Batch rename files on your Mac
Toolbox renames a whole folder of files in one go. You can replace text (with optional regular expressions), add text before or after the name, number files in order, add their creation or modified date, or change the case. A live preview shows every new name before anything changes, and Undo puts them back.
How to use Batch Rename
Open Batch Rename and drop files or folders onto the window.
Choose a mode: Replace Text, Add Text, Format or Change Case, and set its options.
Check the preview, and sort the list by name or date if the order matters.
Click Rename. Use Undo if the result isn't what you wanted.
Questions about Batch Rename
How do I rename multiple files at once on a Mac?
Finder can rename a selection with its Rename command, but it offers few options and no regex. Batch Rename adds regular expressions, date-based names, sorting and a full preview before you commit.
How do I number files in order on a Mac?
Choose Format, then Name and Number, and pick a separator. Sort the list by name, date created or date modified first so the numbers follow the order you want.
Can I rename photos by the date they were taken?
Batch Rename can use the file's Date Created, Date Modified or today's date. It does not read camera EXIF data, so Date Created reflects when the file was made on disk.
Can I undo a batch rename?
Yes. After renaming, click Undo to restore the original names.
