Resizing Techniques
🔒 Constrained Resize
Automatically maintains aspect ratio by scaling proportionally.
How it works:
- • Set either width OR height
- • Other dimension adjusts automatically
- • No distortion guaranteed
- • Most common and recommended method
Example: Resize to 800px width
1200×800→800×533
✂️ Crop to Fit
Crops image to match exact dimensions while preserving aspect ratio.
How it works:
- • Set exact width AND height
- • Crops excess to fit dimensions
- • No distortion, but content may be lost
- • Good for thumbnails and fixed layouts
Example: Crop to 400×400px
1200×800→400×400
Working with Different Ratios
🎯 Converting Between Ratios
16:9 → 4:3
Crop sides
4:3 → 16:9
Crop top/bottom
16:9 → 1:1
Crop to square
