Everything you need to know about converting PNG images to WEBP format.
What is a PNG to WEBP converter?
A PNG to WEBP converter is an online tool that transforms PNG images into the WEBP format. WEBP is a modern image format developed by Google that provides superior compression — producing files that are 26% smaller than PNG at equivalent quality. This converter runs entirely in your browser, so your images never leave your device.
Is this PNG to WEBP converter free to use?
Yes, 100% free with no limitations. There's no sign up, no watermarks on output files, and no conversion limits. You can convert as many PNG images to WEBP as you need, forever, at no cost.
Will transparency remain after conversion?
Yes! Unlike JPG, WEBP supports full alpha-channel transparency — just like PNG. When you convert a PNG with a transparent background to WEBP, the transparency is preserved perfectly. This is one of the biggest advantages of converting to WEBP instead of JPG.
Why is WEBP better for websites?
WEBP files are 26% smaller than PNG at equivalent quality, which means faster page loads, lower bandwidth costs, and a better user experience. Google uses page speed as a ranking factor, so WEBP images can directly improve your SEO. They also help with Core Web Vitals metrics like Largest Contentful Paint (LCP).
Can I convert PNG images on mobile devices?
Absolutely. This converter is fully responsive and works on any modern smartphone or tablet browser. Simply open the page, upload a PNG from your photo gallery, adjust the quality, and download the WEBP file directly to your device.
Are uploaded images stored permanently?
No — never. All conversion happens locally in your browser using the HTML5 Canvas API. Your images are never uploaded to any server. When you close the tab or convert a new image, the previous data is gone permanently. Nothing is stored, logged, or accessible to anyone.
Does WEBP support transparent backgrounds?
Yes! WEBP supports full alpha-channel transparency, making it a true replacement for PNG. You get the same transparency capabilities as PNG — transparent backgrounds, semi-transparent overlays, and alpha blending — all at a significantly smaller file size. This is what makes PNG to WEBP such a powerful conversion.
Which browsers support WEBP images?
WEBP is supported by over 97% of browsers globally, including Chrome, Firefox, Safari (iOS 14+ and macOS Big Sur+), Edge, Opera, and all Chromium-based browsers. The only notable exception is very old browser versions. For maximum compatibility, you can use the <picture> element with a PNG fallback.
