WebP is powerful—but like any tool, it must be used correctly. Many website owners make mistakes that reduce performance instead of improving it. Here are 7 common mistakes to avoid when using WebP images.

1. Over-Compressing Images

Compressing too much can make images look blurry and unprofessional.
👉 Solution: Keep quality between 70–85% for best balance.

2. Forgetting Fallbacks

Older browsers (like Internet Explorer) don’t support WebP.
👉 Solution: Use plugins or code that serves JPG/PNG fallback versions.

3. Not Testing Core Web Vitals

Some people convert to WebP but never test performance.

4. Ignoring Image Dimensions

Uploading oversized WebP files wastes bandwidth.
👉 Solution: Resize images before converting.

5. Using Lossless WebP Everywhere

Lossless WebP creates bigger files.
👉 Solution: Use lossless for logos/graphics, lossy for photos.

6. Not Automating Conversion

Manually converting hundreds of images wastes time.
👉 Solution: Use plugins, scripts, or bulk converters.

7. Skipping Alt Text

WebP improves speed but doesn’t replace SEO basics.
👉 Solution: Always add descriptive alt text for images.

Conclusion

WebP is a game-changer, but only if you avoid these pitfalls. The right balance of quality, size, and SEO makes your site faster and more professional.
