Image size is over 100 KB pages issue means that URLs contain images of size over 100 KB.
URLs contain images of size over 100 KB. The figure of 100 KB is relatively arbitrary – there is no hard and fast rule as to what constitutes an image that is ‘too large’.
Why it’s important
The main reason why it’s so important to optimize your images is that 90% of most websites are graphics-dependent and therefore there are a lot of image files. Leaving these images uncompressed and in the wrong format can drastically slow down your web page load times.
How to fix this issue
Here are the most common ways to optimize your images for the web.
Reduce the white space around images – some developers use whitespace for padding which is a big no-no. Crop your images to remove any whitespace around the image and use CSS to provide padding.
Use proper file formats. If you have icons, bullets, or any graphics that don’t have too many colours use a format such as GIF and save the file with lower amounts of colours. If you have more detailed graphics then use JPG file format to save your images and reduce the quality.
Save your images in the proper dimensions. If you are having to use HTML or CSS to resize your images, stop right there. Save the image in the desired size to reduce the file size.
