Frequently Asked Questions (FAQ)
Do animations and slide transitions export to PDF?
PDF is a static page document format. The converter exports the finalized visual state of each slide, ensuring clean readability.
Are custom presentation fonts preserved?
Standard OpenXML font metrics are mapped to high-fidelity SVG or PDF font streams, preserving typography hierarchies.
Can I convert large slide decks with 100+ slides?
Yes. Memory streaming processes slides sequentially without exceeding browser memory limits.
Is my confidential slide deck kept private?
100% private. All processing occurs in local RAM; no slide content is ever transmitted to external servers.
