Frequently Asked Questions: PNG to WebP

Why should I convert PNG to WebP? ▼
The main reason is web performance. WebP offers up to 30% better compression than PNG while maintaining the same visual quality and transparency support. This results in faster page loads and improved SEO rankings.
Do I lose transparency when converting PNG to WebP? ▼
No. Unlike the JPG format, WebP fully supports the alpha channel (transparency). Your logos and graphics will keep their transparent backgrounds while significantly reducing their file size.
Is WebP compatible with all browsers? ▼
Yes, currently WebP is compatible with over 96% of modern browsers, including Chrome, Firefox, Safari, and Edge. It is the recommended standard by Google for web images.
Does WebP support animations like GIF? ▼
Yes, and better. WebP supports animations with 24-bit color and transparency (alpha), unlike GIF's 8-bit limit. Plus, animated WebP files are significantly smaller than their GIF or APNG counterparts.
Does conversion affect color quality? ▼
Virtually no. WebP supports ICC color profiles and is natively capable of maintaining visual fidelity indistinguishable from the original to the human eye, but eliminates redundant data that only takes up unnecessary space.

How does PNG to WebP conversion work?

When you convert PNG to WebP, you are migrating from a lossless compression format to one that is much more optimized for the web. WebP uses block-based pixel prediction, which allows it to represent gradients and textures with far fewer instructions than the PNG standard.

Our tool uses WebAssembly to process your files directly on your machine. This ensures that the conversion is instant, private, and secure, as your images never leave your browser. The result is an image ready for the web, with transparent backgrounds if needed, but with a drastically reduced file size.
