Lossless JP2s are good for archiving and master copy purposes, their size tends to be noticeably smaller than truecolor PNGs. Has both lossy (for better filesize) and lossless (for perfect quality) settings. There is also MNG (a variation on PNG), but there are few programs that can read MNGs, and only a paltry handful that can create them.Ī good choice for photographic images. Note about animation: There is also the flash/SWF format for animation, but most progs that can create SWF files are commercial. Excellent compatibility, excellent speed, good compression (although indexed PNGs are much smaller on any image over 40x40px). Best choice for tiny images (approx 40x40px images or less), best format for animated images due to compatibility reasons. One weakness of JPG is that it handles red very poorly. Excellent compatibility, excellent compression for truecolor and greyscale images, excellent speed. Is best for putting photographic images on the web, as it results in a file approx 1/10th the size of lossless formats, but with little/no visible quality loss. Should -not- be used for archiving or master copy purposes since it is a lossy format (some image data is thrown away every time you save the image).

Should be used with photographic-type images, using with images that contain areas of solid color and sharp edges will result in "echos" and artifacts, plus a bloated filesize. In short, stick to single color transparency or no transparency, and you'll be fine. MSIE can handle single color transparency with no problems, but can't handle alpha transparency.
PNGs have 2 different types of transparency alpha transparency (allows for partial transparency and shadow effects), and single color (GIF-like) transparency. The only time most people need to think about alpha or gamma chunks is when dealing with transparency. In addition, MSIE -can- handle PNGs (both true color and indexed) just fine, the only problem is with alpha and gamma chunks.

These only arise with internet explorer, all decent browsers have full support for PNGs. Note: There is a lot of confusion about whether PNGs are a good format to use on the web due to compatibility questions.
Excellent compatibility, excellent filesize, great speed. Indexed PNG (aka 256 color PNG, aka paletted PNG):īest format for graphical images (images with sharp edges and large areas of solid color), and screenshots. Has excellent compression for a lossless format (only exceeded by JPEG2000), excellent compatibility, good speed. Great for archiving, master copies, or any other situation where perfect quality is more important than filesize.
Should not be used on the web due to large file sizes. PNG comes in 2 flavors, truecolor and indexed. This is to answer some questions about the strengths, weaknesses, and usage of some of the more common image formats.
