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.

No. All conversion happens inside your browser.

Up to 30 files, 80 MB each on the free tier.

JPG has no transparency, so transparent areas are filled with your chosen background color.
