What is PPT?

PPT is Microsoft PowerPoint's legacy presentation format, used as the default from PowerPoint 97 through PowerPoint 2003. It stores slides, text, images, animations, and multimedia in a proprietary binary structure.

While PPT has been superseded by PPTX since Office 2007, billions of legacy PPT files still exist in corporate archives, educational institutions, and personal collections. Converting these files ensures continued accessibility and modern feature support.

PPT files can contain complex presentations with animations, transitions, embedded media, and speaker notes, making them important to preserve correctly during conversion.

Why Convert PPT Files?

Converting PPT files addresses several important needs:

  • Modernization – Convert to PPTX for smaller files, better security, and modern PowerPoint features
  • Universal sharing – PDF format lets anyone view presentations without PowerPoint
  • Image extraction – Convert slides to JPG or PNG for use in other applications
  • Open standards – ODP format works with LibreOffice Impress
  • Video creation – Some tools convert presentations to video format
  • Legacy support – Convert modern files TO PPT for users with older Office

Convert PPT to Other Formats

Upgrade your legacy PowerPoint files to modern formats:

PPT to PPTX

The most important conversion. Upgrade to the modern PowerPoint format for smaller files, better security (no macros by default), and full compatibility with current PowerPoint versions.

PPT to PDF

Create professional PDF documents from your presentations. Perfect for sharing with anyone regardless of their software, or for printing handouts.

PPT to JPG

Convert slides to JPEG images. Each slide becomes a separate image file, perfect for sharing on social media, websites, or embedding in documents.

PPT to PNG

Export slides as PNG images with transparency support. Ideal for high-quality graphics or slides with transparent elements.

PPT to ODP

Convert to OpenDocument Presentation format for editing in LibreOffice Impress or other open-source presentation software.

PPT to TXT

Extract all text content from your presentation slides. Useful for content repurposing or accessibility purposes.

Convert Other Formats to PPT

Create legacy PowerPoint files for older Office compatibility:

PPTX to PPT

Downgrade modern PowerPoint files for compatibility with PowerPoint 2003 and earlier. Essential when sharing with users who have older Office installations.

PDF to PPT

Transform PDF presentations back into editable PowerPoint slides. Useful for recovering presentations saved only as PDF.

ODP to PPT

Convert LibreOffice Impress presentations to PowerPoint format for sharing with Microsoft Office users.

Images to PPT

Create presentations from image files. Each image becomes a slide, useful for photo slideshows or converting visual content to presentations.

Pro Tip

When converting old PPT files, check for embedded fonts. Legacy presentations often used fonts that may not be available on modern systems. Converting to PDF preserves the appearance even if fonts are missing.

Common Mistake

Assuming PPT and PPTX are interchangeable. PPT is a legacy format with security risks and larger file sizes. Always use PPTX for new presentations and convert old PPT files when possible.

Best For

PPT conversion is essential for modernizing legacy presentations from archives, old systems, or shared drives. Convert to PPTX for continued editing or PDF for sharing.

Not Recommended

Don't use PPT for new presentations. The format has security concerns with macros and produces larger files. Use PPTX for all new presentation work.
