May 15, 2024•7 min read•Optimization
Image compression is essential for web performance. Here's how to do it right:
Why Compress Images?
- ✓ Faster Loading: Smaller files load quicker, improving user experience
- ✓ Better SEO: Google prioritizes fast-loading websites
- ✓ Lower Bandwidth: Saves hosting and data transfer costs
- ✓ Mobile Friendly: Crucial for users on slower connections
Compression Techniques
1. Use the Right Format
Choose formats based on your needs:
- • WebP: 25-35% smaller than JPG
- • JPG: Good for photos
- • PNG: For graphics and transparency
2. Adjust Quality Settings
Most formats let you adjust quality/compression:
- • Photos: 60-80% quality is usually imperceptible
- • Graphics: 80-95% quality recommended
- • Always test the visual result
3. Resize Before Compression
Don't serve oversized images:
- • Only use as large as needed for your layout
- • Create different sizes for responsive design
- • Use "srcset" for different screen sizes
4. Remove Metadata
Image metadata (EXIF data) can add 20-50KB:
- • Remove GPS, camera info, and comments
- • Keep only essential metadata
