The Complete Guide to Image Compression
What Is Image Compression?
Image compression is the process of reducing the file size of an image while maintaining acceptable visual quality. Smaller images load faster on websites, consume less bandwidth, and improve user experience — leading to better SEO rankings, lower bounce rates, and higher conversions.
Lossy vs Lossless Compression
Lossy compression (JPEG, WebP) permanently removes some image data for dramatically smaller file sizes — the quality loss is often imperceptible at settings above 60%. Lossless compression (PNG) preserves perfect quality but achieves less size reduction. For web images, JPEG at 60-80% quality offers the best balance.
Why Image Compression Matters for SEO
Google uses page speed as a ranking factor. Large, unoptimized images are the #1 cause of slow-loading pages. Compressing images improves Core Web Vitals metrics (especially Largest Contentful Paint), directly impacting search rankings and user experience.
Choosing the Right Image Format
JPEG is ideal for photographs and complex images. PNG works best for screenshots, graphics with text, and images requiring transparency. WebP offers superior compression for both types — 25-35% better than JPEG at equivalent quality — and is supported by all modern browsers.
