What is OCR PDF?

OCR, or optical character recognition, converts the text in an image into real characters a computer can read. A scanned PDF is just a picture of a page, so you cannot search it or copy its words. SuperPrompts' free OCR PDF tool recognizes the text on every page and produces a searchable PDF: the page looks exactly the same, but an invisible text layer sits on top, so search, select and copy all work. You can also download the recognized text as a plain .txt file. OCR supports 18 languages, including English, Spanish, French, German, Hindi, Arabic, Chinese and Japanese, and you can pick up to three per document. Recognition runs in your browser, so scanned documents stay on your device.
