What is OCR (Optical Character Recognition)?
Optical Character Recognition (OCR) is a visual recognition process that turns
printed or written text into an electronic character-based file. A document that
is scanned and converted into a PDF document provides the basis for which
character recognition software may interpret each character image on the PDF and
assign it an electronic character-based file that can then be entered into an
editable format, such as a Text or Word document.
Given the proliferation of scan-to-PDF technology available today, VeryPDF's OCR
solutions focus on the conversion of scanned PDF documents and image files. The
quality of the OCR conversion process will largely depend on the quality of the
scanned image and the clarity of the characters of that image.

Optical Character Recognition technology to OCR scanned PDF documents and images
(TIFF, BMP, PNG, JPG, PCX, TGA, etc.) to OpenOffice files.
