When a PDF file contains scanned pages or graphics that look like text, you can use OCR (Optical Character Recognition) text recovery to create an editable document.
Additionally, you can apply OCR to accurately recreate the text in a Word document when the font information in the PDF file is incomplete (resulting in corrupt or incorrect characters).
This converter uses SolidOCR for extracting text from scanned images.
OCR is dependent upon image quality, so we recommend a resolution of 200dpi or greater for best results.
If this option is selected then OCR will be performed on images only. This is usually the best choice. Any non-scanned text within the document will be extracted as text.
No attempt will be made to convert images to text. If you have selected to include images in the reconstructed document, then these images will still be images within the Word document.
The entire document will be considered to be a scanned image, even if it contains text. As such OCR will be performed on the text as well as the scanned image. This option is most useful if OCR has already been performed on the document, but failed to extract the text effectively, or the PDF contains "Non-Standard Encoded" text.
