How to Rename Multiple Files at Once
(In 3 Simple Steps)
Most people searching "how to rename multiple files at once" expect complicated tutorials about command line scripts or regex patterns. Here's how it actually works with Renamer.ai:
Drop Your Files
Drag and drop any folder - or select specific files. We support 25+ file formats including PDFs, images, Word docs, and scanned documents.
AI Reads Your Content
This is what makes us different from every other bulk rename utility. Our AI actually opens each file and understands what's inside. An unlabeled PDF? We read it. A photo with no EXIF data? We see what's in it. A scanned document? We extract the text.
Smart Names, Instantly
Files are renamed based on their actual content - dates extracted from documents, people and places identified in photos, invoice numbers pulled from scans. What used to take hours takes minutes.

Which Should You Choose?
Ant Renamer is a free, open - source Windows tool for bulk renaming files and folders. It offers basic renaming features with EXIF and MP3 tag support but lacks content understanding.

Differences Between Ant Renamer and Renamer.ai
When Ant Renamer Works
Ant Renamer is a good free option for simple batch renaming tasks. It handles case changes, numbering, and basic metadata extraction from photos and MP3s.
But here's the fundamental limitation: Ant Renamer can only see filenames and metadata. It cannot read what's inside your files.
When You Need Renamer.ai
If your files are named Scan0001.pdf, IMG_4827.jpg, or Document(1).docx - and you need them named based on what's actually inside - pattern-matching tools can't help. You need AI that reads content.
Ant Renamer Limitations
- Windows only - no Mac support
- Cannot read document or image contents
- Limited to metadata and filename operations
- No AI or intelligent renaming
- Dated interface with limited modern features
The difference:
Ant Renamer: Scan0001.pdf → Scan0001_renamed.pdf (still useless)
Renamer.ai: Scan0001.pdf → 2024-03-15_Invoice_Acme-Corp_$2,450.pdf (actually findable)

Batch Rename Files on Any Platform
Windows 11 & Windows 10
Windows PowerShell can batch rename files - if you enjoy debugging scripts at midnight. Bulk Rename Utility offers more, but requires hours learning its interface.
Renamer.ai gives Windows users a drag-and-drop interface that bulk renames files based on content, not cryptic commands or regex patterns.
"I used to spend 20 minutes every day renaming downloaded invoices. Now I drop them in a Magic Folder and they rename themselves while I'm in meetings."Marcus T., IT Consultant
Mac OS
Mac's Finder has basic batch rename - sequential numbers, text replacement. Fine for photos from one shoot. Useless for mixed documents.
Renamer.ai for Mac reads each file's content, so your receipts, contracts, and scans all get meaningful names automatically. No Automator scripts. No Terminal commands.
"I handle hundreds of contracts and legal documents monthly. Renamer.ai reads the content and creates names like '2024-03-15_Acme_Corp_NDA_Signed.pdf' automatically. Saves me hours every week."Sarah M., Legal Assistant

Frequently Asked Questions
Is Ant Renamer still maintained?
Yes, but slowly. Version 2.13.0 shipped in December 2024, following version 2.12 from July 2015 - a roughly nine-year gap. The author, Antoine Potten, describes it on the project homepage as "an old project, started in 2003... still maintained to keep it running, but... based on old tools." It's not abandoned, but it's not under active feature development either.
Is Ant Renamer really free?
Yes - it's licensed under the GNU GPLv2, the source code is published, and there are no paid tiers. The project accepts donations but doesn't require them to use the software.
Can Ant Renamer rename scanned PDFs based on their content?
No. Ant Renamer works from filenames, EXIF tags, ID3 tags, and file dates - it never opens a document to read what's inside. Renamer.ai reads the scan's content directly and proposes a name from what it finds.
What does the GPLv2 license mean for Ant Renamer?
It means the source code is publicly available and you're free to use, inspect, and redistribute the software under GPLv2's terms. There's no license fee and no vendor lock-in, though it also means there's no commercial support contract behind it - support depends on the author's continued interest.
Is Ant Renamer an alternative to Renamer.ai, or a direct competitor?
It's a genuine alternative for a narrower job: free, offline, rule-based renaming on Windows, with no AI and no content reading. If you're choosing between the two, the honest split is scope - Ant Renamer handles filename patterns and embedded metadata well; renamer.ai handles the cases where the useful information is inside the document itself.
