What is OCR software for PDF? Explained

With optical character recognition (OCR) technology, OCR software automatically extracts text from any scanned PDF or image file and OCR converts it to a searchable PDF file. With OCR software, you can transform a scanned PDF of a paper document into a text-searchable PDF document. This new OCR searchable PDF is like an image containing text data, that you will be able to search for a specific keyword. When we read a document, our brain recognizes a character by analyzing the patterns and compare them against the pre-learned alphabet set. An OCR software application is trying to do the exact same. An OCR software reads the text pixels from a scanned image and compares it against a pre-trained dataset. Once the text is recognized, it is added as a hidden layer in the scanned PDF. This new "sandwiched PDF" file is popularly known as a searchable PDF.

what is "searchable PDF"? Explained

Wednesday, October 2, 2019

A scanned PDF is not text searchable. It is mainly because a scanned PDF is an image of a text document embedded in a PDF. There is no character or other text information in that PDF document. A scanned PDF has to go through Optical Character Recognition (OCR) in order to make this PDF text searchable. You need the help of PDF OCR software to convert this scanned PDF to a searchable PDF. During this OCR process, the text information in the scanned image is analysed by OCR software. An OCR converter compares this character information against a pre-trained character set and does the “character recognition”. After this, an invisible text layer is added on top of the PDF scanned image. This new format in the form of a “sandwich PDF” is called a “searchable PDF”. It is called a searchable PDF because the text in this scanned PDF can be searched or indexed just like any other text document.
