A scanned PDF is essentially a photograph of a document. You cannot select words, copy sentences, or search for terms. OCR — Optical Character Recognition — solves this by converting the visual text into actual characters.
OCR adds a hidden searchable text layer underneath the scanned image. Here is how to apply it for free in seconds.
