Convert JPEG to WebP API

What it does

JPEG to WebP Converter turns a JPEG or JPG image into a WebP file. Send either a binary image upload or a publicly accessible image URL, and get back the converted result as a file download or a signed URL, depending on the endpoint you use.

Use the multipart endpoints when you already have the source image in your app or form upload flow. Use the URL endpoints when the image already lives somewhere public and you want to convert it without downloading it first. In both cases, the request only needs the source image input plus the optional output query parameter.

The response is simple and matches the delivery mode: download endpoints return the converted WebP as binary data, while signed-URL endpoints return a JSON object with a data field containing a URI. That makes it easy to plug JPEG to WebP Converter into image pipelines, content delivery workflows, or storage backends that prefer WebP for smaller file sizes and browser support.
