เกี่ยวกับการแปลง PPS เป็น PPTX
PPS is a legacy PowerPoint Slide Show file (binary BIFF format, PowerPoint 97-2003) that auto-plays as a slideshow when opened. PPTX is the modern PowerPoint format (OOXML, introduced with Office 2007) that opens in editing mode and supports advanced features like SmartArt, improved charts, better media embedding, and smaller file sizes through ZIP compression.
Converting PPS to PPTX upgrades the legacy slideshow to the modern editable format, unlocking editing capabilities and modern PowerPoint features while changing the open behavior from slideshow to edit mode.
ทำไมต้องแปลง PPS เป็น PPTX
Legacy PPS files are limited by the PowerPoint 97-2003 feature set — maximum 2GB file size, limited chart types, no SmartArt, and no modern media embedding. Converting to PPTX modernizes the file while also making it editable (PPS opens as slideshow, PPTX opens in edit mode).
PPTX is the current standard for presentation files. Cloud platforms (OneDrive, Google Slides, SharePoint), modern collaboration tools, and current PowerPoint versions all handle PPTX as their primary format. Converting legacy PPS archives ensures continued compatibility with current tools.
กรณีการใช้งานทั่วไป
- Modernize legacy PPS slideshow archives to current PPTX format for cloud compatibility
- Convert PPS files to editable PPTX for content updates in modern PowerPoint
- Upgrade PPS training materials to PPTX for enhanced media embedding and SmartArt
- Migrate PPS kiosk presentations to PPTX for maintenance in current Office versions
- Convert PPS corporate archives to PPTX for SharePoint and OneDrive compatibility
วิธีการทำงาน
LibreOffice opens the PPS binary file and exports as PPTX OOXML. The conversion transforms binary BIFF slide records into XML-based Open XML markup within a ZIP container. Slide content, text, shapes, images, charts, and formatting are mapped from binary structures to their XML equivalents. Master slides and layouts are converted to PPTX slide masters. Animations and transitions are mapped to their OOXML equivalents. File size typically decreases due to ZIP compression.
คุณภาพและประสิทธิภาพ
Most slide content converts accurately. Text, images, shapes, and basic formatting are preserved. Some legacy effects or specific PowerPoint 97-2003 features may render slightly differently in the modern format. Complex animations may need verification. Font rendering is generally improved in PPTX. Test the converted file in PowerPoint to verify visual fidelity.
