How it works
Three steps, start to finish.
-
01
Open Batch Rename
Press ⌃⌥Space and type “bulk rename”, or pick it from MightyBench’s menu bar icon.
-
02
Add files, pick a mode
Drop files of any type and choose Name & Number, Find & Replace, Add Text or Change Case. Set Start at for numbering and check the live preview.
-
03
Press Rename
Renamed copies land in a new dated folder in Downloads › MightyBench. Turn on Rename originals to rename the files where they are instead.
The details
Small things, done properly.
-
See every name first
A live preview shows every new name before a single file changes, so you can adjust the pattern until it’s right.
-
File-09 before File-10
Numbers are zero-padded, so File-09 sorts before File-10 in Finder and in any list sorted by name.
-
All or nothing in place
Renaming originals checks for name clashes first and rolls everything back if a single rename fails.
-
Extensions always kept
Only the name changes. A .jpg stays a .jpg and a .pdf stays a .pdf, whichever mode you use.
-
Copies, or in place
Leave Rename originals off for renamed copies in Downloads › MightyBench, or switch it on to rename the files where they are.
-
Four ways to rename
Name & Number, Find & Replace, Add Text and Change Case cover numbering a shoot, fixing a typo or tidying capitals.

FAQ
Questions about Batch Rename
Anything else? Email support@mightybench.com and a person will reply.
How do I rename multiple files at once on a Mac?
Open Batch Rename, drop the files in and pick a mode such as Name & Number. Check the live preview, press Rename, and renamed copies appear in a new dated folder in Downloads › MightyBench.
Can I rename the original files instead of copies?
Yes. Turn on Rename originals and the files are renamed where they are. MightyBench checks for name clashes first and rolls everything back if one rename fails.
Will it change my file extensions?
No. Extensions are always kept, so a .jpg stays a .jpg and a .pdf stays a .pdf.
How do I number files so they sort in the right order?
Choose Name & Number and set Start at. Numbers are zero-padded, so File-09 sorts before File-10.
Can I find and replace text in file names?
Yes. Choose Find & Replace and the live preview shows the new name for every file before you press Rename.
Does it work with any type of file?
Yes. Batch Rename takes any file type, from photos and PDFs to audio and documents, and always keeps each extension.
