Make a Scanned PDF Searchable

A scanned PDF is a stack of pictures: you can read it, but you cannot search it, highlight a sentence or copy a paragraph. This tool reads each scanned page with OCR (Tesseract) and lays the words it finds, invisibly, over the picture. You get the same document back, looking exactly as it did, but now Ctrl+F, selection and screen readers work.

Worth knowing

OCR reads printed text well and handwriting poorly, and it can misread small, faint or skewed print, so search may miss the odd word. Up to 40 scanned pages are read per job; pages that already have text are skipped and do not count. Pages scanned sideways should be turned upright first with Rotate PDF.
