## About

## What it does
WebP to AVIF Converter turns a WebP image into an AVIF file. Send a publicly accessible WebP URL or upload a WebP file, and get either the converted binary file back or a signed URL to the result.

Use the URL-based endpoints when your source image already lives on the web. The request body takes a single `url`, and you can set an optional `output` query value to name the returned file. If you prefer to upload directly, the multipart endpoints accept one `file` field containing the WebP image. In both cases, you choose whether the response is a downloaded binary or an object containing a `data` URL.

Use WebP to AVIF Converter when you need to store or serve images in AVIF for smaller file sizes and modern browser delivery, while keeping a WebP source in your pipeline. It fits image optimization jobs, media ingestion flows, and backend conversion steps where you want a predictable format change without extra processing logic.
