# How to apply a PowerPoint template to an existing presentation > To apply a template to an existing presentation, start a new file from the template with File → New, copy your slides and paste them into it with Paste Options → Use Destination Theme. That is the route Microsoft's support page recommends. To change the design inside the same file, open Design → Themes and apply the theme to all slides. Afterwards reapply layouts, check the slide size and fix text that was formatted by hand. - Source: https://ai-presentations.com/guides/apply-template-to-existing-presentation/ - Updated: 21 October 2026 - Language: English - German version: https://ai-presentations.com/de/ratgeber/powerpoint-vorlage-uebernehmen/ You have a finished deck in the wrong design and a template that looks right. **Applying a template to an existing presentation** means moving the slides you already have onto the template's theme, master and layouts without retyping anything. Microsoft's own instructions recommend starting a new file from the template and pasting your slides into it with **Use Destination Theme**. Applying a theme inside the old file with **Design → Themes** is the shorter route when only the look has to change. ## How do I apply a template to an existing presentation? Start from the template, not from the old deck. Microsoft's page on [applying a template to an existing presentation](https://support.microsoft.com/en-us/powerpoint/apply-a-template-to-an-existing-presentation) gives the reason: when you start fresh from the template and import your slides, everything in the file, especially what you create later, takes on the template's look and formatting. **Steps** 1. Save a copy of the old deck so you can compare the two and go back. 2. Create a file from the template. Choose **File → New**, open the tab next to Featured (named Personal, Shared or Custom) or the templates listed under your organization's name, select the template and choose **Create**. If you only have the template as a file, choose **File → Open**, open it, then choose **File → Save As** and set the file format to **PowerPoint Presentation (.pptx)**. 3. Open the old deck. In the thumbnail pane, select the slides: **Ctrl+A** for all of them, or hold **Ctrl** and click single slides. Copy them with **Ctrl+C**. 4. Switch to the new file, right-click in the thumbnail pane and, under **Paste Options**, choose **Use Destination Theme**. 5. Delete the template's sample slides that you do not need, then save the file. On a Mac the page uses Command+A, Command+C and Command+V, and the pasted slides take on the template's design. The Paste Options offer three choices, and only one of them applies the template. | Paste option | What it does | Use it for | | ---------------------- | --------------------------------------------------------------------- | -------------------------------------------------------------------- | | Use Destination Theme | Adapts the copied slide to match the theme of the file you paste into | Slides that should take the template's fonts, colors and layouts | | Keep Source Formatting | Keeps the slide's original theme format | Slides that must stay in their old design, such as a partner's slide | | Picture | Inserts an image of the source slide that you can move and resize | A slide that has to look exactly as before and needs no editing | Microsoft describes these options on its pages about [copying and pasting slides](https://support.microsoft.com/en-us/powerpoint/copy-and-paste-your-slides) and [reusing slides](https://support.microsoft.com/en-us/office/reuse-slides-in-powerpoint-for-office-365-4772661f-ced0-446b-bb28-878dfa8c23f1). As of October 2026, the second page says that Reuse Slides is retired starting January 1, 2026 and points to copy and paste, which is why the steps above do not use it. ## Can I apply a theme without copying slides? Yes. Applying the theme inside the old file is the shorter route when you only have a theme, or when only the look should change. A theme is a set of colors, fonts and effects, and Microsoft says every theme includes a master and layouts, so the new design arrives with its own layouts. A template is a theme plus some sample content, so sample slides do not come along. **Steps** 1. Save a copy of the deck, then select a slide in the thumbnail pane. 2. On the **Design** tab, in the **Themes** group, select **Themes** to open the whole gallery. 3. Pick the design. Built-in themes sit under Office, a theme you saved yourself appears under Custom, and **Browse for Themes** locates a custom theme or a themed document stored somewhere else. 4. Choose the scope. Point at the theme, right-click and select **Apply to All Slides**. To restyle only some slides, select them first with **Ctrl** and choose **Apply to Selected Slides** instead. 5. If the result is wrong, press **Alt+Backspace** at once, or repeat the steps with another theme. These steps follow Microsoft's page on [removing or changing the current theme](https://support.microsoft.com/en-US/PowerPoint/remove-or-change-the-current-theme). ## Which route should I choose? The one choice to avoid is restyling slide by slide. > **Avoid: Restyle slide by slide** > > Open each slide and change the font, the colors and the logo by hand. > > Every slide drifts a little, and the next slide someone pastes in brings the old look back. > **Do: Move the deck onto the template** > > Paste the slides into a file from the template, or apply the theme once. > > Fonts, colors, logo and footer come from the master, so the next change is made in one place. | Your situation | Route | Why | | --------------------------------------------------------------------------- | ------------------------------------------------------------ | ----------------------------------------------------------------------------------------------- | | You have a company template, in **File → New** or as a file | Start from the template and paste with Use Destination Theme | Microsoft's recommended route, and the template's layouts and sample slides are in the new file | | You only have a theme, or a presentation that already has the target design | **Design → Themes → Browse for Themes** | A theme carries colors, fonts, effects, master and layouts | | Only part of the deck should change | **Apply to Selected Slides** | The other slides keep their design | | A few slides must keep a partner's or client's look | Paste those slides with Keep Source Formatting | They keep their original theme format | > **Tip: Check what the template contains first** > > Open the template and choose **View → Slide Master** before you paste anything. If it has no layout for a slide type your deck needs, such as two columns or a table slide, add one first. How to do that is covered in the [slide master guide](https://ai-presentations.com/guides/slide-master/). ## What breaks after I apply a template, and how do I fix it? Expect some cleanup. Switch to