JPEG has been the king of image formats for over 30 years. But in 2010, Google introduced WebP, promising 25-35% better compression with similar quality. Now in 2026, which format should you use? Let's compare them in detail.
Quick Comparison Table
| Feature | JPEG | WebP |
|---|---|---|
| File Size | Baseline | 25-35% smaller |
| Quality | Good | Better at same size |
| Transparency | ❌ No | ✅ Yes |
| Animation | ❌ No | ✅ Yes |
| Browser Support | 100% | 96% |
What is JPEG?
JPEG (Joint Photographic Experts Group) was created in 1992. It uses lossy compression, which means it reduces file size by discarding some image data. It's perfect for photographs and complex images but doesn't support transparency.
What is WebP?
WebP was developed by Google based on the VP8 video codec. It supports both lossy and lossless compression, transparency (like PNG), and even animation (like GIF) – all in one format.
File Size Comparison
We tested the same image at similar quality levels:
- JPEG (80% quality): 245 KB
- WebP (80% quality): 168 KB (31% smaller)
- JPEG (90% quality): 412 KB
- WebP (90% quality): 289 KB (30% smaller)
Real-World Impact
For a website with 100 images, switching from JPEG to WebP can save 10-15 MB per page load. This means faster loading times and better SEO rankings.
Quality Comparison
At the same file size, WebP consistently looks better than JPEG. It has fewer artifacts and better detail retention, especially in high-contrast areas.
