Convert WebP to AVIF API

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.
