A method for compressing a digitized image of a document using optical character recognition (OCR). The method includes performing optical character recognition (OCR) on the digitized image, identifying, based, at least in part, on a result of the performing step, a plurality of classes of characters comprised in the image, each the class of characters having an associated character value and comprising at least one character, pruning each class of characters, thereby producing information describing the plurality of classes of characters and a residual image, and utilizing the information describing the plurality of classes of characters and the residual image as a compressed digitized image in further processing.Related methods and apparatus are also disclosed.
