Optimising Images for The Web
Visual content is really important on any website, not only does it add to a website’s aesthetics, but it also provides endless opportunities for SEO.
If a potential customer is visiting your webpage, they do not want to wait long for pages to load. If pages do take a long time to load, this could be due to many reasons, for example: large file sizes, a poor website server, large image dimensions or poor file formats.
If pages load slowly, regardless of number of images, there is a good chance that you have a poor website server. If you are planning to use images on your website, it may be worth investing in a better hosting solution. Or if the problem is intermittent, contact your hosting provider.
You can make your image files smaller by compressing them, however this is not a good idea if you receive large amounts of traffic. It may put extensive strain on the website server, or actually slow down page loading times for the visitor.
The best option is to ‘optimise’ your images. This includes rescaling, changing formats, and quality. This can be done with expensive photo editing software, or free online utilities such as webresizer.com. Not only can you optimise your images, you can also tweak other options such as sharpness and tint to bring out the best in your images.
After you have optimised your image, it is always a good idea to keep a backup of the original, so keep that in mind!
