • The batch remains in memory; very large selections are rejected.

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.
