About the blog

Practical tutorials and references on image optimization, web performance, and e-commerce.

We write about what we measure running RoundCut in production: compression (WebP, AVIF), Core Web Vitals (LCP, CLS, INP), image formats for catalogs, and the small details that affect conversion.

Author

Editorial process and AI use

Articles on this blog are produced with AI assistance under a fixed editorial process: primary-source research done per article (sources are saved and verifiable), house style rules, and automated quality checks that block publication when any criterion fails. Every number, date and name cited traces to a source consulted on the article’s date. When a source doesn’t confirm a claim, the claim is left out.

Workflows and settings we describe are tested in RoundCut’s own tools before becoming recommendations. Found a mistake? Contact us and we’ll correct it and note the update on the page itself.
