Image size optimization is essential for optimizing your landing page.
When images are too large, they can take longer to load and affect the overall performance of your page. If images are optimized, the loading time will decrease, and visitors can view important information more quickly.
Below, you will find twelve useful tips that ought to help those who are struggling with their landing pages due to poor image optimization.
Use tools like ImageOptim or TinyPNG to compress the images without sacrificing quality. These tools will reduce image size without any noticeable changes in image quality, thereby reducing loading times.
JPEGs tend to load faster than PNGs, so if you don't need transparency or alpha channels, you should be using JPEGs instead.
While high-resolution photos look great on high-end devices, they can slow down a web page significantly on less powerful ones.
Consider reducing the resolution of larger photos so that they still look good but don't take as long to load.
CSS sprites combine multiple images into one larger file that can be loaded at once instead of numerous separate files, which helps with loading speeds and bandwidth usage.
Make sure you're cropping images at the right dimensions for their intended use — no bigger than necessary—to save space and reduce loading time.
If you have a lot of images on your page, consider automating image compression with plugins, such as WP Smush or ShortPixel for WordPress websites or services like Kraken or Cloudinary for other web development platforms or applications.
Lazy loading only loads an image when it is needed, rather than preloading everything up front.
It may sound counterintuitive, but lazy loading reduces initial load times because it doesn't load every image until it is scrolled into view.
Hotlinking is when someone uses an image hosted on another server instead of hosting it on their own website.
This type of linking not only increases server traffic but also affects the performance of other people's websites - both negatively impacting the user experience.
Avoid hotlinking whenever possible and host your own images to keep webpage performance optimal.
Caching allows browsers to store static elements, such as images, in local storage so that they don't have to be downloaded each instance a person lands on a website.
This saves time during subsequent visits by allowing content such as images that haven't changed since being stored locally, resulting in faster page loads.
Every time someone ends up on a landing page, their browser must send a request for each element included in that webpage - including each individual image file used on that particular page ( even if those files are cached ).
Reducing HTTP requests helps reduce overall latency and improve performance speed by decreasing the amount of back-and-forth communication between client and server required for each request/response cycle ( i.e., decrease round-trip time ) needed in order to fulfill these requests successfully before displaying content all viewers can see together as expected.
CDNs store copies of static content like media files across various geographical locations - meaning users accessing content from different locations will get faster performance due to lower latency rates granted by better proximity between them & where resources are stored within respective networks mentioned earlier.
The method also decreases stress placed upon primary servers hosting websites with heavy amounts of traffic since CDNs take some pressure off those systems & distribute responsibility accordingly - keeping uptime & availability strong & consistent across the board throughout different regions worldwide.
