Convert PNG to WebP API

What it does

PNG to WebP Converter turns a PNG image into a WebP file. Send either a publicly accessible PNG URL or a PNG file upload, and get back either a binary WebP download or a signed URL, depending on the endpoint you choose.

Use the URL-based endpoints when your source image already lives on the web. POST /url/link returns a data field containing a URI for the converted file, while POST /url/download returns the converted file as binary content. If you already have the image in your request, POST /multi-part/link accepts a binary image and returns a data URI, and POST /multi-part/download returns binary WebP output.

This is useful for image optimization workflows where you need smaller, web-friendly assets without changing the source pipeline. For example, you can convert product images, thumbnails, or uploaded PNGs to WebP before storing them in your CDN or serving them to browsers.

The request schemas are minimal: the URL endpoints require url, and the multipart endpoints require image. Each endpoint also accepts an optional output query parameter.
