How to install pdfOCR .NET version

Thank you for your interest in our OCR add-on - pdfOCR, we hope you will enjoy using our product and share your experiences with us and the iText community. We will walk you through the installation process, from downloading iText pdfOCR to adding the dependency to your .NET build tool.

If you require any extra help please have a look at our FAQs or the community discussion at StackOverflow. If you are interested in getting support from our in-house developers and/or a license key for commercial iText products, you will need to acquire a commercial license.

Before you install

  • If you want to use pdfOCR for non-commercial purposes, make sure you have read and agreed upon the AGPL license. All downloads we offer open-source come with the AGPL license model.
  • If you want to use pdfOCR for commercial purposes, make sure you have purchased a commercial license of iText Core and pdfOCR. All downloads we offer closed-source come with our commercial license model.
  • For closed-source pdfOCR installation, download and install the proper license key library, you can find the installation guide here (you will need at least version 3.1.1 of the library).
  • Check the compatibility matrix to ensure the version you specify when adding the add-on's dependency matches the version of iText Core you have a license for.

  • Install iText Core or Community, you can find the installation guide here.
  • Important remark: in the installation guide we use NuGet as a build tool for .NET.
  • You will need Tesseract's training data, which you can get here.
