Image Optimization Best Practices

To get the best results from image optimization, follow these best practices:

• Choose the Right Format: Use JPG for photos, PNG for graphics with transparency, WebP/AVIF for modern browsers
• Balance Quality and Size: Find the sweet spot between file size and visual quality
• Resize Before Optimizing: Resize images to their display size before compression
• Use Responsive Images: Create multiple sizes for different screen resolutions
• Test Different Formats: Compare results across different formats to find the best option
• Maintain Aspect Ratio: Preserve image proportions when resizing
• Optimize for Web: Remove unnecessary metadata and color profiles
• Consider Retina Displays: Account for high-DPI screens when sizing images

File Size Reduction

Image optimization typically reduces file sizes by:

• 30-60%: For already optimized images with moderate compression
• 60-80%: For unoptimized images with aggressive compression
• 80-90%: When converting to modern formats like WebP or AVIF

For example, a 2MB JPG image might become 400KB after optimization, and only 200KB when converted to WebP format.
