Making Your Decision
Still not sure? Answer this question:
Do you need to edit the presentation after export?
Choose PPTX Mode if:
- • You need to make changes after export
- • You're collaborating with a team
- • You want to customize colors or fonts later
Choose Image Mode if:
- • Visual impact is your top priority
- • You won't need to make edits
- • You want unique, AI-generated imagery
Practical choice guide
If you want the fastest rule of thumb, these two principles are usually enough:
Choose PPTX first
If the deck will still be revised by you, your team, or a client, choose PPTX first. It is better for rewriting text, adjusting layout, updating numbers, and collaborative review.
Choose Image first
If the deck is mainly about final-stage visual impact, cover-page quality, or on-stage presentation, and you do not expect further edits after export, choose Image.
