How to use this tool

  1. Upload your PNG files

    Drag and drop PNG images, including those with transparent backgrounds. The converter supports batch processing of multiple files at once.

  2. Choose your quality level

    For web images, 80–85% quality usually produces the best size-to-quality ratio. For artwork or images with text, try 90%+. WebP's compression is much more efficient than PNG, so even at 90% you'll see significant size savings.

  3. Convert

    The browser encodes each PNG as WebP using the WebAssembly version of Google's libwebp encoder. Transparency is fully preserved in the output.

  4. Download and deploy

    Drop the WebP files directly into your website or project. All major browsers have supported WebP since 2020. Download as ZIP if converting in bulk.
