PNG compression is optimized for graphical images and images that use less than 16 colors. PNG is the best format for screenshots and most computers will save screenshots automatically as a PNG. PNG is not an option when it comes to print, as it doesn’t support a 4-color (CMYK) process. However, this will (in most cases) yield a very large file size. Boasting a “lossless” compression, you can save a PNG and not lose any quality. PNG is another very common and versatile image format found on the web today. The example below shows no noticeable visual contrast. When saving photographic images, JPG is definitely your best bet versus a lossless format, such as PNG. However, they do don’t support transparent backgrounds and cannot be easily layered with other elements. JPG’s save DPI (dots per inch) information and are still a common format for print usage. It’s always a good idea to keep a copy of your original photo is a “lossless” compression format. But don’t forget: every time the photograph is re-saved, the number of artifacts will increase. JPG compression is still optimized for photographs, making artifacts virtually invisible to the naked eye. Look at the difference in the following comparison, especially around the detailed edges of the flower petals. Known as “artifacts,” this loss in quality appears as small, blocky elements.
This loss is especially visible on text and small details. JPG’s are compressed using what is called “lossy” compression, which means there is always a loss of quality as you save. It’s highly compatible and boasts a small file size with very little noticeable quality loss. JPG is perhaps the most common image format used on the web.
