What is Bulk Rename Utility?
AI Bulk Rename Utility is an intelligent web-based file renaming tool powered by advanced AI technology that enables smart batch renaming, file organization, and photo management for both Windows and Mac users. The tool processes everything directly in your browser with 100% client-side processing, meaning your files never leave your computer and no uploads are required - it only reads file names. Users can import files or folders, choose between AI Mode for natural language input or Rule Mode for precise control with regex and JavaScript support, and then preview changes before executing renaming with one click.
Key features include AI-powered intelligence that understands plain English descriptions for renaming needs, smart pattern detection, and the ability to handle complex renaming rules automatically. The utility offers specialized tools like AI File Organizer for automatically categorizing messy folders based on natural language descriptions, and Photo Renamer specialized for photographers to rename photos by date, event, or sequence. Basic capabilities include adding/replacing/inserting text, converting case, auto-numbering, appending dates in multiple formats, and filtering files using wildcards, regex, or JavaScript conditions.
This tool is ideal for anyone who needs to rename multiple files quickly - from individual users organizing personal photo collections and documents to professionals managing large file libraries. Photographers can rename holiday pictures from meaningless names like dsc1790.jpg to meaningful names like NewYork1.jpg using EXIF metadata. The freemodel makes it accessible without installation requirements, while the privacy-focused local processing appeals to users concerned about cloud-based file uploads. It handles folders with over 100,000 entries and can batch rename thousands of files in seconds.
The utility also supports advanced features like directory recursion for processing sub-directories, renaming MP3 files using ID3 tags, using Windows File Properties for media attributes (length, width, height, rate), changing file timestamps and attributes, creating undo batch files, and logging all renaming activity. Users can save renaming criteria as favorites, sort file details by any column, and add

Frequently asked questions about Bulk Rename Utility
How to Use Bulk Rename Utility?
Select files or folders by importing them, choose between AI Mode for natural language input or Rule Mode for precise control with regex/JavaScript, then preview the changes and execute the renaming with one click. No file upload is needed - the tool only reads file names and processes everything locally in your browser.
Is it free?
Yes, it's a free online tool with daily limits of 2 renames per day and 50 files per rename operation. No downloads or installations are required. You can refill your daily AI renames, and the tool requires no credit card or registration for the free tier.
Which browsers are supported?
The tool is optimized for Chrome and Edge browsers due to their File System Access API support. These browsers provide the best experience for importing files and accessing the local file system directly.
Is my data safe?
Yes, all operations happen locally on your device in your browser. No files are ever uploaded to any server, no data is stored on any server, and only file names are processed. This provides 100% privacy protection compared to cloud-based tools that require file uploads.
What is AI Mode vs Rule Mode?
AI Mode allows you to describe your renaming needs in plain English, and the AI understands your intent and applies changes automatically with smart pattern detection. Rule Mode provides precise control using Regular Expressions (regex) or JavaScript for users who need exact, custom renaming rules.
Can I rename photos with this tool?
Yes, there's a specialized Photo Renamer tool for photographers to rename photos by date, event, or sequence. The utility can also rename photos using EXIF metadata like 'Date Picture Taken' and 'Resolution' that are embedded in JPG photo files, letting you rename holiday pictures from meaningless names to meaningful event-based names.
What file types can I rename?
The tool can rename any file type, with special capabilities for JPG photos (using EXIF metadata), MP3 files (using ID3 tags), and media video files (using Windows File Properties like length, width, height, rate). It handles documents, images, audio, video, and any other file formats.
Can I process subdirectories?
Yes, the utility supports directory recursion which processes files and folders in all sub-directories too. This means you can rename files throughout an entire folder structure including all nested subfolders in one operation.
How do I save my renaming preferences?
You can save your renaming criteria into favorites for quick reuse later. This lets you store complex renaming rules (regex patterns, JavaScript code, or specific text operations) and apply them again without having to recreate them each time.
Can I undo a renaming operation?
Yes, the utility can create an undo batch file that allows you to reverse renaming operations. This provides a safety mechanism if you need to revert files to their original names after a renaming operation.
