Audio File Batch Renamer
Load audio filenames, edit track, title, and artist fields, preview pattern-based new names, and download a rename list without changing files on disk.
🔒 This tool runs entirely in your browser. Your files are never uploaded to a server.
Placeholders: {track}, {title}, {artist}, {ext}
| Original | Track | Title | Artist | New filename |
|---|
Example shown — upload your own files or edit the metadata fields.
How it works
- Upload a batch of audio files, or start with the sample rows.
- Edit each file's track number, title, and artist in the table.
- Set a filename pattern using placeholders — the new filename previews live for every file, ready to download as a rename list.
FAQ
Does it read real ID3 tags from my files?
It starts with a best-guess track number and title from each filename, which you can then edit directly in the table — full binary ID3 tag parsing isn't performed, so double-check and adjust the metadata fields for accurate results.
What placeholders can I use in the pattern?
Use {track}, {title}, {artist}, and {ext} anywhere in the pattern field — they're substituted per file. If you omit {ext}, the original file extension is appended automatically so files stay playable.
Does this rename files on my computer?
No — it generates a rename list (original name → new name) you download as a text file, since a browser tool can't rename files on your local disk directly. Use that list as a reference when renaming in your file manager or a batch-rename utility.
Pattern renamer vs. a dedicated tag editor
| Feature | This tool | Dedicated tag editor (e.g. Mp3tag) |
|---|---|---|
| No install, works instantly in browser | ✓ | ✗ |
| Reads/writes real embedded ID3 tags and renames files directly | ✗ | ✓ |
Great for planning and previewing a rename scheme quickly; for large libraries with real tag data, a dedicated tag editor will save time.
