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.
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.
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.
PNG opens in every web browser and image viewer, plus editors like Photoshop, GIMP, Preview (Mac) and Photos (Windows).
WEBP is a modern format from Google that uses both lossy and lossless compression to make images roughly 25–35% smaller than JPG or PNG at similar quality. It supports transparency and animation, and is built for fast-loading websites.
WEBP opens in all modern browsers (Chrome, Edge, Firefox, Safari) and recent versions of Photoshop, GIMP and most image viewers.
