The ability to convert images to text is technically referred to as Optical Character Recognition (OCR). It can be really useful whenever you need to convert a paper document into an editable, digital form.
There aren’t many OCR apps on android. Of the few that are available, Google Goggles is the most popular one. It’s entirely free and does exactly what it promises – copy text from a picture and paste it elsewhere.
