Steps to verify
- Read actual source and output sizes.
- Compare formats and dimensions.
- Choose a suitable smaller result.
How to interpret the result
Format, source optimization and browser encoding affect output. Do not label a larger result as a saving.
Deciding what to do next
Retain the original if alternatives do not improve it. Review appropriate resizing separately and preserve the source.
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 larger output mean processing failed?
It can be a valid re-encoding result. Compare files to determine savings.
