Gamma to PowerPoint: why export quality drops and 3 real fixes
Gamma's .pptx export converts your beautiful web deck into a flattened PowerPoint file: animations vanish, text becomes images, fonts substitute, and editability collapses. Here's exactly what breaks, why it happens (architecturally), and 3 workarounds before you give up on PowerPoint output.

| Chart editability | Flattened | Native | Native | Native |
| Image layers separate | No | Yes | Yes | Yes |
| Fonts preserved | Substituted | Yes | Yes | Yes |
| Animations carry over | No | Limited | Yes | No |
| Layout fidelity | High (image-rendered) | High | High | High |
| VC-edit-ready | No | Yes | Yes | Yes |
Frequently asked questions
Gamma's renderer is web-native — text + layout are HTML/CSS, not slide objects. To preserve visual fidelity in PowerPoint, Gamma rasterizes the rendered HTML to image and embeds the image in a .pptx file. This is an architectural choice for fidelity, not a paywall limitation.
Mostly no. Text appears as image, so changing typos or numbers requires re-generating in Gamma and re-exporting. VCs and bankers who edit decks (red-lining financials, fixing comma errors) will be frustrated. Use SlideGMM or Beautiful.ai for VC-edit workflows.
Workaround 1: export to PDF (preserves visual quality, kills editability anyway). Workaround 2: export to PPTX then manually rebuild critical slides in PowerPoint (1-2 hours work). Workaround 3: switch to SlideGMM or Plus AI for the final draft — generate concept in Gamma, build deliverable elsewhere.
No. The flattening happens at the rendering layer, same on Free and Plus. Plus removes the watermark but the export-to-image architecture is identical.
Unlikely in the short term. The architectural decision is fundamental to Gamma's web-first design. Public roadmap and engineering blog posts have addressed the trade-off and chosen to optimize for web rendering, not PowerPoint editability.
