Convert PNG to WebP — Smaller Files, Same Quality

WebP routinely delivers 25–80% smaller files than PNG for photographic content while keeping detail that looks identical at normal viewing sizes. That means faster page loads, quicker mobile experiences, and lower bandwidth costs — without sacrificing the look of your images.

How to Convert PNG to WebP Online

  1. Upload your PNG — drag and drop into the upload area, or click to browse. You can upload multiple files at once.
  2. Set quality — 80% is ideal for most web images. Lower for smaller files, higher for maximum fidelity.
  3. Download WebP — output format is set to WebP automatically. Save individually or batch download as ZIP.

WebP Features: Lossy, Lossless, and Transparency

WebP supports both lossy compression (great for photos) and lossless compression (ideal for pixel-perfect graphics). It also handles alpha transparency, so PNG-style cutouts and UI assets shrink dramatically when converted. This makes WebP a true all-in-one replacement for both PNG and JPG on the web.

WebP for Core Web Vitals and SEO

Every major browser now supports WebP (97%+ coverage). Google PageSpeed Insights and Lighthouse consistently recommend switching to WebP because lighter images improve Largest Contentful Paint (LCP) and reduce total page weight. Converting your PNG assets to WebP is one of the highest-impact, lowest-effort performance optimizations available.
