Convert WebP to JPEG API

Hosted on ApyHub

What it does

WebP to JPEG Converter turns WebP images into JPEG files. You can send a publicly accessible image URL and get back a signed download URL, or upload a file with multipart form data and either download the converted JPEG directly or receive a signed URL.

Use the URL-based endpoints when the image already lives on a public asset host. Send url in the request body, and the response returns data as a URI. Use the multipart endpoints when you have the file locally and want either a binary JPEG response or a signed URL for later download.

This is a straightforward fit for pipelines that need JPEG output for older browsers, CMS imports, email templates, or systems that do not accept WebP. Keep the conversion step isolated, and pass the converted image into the rest of your workflow without adding custom image handling code.

WebP to JPEG Converter keeps the interface narrow: the request body contains either url or file, and the response is either a binary file or a data URI, depending on the route you choose.
