How PNG/JPG to WebP Converter works
Load the PNG or JPG
The image is decoded into an Image element and its real pixel dimensions are measured.
Re-encode on Canvas
The image is painted onto a canvas and exported as WebP at your chosen quality. WebP typically lands 25–35% below an equivalent JPG.
Download the WebP
You get a .webp file at the same pixel dimensions, plus the percentage of space saved.
