How Image Compression Works
Image compression reduces file size by removing data that the human eye can't easily detect. There are two main types:
Lossy Compression
Removes some image data permanently to achieve dramatic file size reductions. JPEG and WebP use lossy compression. At quality 80%, file sizes shrink 50-80% with barely noticeable quality loss.
Lossless Compression
Reduces file size without any quality loss by optimizing how data is stored. PNG uses lossless compression. Savings are typically 10-30%.
Why Compress Images?
Faster Website Speed
Images account for 50-75% of most webpage weight. Compressing them is the single most effective way to speed up your site.
Better Core Web Vitals
Smaller images improve Largest Contentful Paint (LCP) — a key Google ranking factor since 2021.
Lower Bandwidth Costs
Compressed images use less CDN bandwidth, reducing hosting costs — especially at scale.
Better User Experience
Pages that load faster have lower bounce rates. Users abandon pages that take longer than 3 seconds.
