PPSX at a glance
PPSX
Convert to PPSX when the deck should behave like a presentation on open, such as self-running briefings, classroom slide packs, customer demos, or event displays.
It is appropriate when the content remains PowerPoint-native but the primary user action is playback rather than editing.
If users are expected to revise the deck, PPTX is usually the better target.
DFF at a glance
DFF
Convert to DFF when preserving SACD-derived masters, moving 1-bit DSD recordings between specialist audio tools, or maintaining an audiophile archive that prioritizes native DSD playback.
It is most useful in high-resolution music preservation and studio workflows that stay within the DSD ecosystem.
