Unfortunately, most web browsers don't read this profile and most people don't have calibrated monitors, so the default color space, sRGB is generally assumed. Assuming you have a color-managed environment ( calibrated and profiled monitor), this profile is used to display the colors as they were intended to be shown. Color profiles are used to the viewer's display how the RGB values within the image data should map to real-world colors. The Save for Web method will remove these and still allow JPEG decoders to work.īoth Save for Web and Save As give you the option of including the ICC Color Profile within the image. In most output JPEG files, special markers are used to indicate additional information or provide resiliency in the case of errors / corruption. But, if you plan to share your images on a photo hosting site and would like to indicate the focal length, aperture and other parameters to your viewers, Save for Web will not be the right method. For simple images on a web site or for privacy reasons, you may want to hide the time/date a photo was taken, or other parameters. For many this is a useful feature, while others will completely avoid Save for Web because of it. Optimize to File Size: Ability to automatically select both the file format (JPEG or GIF) and JPEG compression level to achieve the selected file size.The main features in Save for Web include: To this end, two methods are used to achieve this: a) a live preview of changing JPEG compression quality sliders and b) the removal of all unnecessary metadata (JPEG markers) in the output file. Save For Web JPEG outputīecause the Save for Web command is intended to be used for images that are destined for display on the internet, one of the primary goals is in optimizing the file size as much as possible while still retaining acceptable image quality. The focus on this page will be on the JPEG output format.

PNG-8 - Reduced color depth (2-256 colors) and dithering options defines quality.No transparency.ĭifferent palette sizes (2-256) and dithering options define quality. More flexibility with each supported option. The ouput image file formats as the Save As dialog, but it does offer The Save For Web dialog box doesn't provide as much flexibility in Save for Web automatically converts the color depth for you. You can convert to 8 bit RGB by selecting Image -> Mode -> 8-bits/channel. 16-bit ModeĪs Save As does not support for 16-bit images, it may be necessary to convert to 8-bit first, save and then undo the color depth conversion step if you plan to continue working on the file. However, considering that it also includes the time and date of the original shot, it may have privacy implications. Most photo sharing sites (such as pbase) automatically extract this EXIF information, for the benefit of other photographers. One of the main reason that photographers choose Save As instead of Save for Web when sharing photos is so that the EXIF metadata (which includes camera information and shot details) can be displayed to other interested viewers. As shown below, this additional data may consume approximately 40KB. Resulting image at the cost of increased file size. Medium (such as the internet), additional information is encoded into the As this output method is not optimized towards transmission over a low data-rate The Save As dialog includes a very large number of output fileįormats, as it is the standard method by which users will generate
