PNG to WebP — Smaller Files, Same Visual Quality
Convert PNG to WebP in your browser and shrink file sizes by 25–35%. Alpha channel preserved. No uploads, no signup, completely free.
How to Convert PNG to WebP
Drop Your PNG Files
Drag and drop one or more PNG files onto the converter, or click to browse. Batch PNG to WebP conversion is supported.
Choose Lossless or Lossy
Lossless WebP preserves every pixel — still smaller than PNG. Lossy lets you trade a tiny quality margin for even greater compression. Adjust quality from 1–100.
Convert in the Browser
Click convert. Encoding runs locally via WebAssembly — your pixel data never touches a server. No bandwidth spent uploading large PNG files.
Download Your WebP Files
Your PNG to WebP conversion is done. Save files individually or grab them all at once, then deploy to your web server or CDN.
Why Convert PNG to WebP
WebP was built for the web. Google designed it to deliver better compression ratios than PNG and JPEG without a perceptible hit to visual quality.
25–35% Smaller Files
Lossless WebP encodes the same pixel data as PNG but with a smarter compression algorithm. Typical real-world savings run 25–35% per image — meaningful bandwidth reduction at scale.
Alpha Channel Preserved
WebP fully supports transparency. Convert PNG images with soft shadows, rounded corners, or cutouts and the alpha channel carries over intact — no white halos, no fringing.
Lossless and Lossy Modes
Choose lossless for UI assets, icons, and screenshots where pixel-perfect accuracy matters. Switch to lossy for photos and illustrations to push compression ratios even further.
Core Web Vitals Impact
Images are the single biggest factor in LCP scores. Serving WebP instead of PNG directly reduces image payload, accelerating LCP and improving your Core Web Vitals without changing a pixel of layout.
Runs Entirely in Your Browser
Encoding is done by a WebAssembly build of libwebp running on your device. Nothing is uploaded. Ideal for sensitive assets, private screenshots, or bulk batches you don't want on a remote server.
Free, No Account Required
No signup, no subscription, no file size cap tied to a pricing plan. Convert PNG to WebP as many times as you need — forever free.
