How Image Compression Works
Our tool employs advanced compression techniques to remove unnecessary data and optimize image encoding. It balances **lossy compression** for maximum size reduction and **lossless optimization** for quality‑sensitive images. :contentReference[oaicite:2]{index=2}
Why Image Compression Matters for SEO
Large images are often the heaviest part of a webpage and can slow down loading speed, increasing bounce rates. Compressed images load faster, improve Core Web Vitals (like Largest Contentful Paint), and help your site rank higher in search results. :contentReference[oaicite:3]{index=3}
