About converting PPT to PPTX
PPT and PPTX solve different problems, which is why this conversion is so common. Our converter reads the structure of your PPT file and rebuilds it as a valid PPTX file rather than simply renaming it, so the result opens cleanly in the apps you already use.
PPT is the older binary presentation format from Microsoft PowerPoint. PPTX is the presentation format used by Microsoft PowerPoint.
The converter sits in our document converters toolkit alongside PDF, DOCX, DOC, XLSX, XLS, PPTX, PPT, TXT, RTF, ODT, ODS, ODP, CSV, HTML and more. Nothing is installed, nothing is stored, and the output carries no watermark.
