In this article I’ll try to explain how to adjust that JPG or JPEG extensions), which can achieve compression ratios of 10:1 with almost noĭepending of the program that you use for saving JPEG images, there are available some optionsįor adjusting the compression of the image. #History of image compression standards how to# Options and optimize the ratio between image quality and file size. Into account that some images are more suitable than others for JPEG compression (see flat images compression below). The two basic options that are almost always present in every “Save JPEG” dialog are theĬompression/quality of the image, and the standard/optimized/progressive formats.īoth compression and quality refers to the same parameter but one is the inverse of the other (e.g. Percentage-based scale 35% compression is equal to 65% quality). Parameter depends of the image quality or file size you need/want to obtain, getting the best ratios with 50%-85% Depending of your program of choice you’ll findĮither, but the result is the same: the more compression, the lesser image quality. The standard (baseline) and optimized (baseline optimized) settings provides the Of image quality (equivalent to 50%-15% compression). Same image quality but the optimized format provides a 2%-8% reduction of the imageįile size, so there is no reason for not use always this setting when not using the progressiveįormat. Of displaying the image while it is downloaded, at the cost of a slight increase in the file The progressive format also provides the same quality, but offers an alternate method

Quality level selected: it applies subsampling for Medium and Low Adobe Photoshop also contemplates this option but it’s adjusted automatically depending on the The subsampling ratios according to the spec are 4:4:4 (no subsampling),Ĥ:2:2 (standard subsampling) and 4:1:1 (worst quality, rarely used). Quality and file size, there are some situations in which using no subsampling (4:4:4) provides a noticeable increase While the standard subsampling is usually adequate for most images, providing an good ratio between image Levels and uses no subsampling for Maximum and High This information usually takes a lot of space, so make sure that saving this data is disabled in This data include information about the camera configuration and conditions at the time The most notableĬases are when the image contains some portions with fine details, like text over an uniform background, and images thatįirst we’ll see an example of compression of images with fine detail:Īlmost all digital cameras store by default EXIF data in the In the image quality, even if you use a higher compression ratio in order to maintain the file size.
