Online OCR extracts text from scans for free
Have you ever received a PDF file in an email that contained information you need in text form, but the PDF doesn't let you select the text? Sometimes this is due to access restrictions on the document, but more often it's because the person creating the PDF did so by simply scanning the document. This creates an image of the document, but does not embed the text information.
To extract the text, you need to use optical character recognition (OCR) software. Most scanners come with OCR software, but if you don't have ready access to it, you might consider using the Online OCR service.
Online OCR lets you upload a PDF file and it returns plain text that can then be copied directly into the word processing tool of your choice.
Obviously there are security concerns with uploading and storing copies of your documents on a 3rd party's site, but if that's not a concern to you, Online OCR might be just the trick to solve your OCR needs.
