OCR
The Conversion Service can be used with your existing 3-Heights® PDF OCR Service service configuration.
A single instance of the 3-Heights® OCR Service can be used by the Conversion Service and other products like the 3-Heights® Document Converter at the same time.
The 3-Heights® OCR Service enhances PDF documents using information an OCR engine detects. The optical character recognition (OCR) technology identifies characters in images, scanned documents, and documents containing images with text. It adds a text layer containing recognized characters without visual changes to the original documents. The OCR enables you to make all text extractable.
The 3-Heights® OCR Service is no longer maintained. We recommend configuring the OCR engine directly in the Conversion Service without the OCR Service for new installations. For details about the recommended configuration of the OCR engine through the Conversion Service, see Configure OCR documentation.
Configure 3-Heights® OCR Service in the Conversion Service
You can activate OCR processing for the archive and conversion workflows. The 3-Heights® PDF OCR Service must be configured and accessible through HTTP.
The following steps explain how to activate and configure OCR in a profile:
- In the Conversion Service Configurator, go to Workflows & Profiles.

- Select 3-Heights® OCR Service as the OCR engine, and then click Next.

You can configure multiple 3-Heights® OCR Services to distribute the OCR processing equally.
