Renamer.ai uses AI and OCR to read the actual content of your documents and auto-generate clean, descriptive filenames. A messy invoice_scan.pdf becomes AcmeCorp_Invoice_$4,500_2024-03.pdf in seconds. Photos get described from visual content, so IMG_0421.jpg becomes Whiteboard_ProductRoadmap_Q2.jpg. Built for accounting firms processing invoices and receipts, law firms organizing contracts and case files, and HR teams managing employee documents. Batch process thousands of files in one pass. Available as desktop apps for Windows and macOS, a web app, and a developer API. Customizable templates match your filing convention. A browser-based option keeps sensitive files on your machine. Unlike rule-based tools like Advanced Renamer or Bulk Rename Utility, Renamer.ai reads what is inside each document, so it works on inconsistent scans and archives where filenames are useless. Free tier: 15 files/month. Paid plans from $9.95/mo. Try it at Renamer.ai.

Batch Rename Tool is made for users who need to rename multiple files quickly while keeping full control over the result. It provides a visual file list with a new-name preview, so users can review all filename changes before applying them. The software is useful for organizing photo folders, document archives, downloads, backups, scanned pages, work files, and other file collections. It supports common filename cleanup actions such as replacing text, inserting new text, removing unwanted characters, changing case, modifying extensions, and fixing number formatting with leading zeroes. Users can also create filename patterns using counters, dates, file information, folder names, and image dimensions.
