About the PNG to WebP Converter
WebP typically produces smaller files than PNG at the same visual quality, which means faster page loads — a big deal for site speed and SEO. Unlike JPG, WebP still supports full transparency, so it's a natural upgrade path for PNGs that rely on an alpha channel.
This tool converts your PNG straight to WebP in your browser, with transparency intact. There's no upload to a server — your image never leaves your device, and the conversion is essentially instant even for larger files.
