PNG to WebP
PNG keeps transparency but the files are large. WebP keeps transparency too, at a fraction of the size. PNG to WebP converts them in your browser.
Last updated: July 2026
PNG to WebP converts PNG images into Google's WebP format, which supports transparency like PNG but produces far smaller files — often 60–80% smaller for graphics. This tool re-encodes the image to WebP entirely in your browser, so nothing is uploaded.
🔒 Conversion runs in your browser — your image is never uploaded.
How to use PNG to WebP
