I want to OCR a pdf to make it searchable.
Suppose you have a PDF document that was made using a scanner, or otherwise consists of image data but doesn't have text data. Such a PDF can't be searched by PDF readers or desktop search applications. pdfocr is a simple utility I made that takes a PDF file, then generates a new one that has the text layer added, so it's searchable by your PDF reader and can be indexed by your desktop search application, but is still identical when printed.
From Howto: Make scanned PDFs searchable (OCR) using pdfocr
Currenly, windows software like FreeOCR only makes a TXT file out of the pdf, but I want that original pdf only that it's searchable.
