💡 Image Compression Tips
Quality 70–80% is Sweet Spot
For web images, 70–80% quality gives 60–80% size reduction with virtually no visible quality loss.
Use WebP for Websites
WebP format is 25–35% smaller than JPEG at the same quality. All modern browsers support it.
PNG for Screenshots
Use PNG for screenshots, logos, and graphics with text. Use JPEG for photos and natural images.
Smaller Images = Faster Site
Google uses page speed as a ranking factor. Compressed images can dramatically improve Core Web Vitals.
