Get in on the details that matter

Do you need to inspect your PDF on the details that matter? iText’s Reading and Updating PDF Syntax (RUPS) is here to help. RUPS, built upon iText Core, offers a crystal-clear look on how a PDF is constructed. It allows developers to understand a PDF file’s different objects and content streams, resulting in faster debugging and fixing.

PDF inspection made easy

RUPS is a tool for developers by developers, originating in our labs as an internal diagnostics tool. We would have been amiss not to offer its practical functionalities to our customers. In addition, you can use RUPS for:

  • Internal dictionary content inspection of your PDF

  • XObject examination to check for filesize inflation

  • Standardization check for PDF syntax or XFA technology

  • Debugging PDF documents
