Best Practices for Image Resizing

• Maintain Aspect Ratio: Keep this option enabled to prevent distortion
• Start with High Quality: Always resize from a high-resolution source image
• Don't Upscale: Avoid making images larger than their original size
• Consider File Size: Compress images after resizing for web use
• Test Multiple Sizes: Create multiple versions for different devices

When to Maintain Aspect Ratio

The aspect ratio is the relationship between width and height. Maintaining aspect ratio prevents your images from looking stretched or squashed. Disable this option only when you need exact dimensions and don't mind potential distortion, or when you're intentionally creating a specific effect.
