Free online PPTM to PPTX converter

A recipient’s presentation software may accept PPTX but reject macro-enabled PPTM, or an organization may require macro-free files for distribution. Converting removes the embedded VBA project, so keep the original if its macros are needed.

What the PPTM format is

PPTM is Microsoft PowerPoint’s macro-enabled Open XML presentation format. It is used for presentations that contain VBA macros, such as automated tasks or custom controls, and can include an embedded VBA project.

What the PPTX format is

PPTX is the macro-free Open XML presentation format used by PowerPoint and many other presentation programs. Its broader software support can make it easier to share; unlike PPTM, it cannot store an embedded VBA project.

How to convert

Online on 101convert.com

1. Upload the PPTM file on this page. Multiple files can be converted in one batch; the per-file size limit is shown on the page.
2. Select PPTX as the output format and start the conversion. It runs on the site’s server with LibreOffice.
3. Download the converted PPTX file or files.

Offline with desktop software

LibreOffice Impress is free and runs on Windows, macOS, and Linux. Open the PPTM file, choose File → Save As, select PowerPoint 2007–365 (.pptx) as the file type, and save.

Microsoft PowerPoint for Windows or macOS can also save the presentation as PPTX. Open the file, choose File → Save As, select PowerPoint Presentation (*.pptx), and save. Accept any warning about features that cannot be retained.

Compatibility and limitations

The converted PPTX will not contain the VBA project, so its macros and macro-dependent controls or automation will not work. Check the slides in the target presentation program after conversion; fonts, animations, charts, and embedded media can render differently, particularly when converting with LibreOffice.
