CometPDFDownload

Convert PowerPoint to PDF offline.

CometPDF converts PPT and PPTX files to PDF on Windows. When PowerPoint is available, it uses the native export path. If not, the PPTX fallback keeps slide aspect ratio and creates a PDF page for each slide.

This is not an online converter. CometPDF is a Windows app for local PowerPoint to PDF conversion.
