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.

Renamer.ai vs Bulk Rename Utility:
Which Should You Choose?
If you've searched for bulk rename tools, you've probably seen Bulk Rename Utility (BRU). It's been around for years. It's free for personal use. And it's powerful - if you're willing to learn regex patterns and navigate its complex interface.

Differences Between Bulk Rename Utility and Renamer.ai
When Bulk Rename Utility Works
BRU is great if you need to add sequential numbers, change file extensions, or apply find-and-replace to filenames. It's a pattern-matching tool that does pattern-matching well.
But here's the fundamental limitation: Bulk Rename Utility 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.
The difference:
BRU: 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 themselveswhile 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
Bulk Rename
What Can You bulk rename?
Bulk Rename Photos
Stop scrolling through IMG_4521, IMG_4522, IMG_4523. Our AI identifies faces, locations, events, and objects. Your photos get names like "2024_Christmas_Dinner_Family_Portrait.jpg" - without you typing a single character.
Perfect for photographers, families with years of phone photos, and anyone drowning in unnamed image files.
Bulk Rename PDF Files
Got folders full of scanned documents, receipts, contracts, or invoices? Our AI reads the actual text inside each PDF and renames accordingly. "Scan0047.pdf" becomes "2024-11-20_Lease_Agreement_123_Main_St.pdf".
No more opening every PDF to remember what it is.
Batch Rename Documents
Word docs, Excel spreadsheets, presentations - we read the content and title them intelligently. Meeting notes get dates and topics. Spreadsheets get project names. Reports get identified by their actual subject matter.
No more manually typing dates, names, or project names.
