How to optimize website images for fast load speeds

Key quotes:

• "Having a website full of beautiful images is great and all but can be a huge bottleneck for page loading."
• "That would take ages to load and results in users leaving your website."
• "However, the background image takes 27.32 seconds to load where the user sees parts of the images loading in."
• "But now we have a low-resolution blurred image as our background."
• "This is perfect for the first seconds the page is loading but we want to give the user the great experience of our original background image."
• "To do so we want to first load in the low-resolution image and already load the high-resolution image asynchronous in the background."

Key quotes:

• "Have you ever wondered how sites that have beautiful, full width, hi-resolution images still load quickly? There are various tools online that will automate the process of creating progressive images; however, we don’t recommend them because all too often the site will embed metadata that increases the image size."
• "The file size of the image is based on the number of pixels within, or the resolution."
• "Additionally, when a raster graphic is loaded on a website, the server requests that the image be served."
• "SVG objects are scalable to any size because they do not use pixels like raster graphics."
• "As if that’s not enough, an SVG object has a smaller file size than a raster graphic that has a similar design."
• "Meaning a technical object, such as text, will be result in a larger file size than something simple like a circle."

Key quotes:

• "A simple way to do accomplish format and quality optimization is to use ImageKit to deliver your images."
• "The browser then decides the best image size to load on a particular device from the available list based on the device dimensions and the layout you specify."
• "A modern specification called Client Hints, makes it simple to get started with responsive images and makes the code look much cleaner as compared to the `srcset` and `sizes` attribute method."
• "ImageKit provides you with a URL-based DPR parameters along with resize and crop parameters, and also supports client hints, that makes it very easy to use responsive images and deliver perfect images across devices."
• "Even after you have optimized all of your images, loading too many of them is bound to slow down your website and negatively impact the user experience."
• "Just type in a page URL and within a few seconds it would give you suggestions regarding resizing, best format, lazy loading and HTTP/2."

• "In this article, we will give you recommendations about how to improve your website performance and page load time."
• "Website usability like website page speed, load time, and website responsiveness to user requests directly impacts customer loyalty."
• "Before starting your website speed optimization you should determine your current loading time and define what slows your site down."
• "The ways of website speed optimization listed in this article are very different and sometimes the solution to one problem can have the negative impact on another aspect of your site."
• "There are several performance evaluation tools that are worth trying: Once you have tested the speed of your website, you can start optimizing it."
• "First, run the performance tests on your page to find out which plugins are slowing down your website."

Key quotes:

• "Get full instructions and sign up here: https://support.cloudflare.com/hc/en-us/categories/200275218-Getting-Started Image compression is a great way to reduce the size of image files and increase page load speed."
• "If your library isn’t optimized and free is more important to you than the one-time $10–20 you’d spend to save hours of tedious clicking, use WP Smush."
• "For myself as well as 9/10 of the sites I optimize, that’s plenty for maintenance once I’ve optimized existing Media Library images."
