Can upgrade from old to modern formats

Will it upgrade a JPEG to a modern format like WebP or AVIF?

Introduction

Just as automatically sending modern formats should be expected, we also expect that those using browsers that don’t support modern formats do not get an unnecessarily broken experience. If a WebP/AVIF image is explicitly requested, but would not be able to be rendered based on the Accept header, then the response should be “downgraded” to a supported image format.

The Test

Does an explicit request for a JPEG automatically respond with a WebP/AVIF image based on the Accept header?
