PNG to WEBP
Upload a PNG file, tune the WebP quality when needed, and download a smaller web-ready image with transparency preserved where possible.
PNG to WebP is useful for screenshots, UI elements, icons, and product graphics that need smaller file sizes on websites.
The conversion runs locally in your browser, so unfinished design assets and private screenshots stay on your device.
WebP is useful when a PNG needs to load faster on a website or take less storage while keeping transparency. This page accepts PNG only and always produces WebP, so the output cannot be changed accidentally.
The quality control affects compression and visible detail. Transparent pixels are encoded with a separate high-quality alpha channel, but you should still inspect soft shadows and semi-transparent edges after conversion.
Large screenshots, interface graphics and illustrations often shrink well. Tiny icons, images already optimized for the web, and assets that must remain byte-for-byte lossless may benefit less from conversion.
