Animated, sequence, or multipage inputs need explicit frame/page handling.
Converting HEIC to TIFF decodes the source image and writes a TIFF output. Use this route when TIFF is a better fit for compatibility, file size, editing, or delivery.
Quality behavior depends on TIFF compression: depends.
Choose conversion targets based on TIFF compression, transparency, animation, metadata, and compatibility requirements.
Known metadata support: Exif, XMP, HEIF item properties, thumbnails, derived images.
