How to Process a PDF Image Through OCR
OCR is actually an abbreviation for Optical Character Recognition. This type of software is used mostly for converting scanned images of text data and handwriting into any of the popular document formats to get in return, raw text data. OCR not only converts scanned images but also handwriting. Handwriting recognition is a sub module within OCR software which are available both online and offline. Handwritten scanned images can be processed through an OCR software or service online and get in return, machine readable text files in any of the major document formats including PDF.
How to Find OCR Services Online to Convert to PDF Images
A search engine would be most ideal to look for and find an appropriate online OCR service which would offer the total features of an offline software based OCR system completely online without the hassles of an installation onto the PC. Most online OCR services offer all the features that a software module would offer upon full installation onto a PC. Web based OCR services are also of two types, one being an open source version and the other being a commercial version. The commercial as well as the open source OCR services online would require a user to upload the PDF file in need of an OCR session. The quality of PDF documents prepared using the OCR services online would almost be the same as from the installed software on the PC offline.
The Pros and Cons of Online OCR Services to Convert PDF Image Files
The one big positivity about online OCR services is the accessibility. A user can access the online OCR service anywhere there is a reliable network offering the Internet. A user could simply upload a scanned image or a PDF image with either printed or handwritten data and inturn process the file to receive a copy of the file in any of the pre-chosen document formats. The only con is that the network has to be a fast and reliable one. A network that is compromising on data transfer times due to slow bandwidth would totally hinder the usability of a good online OCR site while converting PDF images. Hence looking for a wider bandwidth network before uploading PDF images or scanned image files is wise.
