Advanced Optimization Techniques
Compression Strategies by Content Type
Photography & Realistic Images
Use JPEG for photos with many colors and gradients. Higher quality for hero images, moderate for supporting content.
Graphics, Logos & Text
PNG preserves sharp edges and text clarity. Use for logos, infographics, and images with transparency.
Simple Graphics & Icons
WebP offers superior compression for modern browsers. 25-35% smaller than equivalent JPEG/PNG.
Animated Content
Use MP4 for better compression than GIF. Keep animations under 15MB for social media.
Mobile-First Optimization
With 80%+ of social media consumption happening on mobile devices, mobile optimization is crucial:
Visual Considerations
- • Use larger fonts (minimum 14px)
- • Ensure high contrast for readability
- • Place key elements in the center
- • Avoid fine details that disappear on small screens
- • Test on actual mobile devices
Technical Optimization
- • Target file sizes under 1MB for fast loading
