Let’s briefly discuss the difference between raster and vector image formats and lossless versus lossy compression. Speaking of image formats, we should clarify these and a few other common terms before diving into the image types. For instance, the SVG format is a vector format and an excellent fit for icons, but it isn’t suitable for photographs because those are stored using a different image format known as raster. Some formats have properties that only make them useful for images of a particular type. Because of the differences in compression algorithms, some image formats result in smaller file sizes with the same image quality, but at the expense of features like image transparency. Different image formats also use different methods of compression, a process that encodes a file’s information to reduce its total size and make it faster to download on a webpage. The simplest explanation for the wide variety of image formats is that each one serves a different purpose.
Here’s a list of the image file types we’ll be covering in this article: You’ll learn how to maximize image quality while keeping file size low, thereby increasing the performance of your websites and applications. We focus specifically on the types of images that a web developer would use-there are many more file formats out there, but these are the most popular ones on the web.īy the end of this article, you’ll know when and how to use all of the image file formats we discuss and can be confident in choosing the right one. To simplify the situation, we’ve compiled a guide that covers each popular image format in detail. We know it can be challenging to keep up with all of the image file types in use today.
