Why Image Compression Matters More Than Ever
Images account for more than 60% of total web page weight. Optimizing your images isn't just a technical nicety—it directly affects your Google Core Web Vitals, bounce rates, and organic SEO ranking.
Lossless vs Lossy Compression: What is the Difference?
Lossless compression reduces file size by eliminating redundant metadata and reorganizing color indexing without discarding any pixel information. Formats like PNG and lossless WebP excel in this category.
Lossy compression selectively discards imperceptible high-frequency visual details to achieve dramatic file size savings (often 70% to 90%). JPEG and standard WebP are prime examples.
Best Practices for Web Masters
- Always compress before uploading to WordPress, Shopify, or static web servers.
- Use next-gen formats like WebP whenever possible.
- Set explicit width and height attributes in HTML to avoid Cumulative Layout Shift (CLS).
