Why Image Compression Matters

Images typically account for 50-80% of a webpage's total size. Unoptimized images are the #1 cause of slow-loading websites, which directly hurts your Google rankings and user experience.

Google's Core Web Vitals specifically measures page loading performance. Compressing your images is the easiest and most impactful way to improve your site speed scores.

Lossy vs Lossless Compression

Lossless compression reduces file size without any quality loss — the decompressed image is pixel-identical to the original. PNG images use lossless compression natively.

Lossy compression removes some image data that humans can't easily perceive, achieving much higher compression ratios (70-90% size reduction) with virtually no visible difference. JPG and WebP support lossy compression.

Best Compression Settings for Different Uses

For web images: Use JPG quality 75-85% or WebP quality 80%. This gives 70-80% file size reduction with no perceptible quality loss on screens.

For e-commerce product images: Use JPG quality 85-90% to preserve fine details. For print-quality images or professional photography: stay at 90-95% or use lossless PNG.
