About PNG to WebP conversion
PNG (Portable Network Graphics) is a lossless raster format that compresses images without discarding any pixel data. WebP is a modern image format developed by Google that delivers smaller files than JPG or PNG at the same visual quality, using both lossy and lossless compression modes.
Converting PNG to WebP trades some image data for a dramatically smaller file. WebP is ideal for web pages and apps where fast loading and bandwidth savings are priorities. The quality slider lets you choose your own balance: higher values (90-100) are visually lossless for most photos, while lower values shrink the file further. If your PNG contains transparency, the transparent areas will be filled with a solid white background in the WebP output — WebP does not support an alpha channel.
The converter on this page runs entirely in your browser — your image is never sent to a server. It is completely free with no sign-up, no watermark, and no daily limit. Just drop your PNG, adjust settings if needed, and download your WebP in seconds.
