What it does
Preview first
Every rename shows the old name beside the new one. Nothing changes until you press Apply.
Undo any batch
Each batch is kept in a history, so you can put the old names back even days later.
The usual tools
Find and replace, add a prefix or suffix, remove or trim characters, and change upper or lower case.
Free edit
Click any name and type, right where you clicked, like renaming in Finder.
AI clean
Removes the AI labels and Content Credentials that Photoshop and Lightroom add to JPEGs. The picture itself isn't touched, and it can be undone.
Works from Finder
Right-click files in Finder to open them in Renamer, or add it to the Finder toolbar to open the folder you're in.
What it looks like
Every new name is shown beside the old one. Nothing changes until you press Apply.
Install
- Download Renamer.zip and double-click it to unzip.
- Drag Renamer into your Applications folder.
- Open it. macOS will say it can't check the app, because it doesn't come from the App Store or a registered developer yet. Click Done.
- Open System Settings › Privacy & Security, scroll down to the line about Renamer and click Open Anyway. You only have to do this once.
If macOS still won't open it, run this once in Terminal, then open Renamer again:
xattr -dr com.apple.quarantine /Applications/Renamer.app
Private by design
Renamer runs entirely on your Mac, in its own window. No account, no upload, nothing sent anywhere. It only goes online when you click Check for updates in Settings.
