- Skip AVIF for archival masters: lossy compression discards detail, so keep the GIF original.
- Keep a master copy: repeated exports stack small losses, so archive GIF before batch AVIF shares.
Limits
Starting point: GIF - 256-color animation with 1-bit transparency. Limited to 256 colors per frame, so gradients may band. Older viewers may not open it; keep a JPEG or PNG copy for sharing. Set the quality slider near 80-90 for AVIF photos from GIF, and keep dimensions matched to the source.
