When it comes to saving photos for online use or for printing, JPEGs are the most common file format. But what is a JPEG, and how do you save a high quality JPEG in Photoshop? JPEG is an acronym for Joint Photographic Experts Group, and is a compression format used mainly for photographs. A high quality JPEG will have more compression than a standard JPEG, and will look sharper when printed. To create a high quality JPEG in Photoshop, you first need to define the compression level.
The higher the compression level, the smaller the file size, but the image will look less sharp. To create a high quality JPEG, use the JPEG quality setting of 50 or 60.
