Frequently Asked Questions
How do I convert PNG to WebP online for free?
Upload your PNG files, click Convert, and download WebP output. All conversion happens locally in your browser — no account or upload required.
How much smaller is WebP compared to PNG?
WebP is typically 25–35% smaller than PNG for photographic images and up to 50% smaller for images with transparency, at the same perceptual quality. This directly reduces your page load time and improves Core Web Vitals scores.
Does PNG to WebP conversion preserve transparency?
Yes. WebP fully supports alpha channel transparency. When you convert a PNG with a transparent background, the transparency is preserved in the WebP output — making it ideal for logos, icons, and UI elements.
Is WebP supported by all browsers?
Yes — as of 2024, WebP is supported by all major browsers including Chrome, Firefox, Safari (since iOS 14/macOS 11), Edge, and Opera. It's now safe to use WebP as the primary format for all web images.
Should I replace all PNGs with WebP on my website?
For photographs and complex images, yes — WebP will be significantly smaller. For simple icons and logos, use SVG instead of either format. For raster logos and UI elements, WebP lossless is a good PNG replacement.
