You open a scanned PDF, try to search for a word — and nothing happens. You try to copy a sentence, and you can’t select anything. That’s because a scan is really a pictureof text, not text itself. OCR fixes that. Here’s how to make a scanned PDF searchable, free.

What OCR actually does

OCR — optical character recognition — reads the letters inside the scanned image and adds an invisible text layer behind the page. The document looks exactly the same, but now you can search, select, and copy the text like any normal PDF.

Why it’s worth doing

  • Searchable archives — find any document by its contents, not just its filename.
  • Copy-paste — reuse text instead of retyping it.
  • Better conversions — OCR first, then convert to Word for a truly editable file.
