Using PNG in email, Portable Network Graphics, offers a wide range of attractive features, including “a full range of color depths, support for sophisticated image transparency, better interlacing, and automatic corrections for display monitor gamma. This means that if you make a color transparent, that color will become transparent in the entire image.Īnother benefit of using GIFs is that they support animation, which is an increasingly popular technique in email design! Check out this great animated GIF from Jack Spade: PNG However, GIF transparency is not selective.

Check out the example of our logo as a transparent GIF set against a white background and a dark background: This allows you to put a GIF over a colored background, or even a photograph, and you won’t see a border around the image.

One of the major benefits of GIFs is that they preserve transparency, which means that you can use image-editing software to select colors in a GIF image’s color palette to become transparent. Not good for images w/ more than 256 colors GIF stands for Graphics Interchange Format and is “one of the file formats used to display indexed-color graphics and images in HTML documents on the web.” This means that a GIF will only display a maximum of 256 colors as a result, GIFs are great for images with simple illustrations and blocks of colors, like logos and icons, but probably not the best option for photographs. The very thing that helps make photographs look more realistic at high compression sticks out like a sore thumb when you save a text or clip art image as a JPEG file.” If large headlines look that bad, can you imagine how illegible smaller copy might get? GIF Here’s the same example zoomed in:Īs explains, “these little grey artifacts are part of the way JPEG compression works. Artifacts (the little bits of “fuzz” in the space around the letters) in the JPEG cause the text to look blurry or dirty. Here is a snippet of text saved as a JPEG:īy way of contrast, here the same text captured as a GIF (we’ll get to GIFs next):Īs you can see, the text is much clearer in the GIF. However, JPEGs are probably not the best option for images containing text. Here is a snippet of text saved as a JPEG:

As a result, if you choose the maximum quality option, your image will most likely be indistinguishable from your original photograph, albeit with a correspondingly larger file size.Īfter compression, JPEGs tend to create artifactsĪs stated in the chart above, JPEGs are great for photographs and images with lots of colors. In most design programs, you can choose the degree of compression you wish to apply to individual images-just be aware that by doing so, you also will alter the image’s quality. JPEGs are also “ lossy,” meaning they retain all color information, but compress file size by selectively discarding data-and that compression can result in a loss of quality.

JPEG images (short for Joint Photographic Experts Group) are “full-color images that dedicate at least 24 bits of memory to each pixel, resulting in images that can incorporate 16.8 million colors,” and are frequently referenced by their file extension, JPG.
