Convert a POT template when you need to distribute a finished presentation that opens directly as a slideshow instead of as a reusable design. PPSX is intended for presenting; fill in the template’s slides before converting if the file contains only a blank design.
What the POT format is
POT is Microsoft PowerPoint’s legacy binary template format, associated with PowerPoint 97–2003. It can contain slide layouts, themes, placeholders, and example slides, and is used to create presentations with a consistent design.
What the PPSX format is
PPSX is the Office Open XML PowerPoint Show format. Opening it normally starts the slideshow, while presentation software can still open it for editing. Unlike POT, PPSX is a presentation file, not a reusable template.
Online conversion on 101convert.com
- Open the POT-to-PPSX converter on 101convert.com and upload the POT file. The page displays the per-file size limit.
- Choose PPSX as the output format and start the conversion. The converter runs on the server with LibreOffice and supports batch conversion.
- Download the converted PPSX file or files.
Offline conversion with desktop software
LibreOffice Impress is free and runs on Windows, macOS, and Linux. Open the POT file; if it is a blank template, add the required content and slides. Choose File → Save As, select PowerPoint 2007–365 AutoPlay (.ppsx) as the file type, and save. Confirm the format choice if prompted.
Microsoft PowerPoint for Windows or macOS can also convert the file. Open the POT file; PowerPoint may create a new presentation from the template. Add or edit slides as needed, then choose File → Save As, select PowerPoint Show (*.ppsx), and save.
Quality and compatibility
POT uses an older binary format, while PPSX uses the Office Open XML format. Check fonts, layouts, animations, transitions, and embedded media after conversion, particularly if the source uses older or unsupported features. PPSX does not retain VBA macros; use a macro-enabled PowerPoint Show (.ppsm) if the presentation must preserve VBA functionality.
