A small change, a tidier collection

Make the names feel like they belong together.

Files gathered from different people or tools often arrive with different naming styles. Apply one consistent case without renaming each item by hand.

Choose a style that fits

Use lowercase, UPPERCASE, Title Case, Sentence case, camelCase, PascalCase, snake_case, or kebab-case.

Keep the file type intact

Change a file’s base name while preserving its final extension. Folder names are transformed as a whole.

Review larger batches

Enable a confirmation above your chosen item count. If a destination name conflicts, the item is skipped rather than replacing another file.

Your naming convention, one menu choice away.

Keep different Actions for different naming styles. Set a bulk-rename threshold to add a pause before a larger selection changes.

  • Eight case styles
  • Final file extensions stay intact
  • Optional bulk-rename confirmation

Good to know

This renames the original items. Conflicting names are skipped; the Action does not replace files or add sequential numbering.

Bring a little order to your filenames.

Apply your preferred naming case directly from Finder.
