Chances are, someone else is already bald and figured it out. We show you all the tricks. Read More , but there are also easy ways to do this on a Mac.

Back in the day, you had to select each individual file, press Enter, and select the part of the filename to rename, or retype the whole thing. Now, you can do fancy tricks when renaming multiple files, like replace text in filenames, add numbers or other text to the beginning or end of filenames, or remove text from filenames.

There are several ways to batch rename multiple files on your Mac. Today we look at using the Rename feature in Finder, creating an Automator workflow, and using a free app called NameChanger to rename multiple files.

Batch Renaming Multiple Files Using Finder

Finder now includes a very useful Rename tool. You can replace text in a filename, add text before or after the current name, or choose a new name format and add an index, counter, or date before or after that name.

Selecting Files to Rename

To use the Rename tool in Finder, open the folder in Finder containing the files you want to rename and select them.

Next, press Control and click on the selected files. Select Rename X Items from the popup menu. The “X” indicates the number of files that are selected to rename.

Replacing Text in Filenames

On the Rename Finder Items popup window, you can choose to replace text in the names, add text to the names, or change the name format.

First, we’ll look at replacing text, so select Replace Text from the dropdown list.

Enter the text you want to replace in the Find box. Then, enter the text you want to add in its place in the Replace with box. You can use this method to remove text from filenames. Simply leave the Replace with box blank. The Example preview shows you how the filenames will look after renaming. Click Rename.

Adding Text to the Beginning or End of Filenames

To add text to filenames, select Add Text from the dropdown list on the Rename Finder Items dialog box.

Enter the text you want to add and then select whether you want to add the text before or after the name. Then, click Rename.

Replacing the Name and Adding an Index, Counter, or Date

If you want to name many files with the same name and add an index or date to the names, select Format from the drop-down list on the Rename Finder Items dialog box.

Select an option from the Name Format dropdown list to indicate whether you want to add an Index, a Counter, or a Date to the name. Then, select after name or before name from the Where dropdown list.

Next, enter the text you want to use for each filename in the Custom Format box. If you selected Name and Index or Name and Counter from the Name Format dropdown list, enter the number you want to start from in the Start numbers at box. For the Name and Date option, you only get one date format.

An example of how the filenames will look once they’re renamed displays below the Custom Format box. If you leave the Custom Format box blank, a space and the Index, Counter, or Date will be added after the current name.

Undoing the Rename Process in Finder

To reverse the changes and go back to the previous filenames, go to Edit > Undo Rename in Finder.

Selecting a Rename Method

The dropdown list in the middle of the bar above the file list provides various methods for renaming files. Select the one you want. For our example, we’re going to use the Wildcard method. This allows us to use the asterisk (*) and question mark (?) to indicate text to be replaced.

Use the asterisk to replace all the text and the question mark to replace a single character. For example, we want to replace the entire filename, so we enter “*.jpg” in the box on the left. Then, we enter the text we want to replace it with in the box on the right. Numbers are automatically added to the filenames.

The right column shows how the filenames will change when you rename the files. Click Rename on the toolbar to rename the files as specified.

Adding Sequential Numbers to Filenames

Use the Sequence method to add sequential numbers to the beginning (Prepend) or end (Append) of the filenames.

If you didn’t turn on the Hide extensions by default option in the Preferences, you can also hide them by going to Options > Hide Extensions.
