📊 Visual Comparison - Before vs After

Quality and Performance Comparison

Before Optimization

Before: Original image with large file size (2.4 MB), slow loading (8.2s)

After Optimization

After: Optimized image (380 KB), faster loading (1.1s), same quality

Performance Metrics

Performance improvement: 84% smaller file size, 86% faster loading

Performance Metrics

Before vs After Comparison

Visual comparison: See the difference optimization makes

| Metric | Before | After | Improvement | |--------|--------|-------|-------------| | File Size | 2.4 MB | 380 KB | 84% smaller | | Load Time | 8.2s | 1.1s | 86% faster | | Quality Score | 100% | 98% | 2% loss | | Core Web Vitals | 45 | 92 | +47 points | | Conversion Rate | 1.8% | 2.7% | +50% |

Key Insight: Proper optimization reduces file size by 70-85% while maintaining 95-100% visual quality.
