FAQ

Frequently asked questions

3 answers

Will image compression reduce quality?

It can. Lower quality settings usually produce smaller files but may add visible compression artifacts.

Can I compress PNG images?

Yes, if the browser can decode the PNG. The output format and transparency handling depend on the tool implementation.

Why is the compressed image not much smaller?

Some images are already optimized, and file size depends on content, dimensions, and chosen quality.
