PNGs are great for transparent logos and crisp graphics, but their lossless nature means they often bloat to 1MB or more. Modern web standards favor WebP, a Google-developed image format that retains transparency while cutting file size by 30% to 70%.
By converting your PNG assets to WebP using ImgReducer, your website loads significantly faster, improving Google Core Web Vitals (LCP) and lowering bounce rates.
The conversion happens entirely in your browser using native HTML5 Canvas encoding, providing maximum speed and zero privacy leaks.
WebP retains alpha channels so your transparent logos and icons remain flawless.
Dramatically smaller file sizes compared to traditional PNG compression.
