Why Screenshots Are Often Heavy
Modern screens are high resolution (retina).
A full-screen capture can exceed 5 MB.
PNG is often used by default (heavy for large images).
Interface gradients and transparency add weight.
Best Format for Screenshots
PNG: best for sharp text and interfaces.
JPG: acceptable if no critical fine text.
WebP: excellent compromise for modern web.
PNG-8: often sufficient and much lighter.
Smart Resizing
Retina screens generate images 2x larger than needed.
Reduce to actual display size.
600-800px wide is sufficient for most uses.
Text remains readable even when resized.
Crop the Essential
Capture only the useful area, not full screen.
Fewer pixels = lighter file.
Focus on important information.
