Are these image optimization guides free?

Yes. Every guide is free to read, has no paywall, and requires no account. The ImageForge compression tool they accompany is also free and private.

How often are these guides updated?

Guides are reviewed and updated as image formats, browser support and Core Web Vitals metrics change. The 2026 editions cover AVIF, WebP, the current INP metric and modern delivery patterns.

Can I compress images using what I learn here?

Yes — the ImageForge tool is linked from every guide. It runs entirely in your browser, so nothing is uploaded, and it applies the exact techniques described in these guides.
