PPTX at a glance
PPTX
Convert to PPTX when the output needs to remain an editable presentation.
It is the right target for sales decks, training materials, investor presentations, conference talks, board packs, and internal briefings where teams will rearrange slides, update branding, swap charts, or localize content later.
Use PPTX when presenter notes, slide masters, animations, and embedded media need to survive.
If the deck is finished and should not change, PDF is often better; PPTX is for ongoing presentation workflows.
