OCR stands for
Optical Character Recognition. It is an advanced technology which allows
the computer to scan printed/written text and convert it to electronic
Literally all paper documents and
PDF documents can be scanned by OCR software, which turns these documents
into editable files, such as Word, Excel, etc.
Advanced OCR software also offers PDF
conversion capability. Document management using OCR scanning is
easy as piles of papers can be converted into compressed PDF files for
indexing or archive purpose within a short period of time. OCR
scanning for internet publishing is another application as data or
information on paper can be easily converted to HTML files.
Most OCR programs are usually
accurate in the mid 90% range so some proofreading and editing is
required. High accuracy means that the text and layout of the
document (including column, table, graphics) are kept as closed to the
original as possible. The higher the accuracy rate, the better the OCR
software is as it saves you time in proofreading and manual correction.
The speed of scanning and conversion, compatibility with popular PC
applications such as Microsoft Word, Excel, and the ability to adjust
the quality of scanned documents are other important factors in choosing a
good OCR program.
