Technical Specifications & Codec Breakdown
PPTX vs. PDF for Presentations
PPTX is built for editing slide masters, animations, and presenter notes. But if you are presenting on someone else's laptop, always bring an exported PDF backup - PDF guarantees that slide typography and graphics look identical on any projector.
Embedded Media & File Size Bloat
Presentations balloon to hundreds of megabytes when high-resolution images and videos are pasted onto slides. Converting embedded slide media to compressed web standards dramatically slashes deck file size without losing projection clarity.
