Understanding Image File Formats

Different image file formats serve different purposes, and understanding which to use can greatly impact your website’s performance. JPEGs are ideal for complex images with lots of colours, while PNGs offer better quality for simpler images. SVG is perfect for vector-based images.

Reducing Image Size

Large, high-resolution images can significantly slow down your page load speed. By reducing the size of your images, you can improve this speed without compromising too much on image quality. Tools like Photoshop or free online platforms can help you compress your images and maintain a balance between size and quality.


Utilising Lazy Loading

Lazy loading is a technique where images only load when they come into the viewer’s screen. This means that the browser doesn’t have to load all images simultaneously when a user lands on your page, leading to faster load times. This is especially beneficial for pages with a large number of images.


Leveraging Browser Caching

Browser caching allows browsers to store copies of your website’s images. This means that when a visitor returns to your site, the browser doesn’t need to reload the entire page, leading to faster load times.


Implementing Responsive Images

With the diversity of devices used to browse the web, your images need to be responsive. This means they should adjust to fit the size and resolution of any screen. You can achieve this by setting a max-width for your images in your CSS and using HTML’s srcset attribute to specify different images for different screen resolutions.

SEO Optimisation for Images

Images can also contribute to your SEO efforts. By providing descriptive file names and alt text, you can help search engines understand the content of your images and improve your visibility in image search results.
