What is PNG to WebP conversion?
PNG to WebP conversion changes a Portable Network Graphics image into WebP. PNG is a lossless raster format designed for the web. It preserves every pixel exactly and supports full alpha-channel transparency, making it the standard choice for graphics, logos, and screenshots. WebP is a modern image format developed by Google that supports both lossy and lossless compression, transparency, and animation — typically producing smaller files than JPG or PNG at comparable quality. Converting between the two lets you pick whichever format best fits where the image is headed next.
