Compress to 500 KB

This lesson is part of Web Developer Tools · All levels

Summary

The 500 KB target is loose and provides space for large-scale high-quality web photos. The final size is heavily influenced by pixel dimensions and the complexity of detail: photographs of leaves or sand are harder to compress than plain backgrounds. Modern formats such as WebP or AVIF can produce equivalent quality on smaller sizes. Use 500 KB only if the image is large, not for thumbnails.

Key points

500 KB is good for big, high-quality photos.
The more complicated the details, the more data we need.
WebP or AVIF can give you better quality at the same size.
Do not use a 500 KB file for small-scale images
Consider lazy loading so that a large image does not slow down the start of the page
