WebP is an image format developed by Google and first released in 2010. It was designed from the ground up for the modern web, using advanced compression techniques derived from the VP8 video codec. WebP supports both lossy and lossless compression, alpha transparency, and even animation — effectively replacing PNG, JPG, and GIF with a single, more efficient format.
Google's own testing shows that lossless WebP images are 26% smaller than equivalent PNGs, and lossy WebP images are 25–34% smaller than comparable JPGs at the same perceptual quality. This makes WebP the recommended format for web performance optimization, directly impacting Core Web Vitals scores and search engine rankings.
Quick & easyYour images are never uploaded to any server. The entire PNG-to-WebP conversion runs locally in your browser using the HTML5 Canvas API. Whether you are optimizing product images, company logos, or personal photos, everything stays on your device.
Client-side processing means zero upload wait time, no server queue, and no risk of your assets being stored, cached, or accessed by third parties. When you close or refresh the page, all converted files are purged from browser memory instantly.
