Disclosed are methods, apparatuses, systems, and/or non-transitory computer readable media for improving/optimizing image compression quality settings. A method of compressing an input image, using at least one processor, includes verifying a desired compression quality value desired for compressing the input image, determining an optimal image quality value that corresponds to a target peak signal-to-noise ratio (PSNR) from a set image quality range based on the desired compression quality value, and outputting an image file encoded at the optimal image quality value as a compressed file of the input image.
