How to Change PowerPoint Template for Existing Presentation

1. Open the existing presentation and go to File > Save As
2. Change the file type to “PowerPoint Template (.potx)”
3. Give it a name and save it

Apply New Template

1. Open the presentation you want to apply the new template to
2. Go to Design tab > Themes > Browse for Themes
3. Navigate to and select the new template file
4. Click Apply

The key things to note:

• You cannot remove a theme, only apply a new one
• Applying a new template will change the overall design and formatting
• You may need to manually adjust some formatting after applying the new template
• Make sure any custom fonts are available on other computers, or embed them in the presentation

Some common issues:

• Slide elements shifting position or size when sharing – likely due to missing fonts
• Old formatting remaining – did not properly apply the new template
• Multiple slide masters causing problems – delete unused masters

To ensure consistency, build the presentation using slide layouts from a single slide master. And consider saving important templates in a central slide library for your team.
