Why OCR for Scanned PDF Files Matters
Scanned PDFs often contain pages that behave like images. You may be able to read the document on screen, but searching for a name, copying a paragraph, or locating a number can be difficult because the text is not digitally recognized.
Optical character recognition, commonly called OCR, identifies printed characters on scanned pages and adds usable text to the document. This makes records easier to search, review, organize, quote, and reuse in everyday study or office work.
