What are the considerations for image optimization on your website?
Optimizing your website for improved performance online takes a number of different actions and approaches and involves looking at all aspects of your website, including the imagery. The images you use, and the way that these are stored and loaded, are crucial for helping to improve your SEO efforts. As a result, you will need to consider a range of factors, including:
- Choosing the right format
- Choosing the right compression method
- Responsive imagery
- Browser caching
The image format and compression are two of the most important factors for website optimization, but these are also the two factors that companies often struggle with the most.
Choosing the right format for images and visual content on your website
The format of the images you display on your website can make a big difference to the optimization process. This is because each different format is specifically deigned for a different purpose. These formats include:
- JPEG: Best for still images, real-world images, and complex coloring;
- PNG: Best for web images like logos and flat images;
- GIF: Best for low-resolution images, animated graphics, small icons, and simple images — however, it is not advisable to go with GIF format but rather use mp4 or a webp instead;
- TIFF: Best for high-quality and large-size print graphics;
- WebP: A modern image format that offers superior compression while maintaining great quality.
By selecting the right format for your visual content you can reduce bandwidth consumption. This allows your website to load faster and provide a more effective user experience.
One new format to be aware of is AVIF. This has been designed specifically fore website performance and can even surpass WebP in quality. AVID provides the same positive qualities as the above image formats, and also offers an excellent compression ratio. In fact, AVIF provides almost 50% savings in size when compared to JPEG format. This is something all companies should be considering for the future.
Choosing the right compression method for images and visual content on your website
Reducing the size of the image through compression is essential, once you have selected the right format. This will allow the image to load more quickly, and take less space. These are the two methods for compressing images:
- Lossless compression: This allows all the unnecessary metadata linked with the images to be removed without degrading the quality of the image.
- Lossy compression: This method reduces the quality of the image slightly, but this is not perceivable by the human eye, and so your website can still look amazing, while enjoying a faster loading speed.
