Understanding Resize Modes
- Exact: Resize to specific pixel dimensions. Use aspect ratio lock to prevent distortion.
- Percentage: Scale proportionally by a percentage (10% to 200%). Great for quick resizing.
- Fit: Resize to fit within maximum bounds while maintaining aspect ratio. Perfect for thumbnails.
Best Practices for Image Resizing
- Always resize down: Upscaling causes quality loss and pixelation
- Lock aspect ratio: Prevent distortion by maintaining original proportions
- Use retina sizes: For high-DPI displays, create images at 2× the display size
- Batch process: Resize multiple images at once to save time
