How much does this help SEO?

Image optimization is one of the single biggest levers for LCP — the dominant Core Web Vitals metric for most blog posts.

Which format should I use?

WebP is the modern default. Use JPG at ~80% for maximum compatibility. PNG only when you need transparency.

Will the aspect ratio be preserved?

Yes in "fit" mode. "exact" stretches to the exact size without cropping.

Does upscaling blur the image?

Upscaling reduces clarity. Stay at or below the original size when possible.
