01
ORF is a lossless format that prioritizes fidelity over size. Converting to AVIF introduces modern compression that typically reduces file size by an order of magnitude with no perceptible difference at normal playback or viewing.
02
AVIF is accepted by a wider range of image viewers, editors, and content systems than ORF. The conversion removes a recurring compatibility friction without changing what the file actually contains.
03
AVIF files are typically smaller than their ORF counterparts, which reduces hosting, transfer, and storage costs at scale. The savings compound when serving the same content to many recipients.
