About this tool
WebP typically produces 25–35% smaller files than JPG at the same visual quality, which is why it's a go-to format for web performance and better Core Web Vitals. This converter re-encodes your images to WebP using the browser's native Canvas encoder, entirely on your device — nothing is uploaded. Use it to optimize images before publishing to a website, CMS or app. If a destination doesn't accept WebP yet, convert to JPG instead with our PNG to JPG / compressor tools.
