JPG vs PNG vs WebP: Which Format Should You Use?
Choosing the wrong image format can bloat your website by 300%+. This definitive guide shows you exactly when to use JPG, PNG, or WebP for optimal performance.
Quick Decision Guide
🎯 Use This Flowchart
Photographs & Complex Images
→ Use WebP (or JPG as fallback)
Logos, Icons & Graphics
→ Use PNG (or SVG for vectors)
Images with Transparency
→ Use PNG or WebP (both support alpha)
Maximum Browser Compatibility
→ Use JPG + PNG with WebP fallback
TL;DR for 2025: Use WebP for everything when possible, with JPG/PNG fallbacks for older browsers. WebP offers the best of both worlds: JPG-like compression for photos and PNG-like features for graphics.

Side-by-Side Comparison
| Feature | JPG | PNG | WebP |
|---|---|---|---|
| Best For | Photographs | Graphics, logos | Everything |
| Compression | Lossy only | Lossless only | Both |
| Transparency | ❌ No | ✅ Yes (alpha) | ✅ Yes (alpha) |
| Animation | ❌ No | ❌ No | ✅ Yes |
| File Size | Medium | Large | Small (30% smaller) |
| Browser Support | ✅ 100% | ✅ 100% | ✅ 98% |
