JPG (q80)	180 KB	85% smaller
WebP (q80)	120 KB	90% smaller
WebP Lossless	450 KB	62% smaller

WebP consistently delivers 30–35% smaller files than equivalent-quality JPEG and 60–80% smaller than PNG.

Quality Comparison

JPG Quality Scale

• 90–100: Visually lossless, large files
• 70–85: Excellent quality-to-size ratio
• 50–70: Good for thumbnails
• Below 50: Visible artifacts

WebP Quality Scale

• 80–100: Visually lossless
• 60–80: Great ratio (recommended for most uses)
• 40–60: Acceptable for secondary content

At equivalent quality, WebP is always smaller than JPG.

Transparency (Alpha Channel)

PNG and WebP both support transparency. JPG does not.

Key difference: WebP with transparency is 25–35% smaller than PNG with transparency.

Animation

When to Use Each Format

Use JPG When

• Photographs and complex scenes
• Backward compatibility required
• Working with legacy systems
• Serving to very old browsers

Use PNG When

• Graphics with sharp edges (logos, icons)
• Images requiring transparency
• Screenshots and UI elements
• Archival/editing workflows

Use WebP When

• Modern web applications
• Need smallest file size
• Both lossy and lossless compression
• Transparency or animation needed
• Serving to modern browsers (97%+)

Recommendation

Use WebP as your default format with JPG/PNG fallback. This approach gives you:

• 30–35% smaller files than JPG
• 60–80% smaller files than PNG
• Full transparency support
• Animation support when needed
