T42 to AVIF conversion is the process of transforming image files in the T42 format into the AVIF (AV1 Image File Format) container. This converts T42-encoded image data into AVIF-encoded images, enabling better compression efficiency and broader modern web compatibility while preserving image fidelity when configured correctly.
