How to interpret the result
Savings use the difference from the source and can be negative for larger output. Report actual file sizes.
Deciding what to do next
Record the selection reason and inspection time. Measure image changes and whole-page loading separately.
Feature scope
Export a new file at the same dimensions in the browser. Compare JPEG/WebP quality and format; PNG quality behaves differently and the output is not always smaller.
Frequently asked questions
Does a smaller image prove a faster page?
It can contribute, but inspect actual page assets and loading too.
