Intro

iText pdfOCR

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. 

Every day we receive scanned documents or images containing printed text in huge amounts. But without machine-readable text, the content cannot be edited, searched, indexed or processed.

Benefits

Why use iText pdfOCR?

One of the major challenges in document management is dealing with inaccessible data, data which is locked away in non-editable documents. Scanning a document containing printed text does not make it editable or searchable however, you just have a scanned image of the content.

Optical Character Recognition (OCR) can help to unlock this data. One of the most common use cases for OCR is to produce documents which can be searched, processed, or archived. While some word processing and PDF applications now offer OCR functionality to make PDFs editable, manually doing this for more than a few documents is impractical.

iText pdfOCR provides a way to automate the OCR process, and integrate it into document workflows.

  • Securely redact recognized text with iText pdfSweep
  • Use extracted text to populate PDF form fields using iText Core
  • Merge text into HTML templates for iText pdfHTML conversion to PDF.
  • Use recognized text with iText DITO and add data binding and conditional formatting to PDF templates.
Key features

Core capabilities of pdfOCR

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. If you need documents to be suitable for long-term archive storage, then the support for PDF/A-3u output is an added bonus.
