What is Bulk Rename Utility?

AI Bulk Rename Utility is a web‑based solution that processes file names locally, using AI to interpret natural‑language instructions and apply batch renaming, sequential numbering, or pattern rules without uploading data. It supports Windows, macOS, and browsers that implement the File System Access API, making it suitable for developers, office staff, and photographers who need quick, accurate renaming of large collections.

The AI mode automatically detects context, while the rule mode offers regex and JavaScript customization for advanced users. A built‑in photo renamer tags images by date, event, or sequence, helping photographers keep albums organized. The interface includes preview and instant execution, allowing users to verify changes before applying them.
