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.

Features:

  • Powered by an ONNX compatible model (we're adding more as we go)
  • 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)
  • Supports PDF files as an input
  • 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.

Visit our knowledge base to find code samples, manuals, documentation, and more.

You can also find its API here.
