Definition
Image optimization reduces image weight without unnecessary loss of visual quality.
What does it mean in practice?
For websites and online services, Image optimization affects response time, reliability, resource usage and the quality of the network path.
A practical Hostilla.pl example
Measure the same URL from a repeatable location before and after a change. Image optimization should be correlated with server response time, application logs, resource use, caching and the network path rather than judged from one browser refresh.
What should you check?
- the exact URL, device, location and test time
- a baseline for response time and page metrics
- PHP, database, disk, cache and resource usage
- one controlled change followed by the same test
