How to Use This WebP Converter

Click the upload area or drag and drop your PNG or JPG files. You can select multiple images. The tool converts them in your browser and shows a preview with the new file size. Adjust the quality slider if you want to balance size and quality. Click Download WebP to save a single image or Download All to get a ZIP of all converted files. Your images are never sent to a server; conversion runs locally in your browser.

Why Convert Images to WebP?

WebP is a modern image format that often gives smaller file sizes than PNG or JPEG at similar quality. Smaller images mean faster page loads, better Core Web Vitals, and a smoother experience for users. Many browsers and CMSs support WebP; converting your images to WebP can reduce bandwidth and improve performance without losing visible quality.

When to Use WebP

Use WebP for website images, especially photos and graphics that are displayed on the web. Serve WebP to supporting browsers and keep PNG or JPEG as a fallback for older ones. Many CDNs and hosting platforms can do this automatically. For print or strict compatibility with very old systems, keep original PNG or JPEG. For logos or graphics with transparency, WebP supports alpha channels and often outperforms PNG in file size.

Frequently Asked Questions

Is WebP supported everywhere? All modern browsers support WebP. Older browsers (e.g. very old IE) may not. Use fallbacks (e.g. picture element with JPEG/PNG) if you need to support legacy browsers.

Are my images uploaded to a server? No. Conversion happens in your browser. Your files never leave your device.

What quality setting should I use? For photos, 80 to 85 often gives a good balance. For graphics or when you need maximum quality, use 90 to 100. Try a few settings and compare file size and appearance.

Can I convert WebP back to PNG or JPG? Yes, but you need a different tool. This converter only creates WebP from PNG or JPG. Keep originals if you might need them in another format later.
