Batch File Renamer: Rename
Multiple Files at Once

The best batch file rename tool is one that reads your documents, not just their filenames. renamer.ai uses AI to analyze invoices, contracts, and photos—extracting vendor names, dates, amounts, and key details to create meaningful filenames automatically. Unlike basic bulk rename utilities that only add prefixes or sequential numbers, our tool understands what's inside each file.

With renamer.ai, our mass file renamer handles bulk file rename in four simple steps: (1) Drop your files into the app—invoices, contracts, photos, anything. (2) Pick a template like Invoice or Contract, or describe what you want in plain English. (3) Preview every new filename before committing. (4) Click rename—hundreds of files renamed in seconds. No regex, no complex patterns.

Download renamer.ai for Windows or Mac—it installs in under a minute. Unlike built-in tools that require memorizing commands or patterns, our batch rename tool lets you describe what you want in plain English. 'Name these by vendor and date' or 'add invoice numbers from inside each PDF.' The AI handles the rest. Works identically on both platforms.

Our mass file renamer uses AI to read what's inside each document—not just the filename. Drop your files, and the AI extracts key information like vendor names, invoice numbers, dates, and amounts from PDFs, scanned documents, and images. Then it automatically generates descriptive filenames based on that content. No manual data entry, no opening files one by one.

Yes - our PDF renamer reads inside every document automatically. It extracts vendor names, invoice numbers, dates, amounts, contract parties, and more. Drop 400 invoices named 'Scan_001.pdf' and get back 'Acme_Corp_Invoice_2024-03-15_$4250.pdf' - all without opening a single file yourself.

Absolutely. Our photo renamer uses AI vision to analyze each image and rename intelligently. Product photos get named by item and angle. Event shots by date and subject. Marketing images by campaign. Drop 2,000 photos named IMG_0001.jpg and get back organized, searchable filenames in minutes.

Our AI uses advanced OCR and document analysis to instantly extract text, dates, vendor names, amounts, and key information from inside your files. PDFs, scanned images, photos of documents - if there's text visible, we read it and understand it.

You approve every single rename before it happens. Spot an error? Edit that file individually, refine your instructions, or exclude it from the batch. Nothing changes until you're 100% satisfied with the preview.

Absolutely. One click restores all original filenames instantly. We maintain a complete history of every rename operation, so you can always go back - no matter when you change your mind.

Your files are processed securely and never stored. Once renaming is complete, file data is immediately discarded. We don't keep copies, build profiles, or share anything. Your documents remain yours alone.

Our batch file rename tool supports all common document and image formats—PDFs, Word docs, Excel spreadsheets, PowerPoint, images (PNG, JPG, HEIC, WebP), and more. Over 25 supported formats covering everything accountants, legal teams, and HR departments use daily. Bulk rename all files in a folder regardless of type, or filter by specific formats.

Each plan includes a generous monthly allowance - from 15 files on Free up to 5,000 on Ultimate. Within a single batch, you can process hundreds of files at once with instant results.

You'll catch it in the preview before any damage is done. Edit individual results, tweak your instructions, or exclude specific files from the batch. Full control, zero risk.

Download the app - it installs in under a minute with zero configuration. Open it, drop your files, and start renaming immediately. Works on Windows and Mac.
