PPT to PPTX Converter
Upgrade your old PowerPoint presentations. Convert .ppt to the newer .pptx format for better security and features.
Why Convert PPT to PPTX?
The .ppt format was the standard until 2007, but today's .pptx format offers significant advantages. It uses XML for smaller file sizes, better data recovery, and improved security. Converting your old files ensures they remain accessible and editable in modern versions of PowerPoint, Google Slides, and Keynote.
Moving to PPTX also enables support for newer chart types, better smart graphics, and wider compatibility with mobile office apps.

Are macros preserved?
This converter focuses on the presentation content (slides). Macros (VBA) from .ppt files are typically stripped for security reasons during conversion to standard .pptx.
