Discover the key differences between WebP and JPEG image formats. Learn which is better for web performance, image quality, and compatibility in 2024.
When it comes to choosing an image format for your website or digital project, WebP and JPEG are two of the most common options. But which one is better?
Let’s break down the differences and help you choose the right format for your needs.
What is WebP?
WebP is a modern image format developed by Google. It uses both lossy and lossless compression, meaning it can reduce file size significantly without a noticeable loss in quality. WebP also supports transparency (alpha channel) and animation, making it highly versatile for web use.
What is JPEG?
JPEG (or JPG) has been a standard image format since the 1990s. It uses lossy compression, which discards some data to reduce file size. JPEGs are widely supported and work well for photographs and detailed images—but they don’t support transparency or animation.
WebP vs JPEG: Key Comparisons
| Feature | WebP | JPEG |
|---|---|---|
| Compression | Lossy & lossless | Lossy only |
| File Size | Smaller | Larger |
| Image Quality | Higher at same file size | Lower at same file size |
| Transparency | Yes | No |
| Animation | Yes | No |
| Browser Support | Modern browsers only | All browsers |
| Editing Software | Limited (but improving) | Universal support |
When to Use WebP
- You want smaller file sizes to boost page speed.
- You’re building for modern browsers and care about performance.
- You need transparency or animated images.
- You’re optimizing for SEO and mobile performance.
When to Use JPEG
- You need maximum compatibility with older browsers or platforms.
- You’re dealing with legacy systems or software.
- You want quick edits using any image editor.
- You’re working with high-resolution photographs where slight quality loss is acceptable.

Final Verdict: Which is Best?
If you prioritize performance, quality, and smaller file sizes, WebP is the clear winner—especially for modern web design and mobile optimization. However, JPEG is still reliable for universal compatibility and ease of use.
Tip: Many websites now serve WebP by default but fall back to JPEG when needed. Using both formats strategically ensures the best experience for all users.
Conclusion
In the WebP vs JPEG debate, the best format depends on your goals. For cutting-edge web performance, choose WebP. For maximum compatibility and simplicity, stick with JPEG. Ideally, use both formats with responsive design techniques to cover all bases.
