## About

## What it does
WebP to PNG Converter turns a WebP image into a PNG, either from a multipart file upload or from a publicly accessible image URL. You can choose to download the converted file directly or receive a signed URL in the response.

Use the multipart endpoints when you already have the image in your request body: send `file`, and optionally set `output` as a query parameter. Use the URL endpoints when the source image is already hosted elsewhere: send `url` in the body, plus the optional `output` query parameter. The download endpoints return binary PNG data. The link endpoints return an object with a `data` field containing a URI.

This is a fit for image pipelines that need PNG output for browser compatibility, design tooling, or downstream processing that does not handle WebP reliably. It is also useful when you need to convert remote assets without downloading and re-uploading them yourself.
