Format Details
PPTX
PPTX is the default Microsoft PowerPoint presentation format since Office 2007, based on the Open XML standard and standardized by ISO/IEC. It stores slides, animations, transitions, speaker notes, embedded media, and themes in a compressed ZIP package of XML files. PPTX is the dominant presentation format in business and education worldwide, natively supported by Google Slides, LibreOffice Impress, Apple Keynote, and all modern presentation tools.
PDF (Portable Document Format) was created by Adobe in 1992 and has become the worldwide standard for sharing documents with precisely fixed layouts. It preserves fonts, images, vector graphics, and formatting identically across every operating system, device, and printer. PDF supports digital signatures, encryption, interactive forms, and embedded multimedia, making it essential for official documents, contracts, reports, and professional publications.
