Convert WebP to AVIF

What it does

WebP to AVIF Converter turns WebP images into AVIF files. Send a public WebP URL or upload a WebP file as multipart form data, and get back either the converted binary file or a signed download URL.

Use the URL-based endpoints when the source image is already hosted elsewhere. Send url in the request body, and optionally include output as a query parameter when you want a named output. If you prefer to upload directly, use the multipart endpoints with file and the same optional output parameter.

Choose the download variants when your app needs the AVIF file immediately. Choose the link variants when you want a signed URI for later retrieval or to pass the converted image to another service without handling the binary response yourself.

This fits image pipelines where you need smaller, modern image assets for web delivery, CDN processing, or storage migration from WebP to AVIF.
