How to install pdfOCR Java 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 7 pdfOCR to adding the dependency to your Java 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-sourcce come with the AGPL license model.
  • If you want to use pdfOCR for commercial purposes, make sure you have purchased a commercial license for iText 7 Core. 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).
  • Download the modules (.jar) of iText 7 Core/Community and pdfOCR (ZIP files) from Maven Central or the iText Artifactory Server.
  • Install iText 7 Core or Community, you can find the installation guide here.
  • Important remark: in the installation guide we use Maven as build tool for Java.
  • You will need Tesseract's training data, which you can get here.

Installation

Using the Central Repository

iText 7 pdfOCR is available via Maven on The Central repository. Simply add iText 7 pdfOCR as a dependency to your pom.xml:

Using the iText Artifactory Server

iText 7 pdfOCR is also available on the iText Artifactory server. Here you can also find the license key library, and pdfOCR add-on - you require an additional license key if you want to use pdfOCR closed-source (commercial purposes).
