How to convert ppsm to ppsx file

A recipient’s presentation viewer or workplace policy may reject a macro-enabled PPSM slideshow. Saving it as PPSX creates a macro-free show file, but removes its VBA macros and any actions that depend on them.
What the PPSM format is
.ppsm is the PowerPoint Macro-Enabled Show format, an Open XML presentation used by people who distribute slideshows containing VBA automation. It opens as a show and can include macros that automate presentation tasks.
What the PPSX format is
.ppsx is the PowerPoint Show format, also based on Open XML. Compatible presentation software opens it directly as a slideshow. It does not support embedded VBA macros, which can make it acceptable to recipients whose software or security rules block macro-enabled files.
Convert online on 101convert.com
- Open the PPSM-to-PPSX converter on this page and upload the file. Multiple files can be converted in one batch; the page shows the per-file size limit.
- Start the conversion. It runs on the server with LibreOffice.
- Download the converted PPSX file.
Convert offline with desktop software
LibreOffice Impress is a free, open-source option for Windows, macOS, and Linux. Open the PPSM file, choose File → Save As, select PowerPoint 2007–365 (.ppsx) in the file-type list, and save.
Microsoft PowerPoint for Windows or macOS can also open and save PPSM files. Open the file, choose File → Save As (or File → Save a Copy in some versions), select PowerPoint Show (*.ppsx) as the file type, and save. Confirm any warning about removing macros only if the presentation no longer needs them.
Compatibility and conversion limits
Saving as PPSX removes the VBA project; buttons, scripts, and other features that rely on those macros will stop working. Slide content and transitions are generally retained, but fonts, embedded media, and application-specific features may display differently. Check the converted file in the presentation software the recipient will use.
