About PNG to WebP Converter
The PNG to WebP Converter takes your PNG images and outputs smaller WebP files ready to drop into any modern website or app. WebP’s superior compression algorithm delivers the same visual quality at a fraction of the file size — which means faster page loads, lower bandwidth costs, and better Lighthouse scores without any extra design work.
PNG became the standard for lossless web images because it handled transparency and sharp edges better than JPEG. WebP does everything PNG does — lossless compression, full alpha transparency, sharp text and edges — while trimming 25–35% off the file size on average. Switching your PNGs to WebP is one of the most straightforward performance improvements you can make to a website, and with near-universal browser support, there is no longer a meaningful compatibility reason to stick with PNG for web delivery.
Free, no signup required, runs in any browser.
Frequently asked questions
WebP is a modern image format developed by Google that uses advanced compression to produce smaller files than PNG without sacrificing visual quality. WebP supports both lossless and lossy compression, transparency (alpha channel), and animation — making it a direct upgrade for most PNG use cases on the web.
WebP lossless compression typically produces files 25–35% smaller than equivalent PNG files. For images converted with lossy WebP compression, savings can reach 50–80% compared to PNG — with minimal perceptible quality difference for most images.
Yes. WebP is supported by all modern browsers including Chrome, Firefox, Safari (since version 14), Edge, and Opera. As of 2024, WebP has over 97% global browser support, making it safe to use as your primary image format for the web.
Lossless WebP conversion preserves full image quality — the result is visually identical to the original PNG. If the conversion uses lossy mode, there may be a subtle reduction in quality, but it is generally imperceptible at high quality settings. For logos, UI graphics, and screenshots, lossless conversion is ideal.
