Why convert PNG or JPG to WebP?
WebP routinely delivers 25–35% smaller files than comparable JPEG and often 50% or more savings versus PNG for photographic content, while keeping detail that looks identical at normal viewing sizes. That means faster uploads, quicker mobile pages, and lower bandwidth bills—without sacrificing the look of your images.
Lossless, lossy, and transparency
WebP supports both lossy compression (great for photos) and lossless compression (ideal when you need pixel-perfect graphics or text on flat colors). It also handles alpha transparency, so PNG-style cutouts and UI assets can shrink dramatically when converted to WebP.
Browser support in 2026 and PageSpeed
Every major browser now ships WebP support, so serving WebP is standard practice for new sites. Google PageSpeed Insights and Core Web Vitals reward lighter images because they improve Largest Contentful Paint (LCP) and overall page weight. Converting PNG and JPG sources to WebP is one of the highest-impact, lowest-effort optimizations you can make—and with this tool, conversion happens locally in your browser, with no server upload.
