Shrink website images 25–70% with transparency preserved — bulk conversion, no upload
100% private — files are converted inside your browser and never uploaded to any server.
WebP files are typically 25–70% smaller than equivalent PNGs while keeping full quality and — importantly — preserving transparency. For websites, that means faster page loads, better Core Web Vitals scores and lower bandwidth bills. Google PageSpeed Insights explicitly recommends serving images in “next-gen formats” like WebP, and every modern browser (Chrome, Firefox, Safari, Edge) supports it.
Select one or many PNG files above — logos, screenshots, UI assets, product images — and each converts to WebP with its own download button. Bulk conversion in one batch makes it practical to migrate a whole image folder before a site launch.
Keep PNG for images that must be edited again later (WebP re-encoding is lossy at default settings), for favicons targeting very old browsers, and for print workflows that don't accept WebP. For everything served on the web, WebP is the better choice. As always here, conversion runs in your browser — files are never uploaded.
