Bulk Rename Utility

What is Bulk Rename Utility?

Bulk Rename Utility is a free online tool for renaming files in batches. Nothing is uploaded and no software needs to be installed — everything runs in your browser. It offers two renaming modes:

• AI Mode: Describe the changes you want in plain language, and the AI generates the new file names.
• Rule Mode: Apply specific changes yourself, such as deleting or replacing characters, adding sequential numbers, building entirely new naming patterns, using regular expressions, or writing custom JavaScript for advanced renaming.

All operations happen locally on your device. The tool reads only your file directory, file names, and file sizes, so your files never leave your computer. It works on both Windows and Mac through the Chrome or Edge browser.
