Free online PPS to PPTX converter

A recipient who needs to revise slides or use software that expects an editable presentation may need a PPS file saved as PPTX. PPS usually opens as a slideshow, while PPTX normally opens in the editing interface.

What the PPS format is

.pps is Microsoft PowerPoint’s legacy binary PowerPoint Show format. It stores presentation slides, but opening it usually starts the slideshow instead of opening the editing interface. PPS is often used to distribute finished presentations; the format itself does not prevent editing.

What the PPTX format is

.pptx is the Office Open XML presentation format used by current PowerPoint versions and many other presentation programs. It is intended for working with and sharing editable presentations, and is generally more suitable than PPS when a recipient needs to revise slides.

Offline with desktop software

LibreOffice Impress is a free option for Windows, macOS, and Linux. Open the file using File → Open, then choose File → Save As and select the PowerPoint presentation format with the .pptx extension. Confirm the format prompt if it appears.

Microsoft PowerPoint for Windows or macOS can also convert the file. Open it through File → Open, choose File → Save As, and select PowerPoint Presentation (.pptx) as the file type.

Quality and compatibility

Check the converted slides in the target program. Fonts, animations, transitions, embedded media, and effects from an older presentation may render differently or require adjustment. Keep the original PPS if you need to compare the result with the source.
