How do I convert a PNG to WEBP?

Upload your PNG file, select WEBP as the output format, choose lossless or lossy mode, and click Convert. If you want the best quality, use lossless mode; if you want a smaller file, adjust the quality slider. Download the WEBP file once done.

Why should I use WEBP over PNG for web images?

WEBP offers superior compression, yielding file sizes 25–34% smaller than PNGs with the same visual quality. It supports transparency and animation, and all major browsers now support it. This reduces page load times and saves bandwidth.

What happens to transparency and color profiles when converting PNG to WEBP?

WEBP supports alpha transparency just like PNG, so transparent areas remain transparent. ICC color profiles are preserved, but lossy compression can introduce chroma subsampling, leading to slight color shifts. Resolution stays identical. For exact pixel data, choose lossless WEBP compression.
