PNG to WebP Converter

Convert PNG images to Google's WebP format directly in your browser — no upload,

no signup, no software installation required. WebP delivers 25–34% smaller files

than PNG at equivalent visual quality and fully supports alpha transparency, making

it the preferred format for web performance without sacrificing image quality.

Use the quality slider to control the output: 85% provides an excellent balance

for most web images. Higher settings (90%+) preserve more detail for hero images

and product photography. Lower settings (70–80%) shrink files further for

thumbnails and background images. Transparent pixels are preserved exactly —

unlike converting to JPEG.

All major browsers have supported WebP since 2020, covering over 96% of global

users. Batch conversion is fully supported — drop multiple PNG files at once and

download all WebPs in a single click. Processing runs entirely client-side using

the Canvas API.
