Convert PNG to WEBP online, free

PNG is lossless and universal, but it makes heavy files. Converting PNG to WEBP keeps the same image — transparency and all — at a much smaller size, so pages load faster and uploads go quicker. Your files are processed securely and never stored.

Smaller files, same transparency

WEBP supports both lossless and lossy compression plus a full alpha channel, so your transparent logos, icons and screenshots stay transparent while shedding weight. Lossless WEBP is typically around 25% smaller than PNG, and lossy WEBP can be far smaller still — ideal for the modern web.

Format details

PNG is a lossless raster format that supports full transparency (alpha channel). It keeps every pixel intact, making it the go-to choice for logos, icons, screenshots and any graphic with sharp edges or text.
