Convert PNG images to WebP in seconds — smaller files, transparency preserved, right in your browser.
This tool converts PNG images to WebP format entirely in your browser. WebP typically produces significantly smaller files than PNG while still supporting a full alpha channel, so transparent areas of your PNG stay transparent in the output — a good default for web images where PNG was only chosen for its transparency support. A quality slider lets you balance file size against visual quality. Everything happens locally in your browser, so your image is never uploaded anywhere.
Drag and drop a PNG file, or click to browse.
Click Convert. Adjust the quality slider if you want a smaller or higher-quality file.
Save your WebP file to your device.
Your image is processed locally and never leaves your device.
