Vector graphics instead use a system of lines and curves on a cartesian plane, scaled in comparison to the total area, not any single pixel. Unlike the static raster image file formats, where each design shape and color is tied to a pixel, these formats are more flexible. SVG, EPS, AI, and PDF are examples of vector image file types. The vast majority of the photographs or images you see on the internet use a raster image format. This ends up creating a blurry, pixelated, or otherwise distorted image. Since they’re static, you cannot efficiently resize the images, the original design and pixels will simply get stretched to fill the extra space. Raster image file types display static images where every pixel has a defined color, position, and proportion based on their resolution (for example 1280×720). The most common image formats for the web ( JPEG, GIF, and PNG) are all under the raster category. Let’s take a closer look at each category. The biggest drawback is that almost no one uses it.Image file types and formats are divided into two main different categories: raster image files and vector image files. It doesn’t support animation, but it’s not limited to 256 colors. PNG is very similar to GIF, but with improved compression. It compresses simple graphics or hand-drawn images very well. PNG does have transparency, but GIF is the only format for animated images.
GIFs can also be used for animated and transparent images. GIFs work best for drawings and graphics that use just a handful of colors, such as “line art.” JPEGs are typically used for scanned or digital photographs that need a large number of colors. It all depends on the kind of image you have. Keep an eye on this technology, but stick to JPGs and GIFs for now.

It’s promising however, it is not the standard, and many Web browsers don’t know how to read these files.

PNG stands for Portable Network Graphics, and it’s an open lossless compression format, designed to replace the older GIF format.

A larger file size means longer download times for your audience. Higher quality will lead to a larger file size. When you create a JPEG, you can usually select the level of quality you want. It takes advantage of our perceptive abilities by smoothing over areas of the image, creating larger blocks of solid color. JPEG compression is based on the idea that certain minute differences in images cannot be perceived by the human eye. JPG usually looks clear, as is evident in the example here. Unlike GIF, its compression scheme isn’t lossless, but lossy, so it does throw away some of the data. JPEG (or JPG) stands for Joint Photographic Experts Group, named after the standards committee that developed it. The fewer colors in your image, the smaller the palette can be, and the smaller the file size you’ll get. Unfortunately, dithering also makes the image file bigger, because blocks of colors must be saved in the palette. Dithering works well for images that have gradual changes in colors. Many image-editing programs allow you to “dither” the image, which is a way of determining which colors to keep for highest visual quality.
The houseplant photo shown here was saved as a GIF, and as a result, appears patchy. If you save an image as a GIF but it calls for more than that number, some will be lost. A color palette is a list of all the colors in an image. Another important concept in GIFs is the color palette. The GIF file uses special compact codes for large areas of a single color. Line art, such as the Catalyst logo shown here, is ideal for. It uses a “lossless” form of compression, which means that when you save the image, you don’t lose any of the data. GIF stands for Graphics Interchange Format, and it is a patented compression format owned by CompuServe and Unisys. Here are the basic differences you’ll need to consider. Your choice of format should depend on the kind of image you’re using. Web graphics typically come in three varieties. Putting those images up on your Web site can be a confusing process, however.
