PDF Rename is an extremely user-friendly application designed to automate the process of renaming PDF files using advanced OCR (Optical Character Recognition) technology. With a simple, intuitive interface, even non-technical users can batch rename PDFs in seconds. For power users and developers, a robust command-line version is also available.

3. The app scans each PDF, extracts relevant information (such as invoice numbers, dates, or custom fields), and renames the files accordingly.
