FAQ
Questions about website image optimizer
What makes an image good for a website?
A website image should usually be large enough for the layout, compressed enough to load quickly and exported in a suitable format.
Is WebP always the best choice?
WebP is often a strong choice for modern websites, but PNG may be needed for some transparent graphics and JPG may be preferred for certain compatibility workflows.
Can this improve SEO?
Optimized images may help page experience and clarity, but this tool does not guarantee rankings. It provides practical SEO-oriented checks.
Does the optimizer create responsive image markup?
No. It helps prepare the image asset. Your website should still use responsive markup and caching where appropriate.
