This error happens because OCR is designed for pages that are only images. If a page already has real, selectable text, Acrobat cannot apply OCR to it. OCR only works to convert image-based text into a searchable layer, not to re-process existing text. You should check if the page is truly an image before running OCR.
OCR, or Optical Character Recognition, is a technology that turns images of text into actual, selectable text. It's important for scanned documents because most scans are just pictures. OCR makes these pictures searchable, so you can find specific words, copy text, and interact with the document content, which is very useful for archiving and data retrieval.
