Image optimisation is the process of compressing images and resizing them to reduce the file size without sacrificing too much image quality. In addition to compressing image size and maintaining quality, the image optimisation process also includes correct file names, file types, thumbnails and alt attributes. This process is designed to reduce page load times, optimise for search engines, provide a better user experience and reduce bandwidth usage.
Image size: The size of an image can significantly affect page load times. Large images take longer to load and can slow down your site.
Image formats: Images come in a variety of formats, each with their own advantages and disadvantages in terms of quality, compression and transparency. You should choose the best format for your image type and content.
Compression: Compressing images can reduce file size, which can help speed up page load times. However, excessive compression may result in a loss of image quality. It is recommended that lossless compression is used wherever possible.
Responsive design: Your website should be designed to be responsive, which means it should adapt to different screen sizes and resolutions. This includes the images used on the site, which should be optimised for different devices and screen sizes.
