PDF is the universal fixed-layout document format — it renders identically across viewers, preserves fonts and formatting, and is the accepted-by-default format for invoices, contracts, government uploads, academic submissions, and portfolio work. Convert to PDF when the receiving system explicitly wants PDF or when the layout must not shift.
PPTX stores slides as XML-defined layouts with text boxes, shapes, images, and animations. PDF conversion renders each slide as a fixed page, embedding fonts, rasterizing effects, and flattening animations to their static state. Slide transitions, embedded videos, and interactive elements are lost — only the visual appearance of each slide is preserved. Speaker notes can optionally be included as a separate section or excluded entirely.
Convert PPTX to PDF for distributing presentations as read-only documents — handouts for attendees, archival of completed presentations, or sharing with people who don't have PowerPoint. PDF ensures consistent rendering across all devices and prevents accidental modification.
PPTX (PowerPoint Open XML Presentation) is the default file format for Microsoft PowerPoint 2007 and later. It replaced the older binary PPT format with a modern ZIP-based XML architecture that produces smaller files, better data recovery, and improved interoperability with other applications. PPTX files store slides, speaker notes, handouts, animations, transitions, and embedded media in a structured package.
PPTX is natively supported by Microsoft PowerPoint, Google Slides, Apple Keynote, LibreOffice Impress, and most modern presentation tools. The format supports SmartArt, charts, embedded video and audio, slide master templates, and real-time co-authoring through Microsoft 365. PPTX is the global standard for business presentations, lectures, training materials, and conference talks.
