Website speed image tips
Use these before you upload or share the page.
A 100KB reduction per image on a page with 10 images saves 1MB of total page weight — that is often the difference between a 3-second and a 1.5-second load time on mobile.
JPEG at 70-80% quality is the best balance for photographs — file size drops 50-70% with barely visible quality loss. Use Skwish's quality slider to find the sweet spot.
For PNG screenshots and UI elements, try converting to WebP first — you will often get 60-80% smaller files with identical visual quality.
