What Is WebP and Why Convert to It?
WebP is a modern image format developed by Google that supports both lossy and lossless compression, along with transparency and animation. For typical photos and UI graphics, WebP produces files 25–80% smaller than PNG or JPEG at equivalent perceived quality — speeding up page loads and reducing bandwidth costs.
All modern browsers now support WebP (Chrome, Firefox, Safari, Edge, Opera), covering over 97% of web users. Converting your existing PNG or JPG assets to WebP is one of the highest-impact, lowest-effort performance optimizations you can make for any website.
How to Convert Images to WebP
- Upload your image — drag and drop PNG, JPG, or any supported format into the upload area.
- Set quality — the slider defaults to 80%, which works well for most web images. Lower for smaller files, higher for sharper output.
- Download WebP — the output format is set to WebP automatically. Save individually or batch download as ZIP.
WebP vs PNG vs JPG — When to Use Each
WebP is the best all-around choice for web images. It handles photos (like JPG) and transparency (like PNG) in a single format with smaller file sizes. Use PNG when you need maximum compatibility for pixel-perfect graphics. Use JPG for legacy systems that do not support WebP. For more detail on when each format wins, read PNG vs JPG vs WebP.
WebP for Core Web Vitals and SEO
Google PageSpeed Insights and Core Web Vitals reward lighter images because they improve Largest Contentful Paint (LCP) and reduce total page weight. Switching from PNG/JPG to WebP is consistently recommended by Lighthouse audits. This tool lets you convert locally — no server upload needed — so your original files stay private.
