iText pdfOCR offers Optical Character Recognition functionality to convert your scanned documents, PDFs and images into fully ISO-compliant PDF or PDF/A-3u files making it possible to access and process the text they contain. The output can be configured to be text, a PDF consisting of separate layers for the source image data and a layer containing all recognized text, or as a flattened PDF with the layers merged.


  • Powered by the open-source Tesseract 4 engine
  • Simple, yet flexible API. It is also abstracted, to allow support for different OCR engines with little or no effort from users
  • Supports multiple input images (BMP, PNM, PNG, JFIF, JPEG or TIFF formats)
  • Text only extraction option: iText pdfOCR can recognize text in documents and export it as a text file. This can be used to populate external databases or with other tools.
