What is Image Optimisation?

Reducing image file sizes and choosing the right format to make web pages load faster.

Why It Matters

Images are often the largest files on a page, so optimising them can significantly improve load times.

Real-World Example

Converting a 2MB PNG hero image to a 200KB WebP format with no visible quality loss.

“Understanding terms like Image Optimisation matters because it helps you have better conversations with developers and make smarter decisions about your software. You do not need to be technical. You just need to know enough to ask the right questions.”
