## About

## What it does
JPEG to WebP Converter turns a JPEG or JPG image into a WebP file. Send either a public image URL or a binary image upload, and choose whether you want the result returned as a downloadable file or as a signed URL in the response.

Use the URL-based endpoints when the source image already lives online, or the multipart endpoints when you're uploading a local file. The request body only needs `url` for URL conversions or `image` for multipart conversions. If you need a named output, pass `output` as a query parameter.

The response matches the delivery mode you choose: the download endpoints return binary WebP content, while the signed-URL endpoints return a JSON object with a `data` field containing a URI. That makes this service a good fit for image pipelines, CMS uploads, storage optimisation, and client-side delivery where smaller WebP assets reduce transfer size.
