About WebP Conversion
WebP is a modern image format developed by Google that provides superior lossless and lossy compression for images on the web. Using WebP, webmasters and web developers can create smaller, richer images that make the web faster.
Our tool allows you to convert images to WebP instantly in your browser. Because we process files locally, you get the speed of a desktop app with the convenience of a website—plus, your photos never leave your device.
Implementation Guide
How to Use WebP on Your Website
The best way to serve WebP images is using the HTML <picture> element. This ensures modern browsers load the lightweight WebP file, while older browsers automatically fall back to the original JPG or PNG.
<picture>
<source srcset="image.webp" type="image/webp">
<source srcset="image.jpg" type="image/jpeg">
<img src="image.jpg" alt="Description" width="800" height="600">
</picture>Browser Support
WebP is supported by 96%+ of browsers globally, including:
- Chrome 32+
- Firefox 65+
- Safari 14+ (macOS & iOS)
- Edge 18+
- Opera 19+
Quality & Optimization
Choosing the Right Quality Setting
- 100% (Lossless): Use for logos, icons, and screenshots with text. Preserves every pixel.
- 90-95% (Near-Lossless): Best for professional portfolios where quality is paramount.
- 80-85% (Recommended): The sweet spot for most web images. Significant size reduction (30-40%) with no visible quality loss.
- 70-75%: Good for thumbnails or social media preview images.
Common WebP Conversion Mistakes
- Using 100% for everything: Don't do this! 100% WebP can sometimes be larger than the original JPG. Stick to 80-85% for photos.
- Forgetting the Fallback: Always provide a JPG/PNG fallback for the ~4% of users on very old browsers.
- Double Compression: Avoid compressing an image that has already been heavily compressed. Start with the highest quality source possible.
Next Steps
Now that you have your optimized WebP images, you might need:
- Image Compressor: Squeeze even more savings (up to 80% more).
- Image Resizer: Resize them to the exact dimensions your website needs.
- Image to PDF: Compile your images into a document.
Why WebP Matters for SEO
Search engines (especially Google) prioritize user experience. A huge part of that is page load speed.
- Core Web Vitals: Large images slow down your LCP (Largest Contentful Paint). Switching to WebP is one of the easiest ways to fix a poor LCP score.
- Mobile Indexing: Most users browse on mobile. Smaller WebP files save data and load instantly on 4G/5G networks, reducing bounce rates.
- Future Proofing: Modern browsers all support WebP. It is the standard for the modern web.
Supported Formats
Our converter handles the most common image types:
- JPG to WebP: Shrink your photos for your blog or portfolio.
- PNG to WebP: Optimize logos and icons while keeping strict transparency.
- GIF to WebP: Make your animated memes load faster.
