This invention has as its object to avoid occurrence of image deterioration caused by image compression by selecting an appropriate compression parameter upon compressing a composite image generated by compositing a plurality of image data. To this end, an image processing apparatus according to this embodiment has the following arrangement. That is, the apparatus has an image composition step (step S 801 ) of generating a composite image by compositing a form image and original image, a checking step (steps S 802 to S 805 ) of checking for each image if each of the form image and original image to be composited is a scanned image which is generated by scanning an image by a scanner, or a PDL image which is generated via an application and is described in a page description language, a determination step (steps S 806 to S 809 ) of determining a compression parameter used to compress the composite image on the basis of a combination of the form image and original image to be composited checked in the checking step, and an image compression step (step S 810 ) of compressing the composite image using the compression parameter determined in the determination step.
