OPD (OmniPage document) file extension is being used in documents generated and/or saved using OmniPage scanning software. OmniPage is one of the pioneering programs in optical character recognition (OCR) mainstream. Launched by Caere Corporation in the early 80's, OmniPage was continuously developed to increase its adaptability to the changing trends in operating system. OmniPage is now part of the Nuance Communications and is supported by different PC platforms, including Windows 7 and Windows 8.
OPD file is a document file type that usually includes pictures, scanned images, texts and layout descriptions. By using OmniPage software, the user can easily go through the scanned files and edit them according to their preference.
The OPD file extension is also considered a proprietary file type that can only be accessed and modified using OmniPage programs. Editing documents in other OCR programs may not be possible since .opd files are DRM- protected.
