![]() To improve the performance of your site, use one of the following techniques: For example, a GIF that is just a few seconds long can be a few megabytes in size. Improve the performance of sites that are using animated GIFs one of two ways:Īnimated GIFs, while extremely popular, can be huge files that require lengthy load times. Such file format conversions are pretty easy to do, and there are an abundance of software options you can choose from, including free web-based utilities such as the ones from Pic.io and Convertio. However, modern compression techniques are much more performant than LZW, and you can take advantage of this by using formats that utilize these techniques, such as PNGs. GIFs were originally created to use a lossless compression technique called the Lempel-Ziv-Welch (LZW) algorithm, which was defined in the 1970s. While the two formats are very similar in terms of being good choices for displaying simple graphics, PNG files have the advantage of being able to compress to a size 5–25% smaller than the equivalent GIF file. The easiest way to improve the performance of your site is to render your image using the PNG format instead of the GIF format. Improve the performance of sites that are using static GIFs by converting to PNG. Later on in this post, we'll cover the impact of both types of optimization on GIFs. While your file size remains larger than if you had used lossy compression, your image’s quality does not degrade over time. Lossless compression: Lossless compression preserves all of the data from the original file, which means that the compressed file can be uncompressed to gain the original file.However, every time you save the file after compression, the quality of the graphic degrades somewhat, which can result in a fuzzy, pixelated image over time. Lossy compression: Lossy compression removes some of the data from the original file, resulting in an image with a reduced file size.There are two methods of compression that are commonly used: One of the primary methods for optimizing GIFs is to compress them. There are two methods for compressing images: ![]() We'll first dig into ways to handle static GIFs, and we'll end by discussing ways to minimize the overhead resulting from animated GIFs. In this section, we'll cover several ways you can improve the performance of your site with regards to using GIFs. How to improve the performance of your site while using GIFs As such, usage of GIFs leads to heavy page weights and poor user experiences resulting from slow page load speeds. While they are excellent for capturing your user’s attention and are universally liked for providing short bursts of information in an entertaining way, GIFs were not designed for animation (despite them being commonly used for such). Performance matters when it comes to designing your web pages, and GIFs are not the most performant of image options. This article will cover ways to optimize your GIFs, both static and animated, and will offer an excellent alternative you can use to eliminate the page bloat resulting from use of GIFs as animation. If you are using GIFs on your sites, it’s important that you take care to optimize your GIFs so that they do not create too much overhead. In spite of their popularity and ubiquitousness on the Internet ( especially with regards to animated GIFs), GIFs are not the most performant of image options. This frame animation feature of GIFs ensures that the format remains popular, despite the rise of JPEG and PNG images. And to this day, little has changed regarding GIFs.ĭue to its simplicity, the widespread support for this format, and the ease with which it can be used to stream video clips, the GIF format is the oldest file format still commonly used today. ![]() Furthermore, web developers and designers could create animations via timed delays. ![]() Debuted by Steve Wilhite of Compuserve, GIFs improved on the black-and-white images in use during that time by allowing the use of 256 colors while maintaining a compressed format that could still be loaded by those utilizing slow modems. The GIF ( Graphics Interchange Format) format was originally developed in 1987. ![]()
