Resize vs Crop

Action	What It Does
Resize	Changes overall dimensions (proportional)

Rule: Resize first, then crop if needed.

Tips for Quality Resizing

• Downscale only — making images larger always reduces quality
• Use WebP — better compression than JPG at same quality
• Retina-ready — save at 2x display size (e.g., 2400px for 1200px display)
• Don't resize multiple times — each resize degrades quality

When to Resize

• Before uploading to website (faster load times)
• Before sharing on social media (platform-appropriate size)
• Before emailing (stay under attachment limits)
• Before printing (correct DPI: 300 for print, 72 for web)
