![]() Think of it as a way to fit more data in the same amount area. Image compression utilizes specialized mathematical techniques to reduce the file size, while maintaining its resolution (remember, number of pixels!) and visual dimensions. By truly resizing the resolution of your images (not just visually!), a browser can load the image muchfaster, minimizing wasted time loading an unnecessarily large image. Ultimately, resizing your image is critically important for load time of your page. It’s important to learn how your CMS is handling images as it can have a drastic impact on your user’s experience, page speed, and even Search Engine Optimization (SEO). Some Content Management Systems (CMS) will have tools built in that truly do essentially take the original image uploaded and create multiple smaller versions of the image with smaller dimensions that can be used in the various sections of your website based upon what display size is needed. Using the same math, we are now only loading 129,600 pixels In other words, the 1920 width by 1080 height image truly becomes a 480 width by 270 height image and then is displayed as a 480 by 270 image. On the other hand, there is a way to resize the image properly by lowering the resolution and thus exporting fewer “pixels” of data. Resizing an Image by Exporting a Truly Smaller Version When an image is resized with this method, the same amount of data will remain, but the image will be displayed smaller from a visual perspective. Note that resizing an image simply by defining HTML attributes or scaling with CSS does not decrease the file size. ![]() Unfortunately, in this case, the user’s browser still was forced to download the high-resolution image (1920 by 1080) which negatively impacts page speed and the user’s experience. What happens is the full image of 1920 by 1080 loads (2,073,600 pixels) in the background and is resized visually either via CSS or HTML attributes to the desired display size. However, here’s the kicker your website is still likely loading the full image even if you don’t realize it. Many website tools may allow you to upload a large image and then automatically or drag-and-drop resize it visually to your intended placement on the webpage. For instance, you may take a 1920 pixels width by 1080 height image and resize it down to 480 pixels width by 270 height. Resizing an image is certainly important to ensure it fits within the constraint of its placement on your webpage. ![]() Resizing an image is typically thought of as simply changing the visual dimensions of the image. The total pixels are 2,073,600 pixels – that’s a lot of pixels! For instance, you might commonly hear a 1920 width x 1080 height image mentioned. How many pixels are in an image is calculated by multiplying the width (measured in pixels) by the height (also measured in pixels). Images consist of pixels which are points of data that make up the image. Resizing Images Resizing and Image with HTML Attributes or CSS – Not Recommended Two important image techniques exist to create fast, visually appealing websites. Conversely, if your small business website only contains tiny, low-resolution images, it might load quickly, but is not nearly as visually appealing and can give the impression that your brand is low-quality. ![]() Although website visitors may want to see all those images, they often do not wish to wait long for the images and the remainder of your webpage to load. Big, small, and some with stunningly high definition. ![]()
