How to Edit a PowerPoint Template

A PowerPoint template is a starting point, not a finished deck — and most of the frustration people have with templates comes from editing slide by slide when the real controls are one menu away. This covers opening a template, applying one to a deck you've already built, changing colors and fonts in one place, and saving your own.

Step 1

Open the template the right way.

A template file ends in .potx. Double-click it and PowerPoint doesn’t open the template — it opens a new, untitled presentation built fromthe template. The title bar will say something like “Presentation1.” That’s correct. The .potx stays clean, and you save your work as a normal .pptx.

If you want to edit the template itself — to change what every future deck starts with — right-click the .potx and choose Open (Windows) or open it from inside PowerPoint with File › Open. Save it back as a .potx when you’re done.

Where PowerPoint keeps templates

On Windows, personal templates live in Documents › Custom Office Templates. You can see or change that folder at File › Options › Save › Default personal templates location. On a Mac it’s ~/Library/Group Containers/UBF8T346G9.Office/User Content/Templates. Anything in those folders shows up under File › New › Personal (Windows) or File › New from Template(Mac). A downloaded .potx sitting in your Downloads folder works fine too — it just won’t appear in that gallery until you move it.

Step 2

Apply a template to a deck you already have.

You don’t have to rebuild a presentation to change its look. Open your existing deck, go to the Design tab, and open the full Themes gallery — the small arrow at the corner of the theme strip. At the bottom, choose Browse for Themes…and point it at the .potx. PowerPoint reapplies the template’s colors, fonts, backgrounds, and layouts to every slide you have.

Expect a little cleanup. Each of your slides uses a named layout (Title Slide, Two Content, and so on), and if the template names its layouts differently PowerPoint makes a best guess. Right-click any slide that looks off, choose Layout, and pick the right one from the new template’s list. That fixes nearly all of it.

Step 3

Change colors and fonts in one place.

This is the step most people skip, and it’s the whole point of a template. Go to View › Slide Master. The large thumbnail at the top of the left pane is the master; the smaller ones under it are the layouts. Change the accent color, the background, or the fonts on the master and every layout — and every slide that uses those layouts — inherits the change.

Two things worth knowing. Colors and Fonts in the Slide Master ribbon set the whole theme at once, which is faster than recoloring shapes. And anything you place on the master (a logo, a footer line) appears on every slide at a fixed position, which is how the templates here keep their graphics out of your content area.

Close Master View when you’re done. If a single slide refuses to pick up the change, it usually has a manual override — select the element and use Reset on the Home tab to send it back to the layout.

Step 4

Save your own template.

Once a deck looks the way you want, strip the content down to sample slides and go to File › Save As. Choose PowerPoint Template (*.potx) as the file type. PowerPoint switches the save location to your personal templates folder automatically, so it appears in the gallery next time.

A good template carries layouts and a few example slides — not last quarter’s numbers. Every template on this site ships eight or ten sample slides for exactly that reason: enough to show how each layout is meant to be used, nothing you’ll have to delete. Start from one of the free PowerPoint templates and save your customized version as your own .potx.

Questions

PowerPoint template questions, answered.

What's the difference between a .potx and a .pptx?

A .pptx is a presentation. A .potx is a template — double-clicking it opens a new, untitled presentation built from the design and leaves the template file untouched, so you can reuse it indefinitely. If you open a .potx and the title bar says "Presentation1," that's working as intended.

Where does PowerPoint store templates?

On Windows, personal templates live in Documents › Custom Office Templates by default; File › Options › Save › "Default personal templates location" shows or changes the folder. On a Mac, they're in ~/Library/Group Containers/UBF8T346G9.Office/User Content/Templates. Anything saved there shows up under File › New › Personal (Windows) or File › New from Template (Mac).

How do I apply a template to a presentation I've already made?

Open your existing deck, go to the Design tab, open the Themes gallery (the small arrow in the corner of the theme strip), and choose Browse for Themes. Point it at the .potx and PowerPoint reapplies the colors, fonts, and layouts to your slides. Expect some cleanup where your slide count or layout names differ from the template's.

How do I change the colors or fonts everywhere at once?

View › Slide Master. The top thumbnail is the master; change the accent color, background, or font there and every layout underneath inherits it. Close Master View when you're done. Editing on the master is what makes a deck feel designed instead of decorated slide by slide.

Can I turn my finished deck into a template?

Yes. File › Save As, then choose "PowerPoint Template (*.potx)" as the file type. PowerPoint saves it to your personal templates folder automatically. Strip the content first — a template should carry layouts and sample slides, not last quarter's numbers.

The template opened but my old slides look wrong — why?

Each slide uses a named layout (Title, Two Content, and so on). When the new template's layouts don't match your old ones, PowerPoint does its best guess. Right-click a slide › Layout and pick the right one from the new template's list; that resolves most of it.

Will these templates work in older PowerPoint, Microsoft 365, and Keynote?

The .potx format opens in PowerPoint 2010 and later, Microsoft 365 on Windows and Mac, and PowerPoint for the web (which can open templates but not save new ones). Keynote imports .potx too, with occasional font substitution.
