Creating searchable PDF files using optical character recognition is one of the most common PDF OCR applications.
The PDF format works great with scanned documents because it allows the OCR text to be hidden in an invisible layer behind the original document image. So you see a perfect replica of the original instead of OCR text that lacks formatting and may contain artifacts and errors.
PDF OCR can also mean converting scanned PDF files to Word, Excel, text and other formats. This can be done with any desktop OCR or OCR server application. However there are several OCR applications called PDF Converters that are only designed to convert documents to searchable PDF files rather than converting PDF files to other formats. This is an important distinction to make when searching for PDF OCR software.
PDF Converters often cost less than their full-featured desktop OCR counterparts since they only offer document scanning and conversion of images to searchable PDF files. They can also include the ability to convert other file formats like Word, Excel, PowerPoint, HTML, etc. to PDF automatically. Enterprise site licensing options let you enable this capability for any user in the organization. Contact us for a quote on site licenses for any PDF OCR application.
PDF OCR Compression
PDF also offers advanced compression options like MRC, JPEG2000 and JBIG that can produce much smaller files than traditional TIFF images. Foxit PDF Compressor is even able to parse the document and apply different compression to images, text and backgrounds to reduce the size even further. This can produce huge savings in cloud storage and access charges when archiving millions of pages of documents.
Automatic Sorting and Indexing for PDF OCR Documents
Simple Software’s SimpleIndex application takes PDF OCR to the next level by adding advanced pattern matching, data extraction and database integration capabilities to assign metadata tags and search keywords to PDF documents. These indexes can be used to automatically organize them into folders and filenames, attach to records in a database, or upload to a web service application, document management system, or cloud storage. SimpleIndex can OCR scanned images to searchable PDF files, and it can process native, digital born PDF files without OCR.

Foxit PDF Compressor is an OCR server equipped with enhanced compression that can dramatically reduce the size of PDF files. This can lead to big cost savings in cloud storage and bandwidth fees, and improved efficiency for knowledge workers who save time on every file they open.
PDF Compressor uses the OmniPage OCR engine, proving incredibly fast recognition speeds and high accuracy in over 200 recognition languages.
PDF Compressor intelligently applies MRC, JPEG2000 and JBIG compression algorithms to the parts of the document that can achieve the biggest reduction from each. Color images, text and backgrounds are separated and compressed individually. Other OCR applications will only apply one compression type for the whole document, which can reduce the quality of mixed documents while it fails to achieve optimal compression.
