Files & Archives · Batch Rename
Rename many files at once on your computer, with a full preview
Quick answer
Add files to Toolfox → Batch Rename and build names with find & replace (or regex), prefixes, suffixes, numbering and patterns like “Trip {n} {name}”. A live preview flags every conflict, and nothing changes until you confirm. It runs entirely on your computer (Mac, Windows or Linux). Files are never uploaded.
How to do it
- Open Batch Rename and add files.
- Set rules: pattern, find & replace, prefix/suffix, numbering, letter case.
- Check the preview. Conflicts are highlighted.
- Click Rename and confirm. If anything fails, names are rolled back.

Good to know
- Nothing changes until you review the preview and confirm.
- Collisions and existing files block the rename. If a rename fails midway, completed renames are rolled back.
Batch Rename FAQ
Can I undo a batch rename?
If a rename fails midway, Toolfox automatically restores the original names. After a successful rename, run it again with the reverse rule.
Does it handle names that only differ by case?
Yes. It detects collisions the way APFS does (case- and Unicode-insensitive).
Is Batch Rename in Toolfox free?
Yes. Batch Rename is one of 57 tools in Toolfox, a free app for Mac, Windows and Linux with no account, ads, limits or watermarks.
Does Batch Rename upload my files?
No. Toolfox processes files on your own computer and works offline; your files are never uploaded.
