How to convert PPT to PPTX
- Add your .PPT file - drop it in the box above or click to browse.
- Convert it to .PPTX in a few seconds.
- Download your new .PPTX file.
What to expect
- VBA macros are silently stripped from a plain
.pptx- choose PowerPoint Macro-Enabled Presentation (.pptm) if the deck contains macros. - PPTX uses ZIP compression, so the converted file is typically 20-40% smaller than the original
.ppt. - Google Slides may shift complex layouts, custom fonts, or grouped objects; use PowerPoint or LibreOffice Impress when fidelity is critical.

libreoffice --headless --convert-to pptx *.ppt.Will the converted PPTX open on older versions of PowerPoint?
