About rendering PowerPoint to PDF
What this tool renders
Standard PowerPoint slides with text, embedded images, master-slide layouts, and embedded charts. Each slide becomes one PDF page sized to your deck's aspect ratio (16:9 default; auto-detected for non-standard). Output is a single PDF, one PDF page per slide.
When to use it
Sharing decks externally to reviewers without PowerPoint installed. Archiving presentations as PDFs for retention compliance. Distributing slide-by-slide PDF deliverables for offline annotation. Sending decks to clients who only open PDFs.
Privacy framing
Business presentations often carry financial figures, strategic plans, and client-confidential content. We surveyed ten reachable PowerPoint-to-PDF competitors — every one uploads your file to a server with TLS plus delayed deletion. Zero offer browser-only processing. pdfmundo runs the entire conversion locally.
What we don't render losslessly
PDF is a static format. Animations and slide transitions cannot be represented and are dropped on render. Embedded videos are omitted; the deck's poster frame remains. Custom fonts substitute to a Helvetica fallback when not in the standard set. Speaker notes are skipped by default — see the FAQ for the v1.1 option.
Render transparency
Every limitation that applied to your render surfaces as a per-slide warning chip — custom font substituted, animations dropped, transitions dropped, embedded video skipped, embedded chart rasterized, non-Latin text fallback, speaker notes dropped, master slide simplified. You see exactly which slides carried which constraint.
Workflow chain
After conversion, protect the rendered PDF with a password via /protect-pdf/. Or compress for email attachment via /compress-pdf/. Tool 30 (PDF → PowerPoint) is on the roadmap as a separate companion tool.
Frequently asked questions
- What kinds of presentations work best?
- Decks with standard fonts (Calibri, Arial, Helvetica), static slides without animations or transitions, and embedded raster images render with the highest fidelity. Slides with custom fonts, animations, embedded videos, or SmartArt still convert — the limitations surface as warning chips so you see exactly what was simplified per slide.
- Why might my slides look different?
- Rendering is deterministic but format-constrained. PDF cannot represent timed reveals, so animations and slide transitions are dropped. Custom fonts substitute to Helvetica when the font isn't in the pdf-lib standard set. Embedded videos render as their poster frame. Every applied substitution surfaces as a warning chip with the affected slide index.
- Can I convert legacy .ppt files?
- Not in v1. Legacy .ppt files use the pre-2007 binary OLE container — a different format from modern .pptx (OOXML ZIP). Open the .ppt in Office365 or LibreOffice and save as .pptx, then retry here. We may add .ppt support in v1.1 if the workflow surfaces demand.
- Can I convert encrypted .pptx files?
- Not in v1. Encrypted .pptx files use OOXML cryptographic packaging that we cannot unlock browser-side. There is no /unlock-pptx/ catalog tool today. Open the file in PowerPoint or LibreOffice, remove the password, save as a fresh .pptx, and retry here.
- Are speaker notes included?
- Speaker notes are skipped by default. Most users sharing decks publicly want notes excluded — they're presenter-private content. When notes are present, the conversion emits a speaker-notes-dropped warning chip per affected slide so the behavior is transparent. A v1.1 option to include notes as a caption below each slide image is on the roadmap.
- Are my files uploaded?
- No. Conversion runs entirely in your browser using JSZip (.pptx parse), html2canvas (slide render), and pdf-lib (PDF assembly). Your .pptx never leaves your device. Financial decks, strategic plans, and confidential client material stay local on your machine.
