PNG to WebP Converter
Upload a PNG image and convert it to WebP format in your browser. WebP is a modern image format developed by Google that typically produces files 25-35% smaller than PNG at comparable visual quality, while still supporting transparency.
A quality slider lets you balance file size against visual fidelity — 0.85 is a good default. At quality 1.0, WebP produces near-lossless output that's still smaller than PNG. This makes WebP ideal for web pages, where faster loading times directly improve user experience and SEO.
The conversion runs entirely in your browser using the native Canvas API. Nothing is uploaded to a server.

Frequently asked questions
Does WebP support transparency like PNG?▼
Yes — WebP supports alpha channel transparency, so transparent areas in your PNG are preserved in the WebP output. This makes it a direct replacement for PNG on the web with better compression.
Is there quality loss when converting to WebP?▼
At quality settings below 1.0, WebP uses lossy compression similar to JPG. At quality 1.0, WebP is near-lossless. The default setting of 0.85 produces files significantly smaller than PNG with imperceptible quality differences for most images.
Which browsers support WebP?▼
All modern browsers support WebP — Chrome, Firefox, Safari (14.1+), Edge, and Opera. If you need to support very old browsers, stick with PNG or JPG.
