Why Your Scanned PDF Needs OCR
When a document is scanned, your scanner photographs each page and saves the photo inside a PDF file. From the outside it looks like a normal document — but if you try to click on a word and nothing highlights, that's the giveaway. The file is just a picture.
OCR (Optical Character Recognition) fixes this by analyzing each pixel, recognizing letter shapes, and writing a real text layer into the PDF. The document looks identical after OCR — but now every word is searchable and selectable.