Slide Sorter view (on the View tab, or with the button at the bottom of the window) to see every slide as a thumbnail, then work through this table. | What you see | Why | Fix | | --------------------------------------------- | ---------------------------------------------------------------- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | | Content looks too small, too large or cropped | The old deck is 4:3 and the template 16:9, or the reverse | **Design → Slide Size** offers Standard (4:3), Widescreen (16:9) and Custom Slide Size. If PowerPoint asks how to scale, Maximize enlarges the content and Ensure Fit shrinks it | | A slide keeps the positions of the old layout | The layout was not reapplied | Select the slides in Normal view, choose **Home → Layout** and pick the layout again, or use **Home → Reset**, which does not delete content you added | | Text keeps its old font or color | Formatting applied by hand does not follow the theme | Select the text, open the font list and pick a theme font at the top; for shapes use **Shape Format → Shape Fill** and a theme color; to swap one font everywhere use **Home → Replace → Replace Fonts** | | Some text ignores the new layout | It sits in a loose text box, not in a placeholder | Cut the text and paste it into the layout's placeholder, or format the box by hand | | Footers or slide numbers disappeared | Footers are off on the layouts or not switched on for the slides | Tick **Footers** in the Master Layout group in Slide Master view, then use **Insert → Header and Footer** | | Pasted slides keep their old design | They were pasted with Keep Source Formatting | Paste again with **Use Destination Theme** | | The template is missing in the gallery | It is stored in another location | **Design → Themes → Browse for Themes** | The fixes follow Microsoft's pages on [changing the size of your slides](https://support.microsoft.com/en-us/powerpoint/change-the-size-of-your-powerpoint-slides), [editing and re-applying a slide layout](https://support.microsoft.com/en-US/PowerPoint/edit-and-re-apply-a-slide-layout), [changing fonts](https://support.microsoft.com/en-us/powerpoint/change-the-fonts-in-a-presentation) and [using multiple themes](https://support.microsoft.com/en-us/powerpoint/use-multiple-themes-in-one-presentation). If the slide size is the problem, the glossary entry on [aspect ratio](https://ai-presentations.com/glossary/aspect-ratio/) explains the choice, and the [slide layout](https://ai-presentations.com/glossary/slide-layout/) entry explains why layouts matter for everything above. ## Where do I find my company's template? Start in **File → New**. Microsoft's page says personal and workgroup templates sit on the tab next to Featured, named Personal, Shared or Custom. Templates that your organization publishes appear under your organization's name, which Microsoft's pages describe as a folder or a tab. On a Mac, use **File → New from template**; in PowerPoint for the web, use **File → New → Browse templates** and select your company name. As of October 2026, Microsoft's page [Use your organization's templates in PowerPoint](https://support.microsoft.com/en-US/PowerPoint/use-your-organization-s-templates-in-powerpoint) says this needs a Microsoft 365 E3 or E5 plan, and that you should contact your IT admin if the template you need is not there. Personal templates live in the location set under **File → Options → Save**; without one, Microsoft suggests a Custom Office Templates folder under Documents. If nobody can tell you where the file is, ask whoever owns your brand, usually communications or marketing. The guide to [building a corporate design template](https://ai-presentations.com/guides/corporate-design-powerpoint-template/) covers what belongs in the file and how to create one when none exists.

The AI can restyle an existing deck when you ask it to. In the library, choose **Open PowerPoint, PDF or Word**: that imports a .pptx of up to 30 MB as a new document and never changes the original. Slide size and speaker notes are kept. How many pages come in depends on the plan: the first 3 on Free, up to 12 on Plus and up to 150 on Pro and Max. The design comes from the Brand page, which stores colors, fonts, a logo and a tone of voice. To apply it to an existing document, open the file and ask, for example “Restyle the whole presentation in our brand”. Your instruction in the request always wins, and because it is an AI request it uses credits. To reuse a finished document as the template for a new one, **Use as template** copies its pages, page format and images into a new document without using credits. Slides the AI builds or restyles follow the design it read from your file: theme fonts and colors, each slide's layout and the footers. More on working from your own design is on the page about [AI presentations in your company template](https://ai-presentations.com/ai-presentation-company-template/), and editing a finished deck is covered under [improving a PowerPoint with AI](https://ai-presentations.com/improve-powerpoint-with-ai/). **Prompt: Restyle a finished deck in your brand** ```text Restyle the whole presentation in our brand: fonts, colors, logo and footer. Keep every text, every number and the slide order exactly as they are, and do not add or remove slides. At the end, list the slides where you changed the layout. ``` The import is a copy, so your original deck stays as it is. Treat the restyled deck as a first version: compare it with the old one slide by slide and check figures, names and line breaks before you send it. **Key takeaways** - Microsoft's recommended route is to start a new file from the template and paste your slides with Use Destination Theme. - To change the design inside the same file, use Design → Themes and Apply to All Slides; Alt+Backspace undoes it at once. - Afterwards reapply layouts with Home → Layout, check Design → Slide Size and fix text that was formatted by hand. - The AI can restyle an imported deck in your brand on request; the result follows the design it read from your file. ## Frequently asked questions ### How do I apply a PowerPoint template to an existing presentation? Start a new file from the template with File, New, then copy your slides from the old deck and paste them into it using Paste Options, Use Destination Theme. Microsoft's support page recommends this route. To restyle inside the same file instead, open Design, Themes, choose Browse for Themes if the theme is stored elsewhere, and apply it to all slides. ### How do I change a PowerPoint template without changing the content? Apply the new design as a theme, or paste the slides into a file from the template with Use Destination Theme. Both change fonts, colors and layouts and leave your text, numbers and pictures in place. Save a copy first, then reapply layouts with Home, Layout and fix anything formatted by hand, because manual formatting does not follow the theme. ### What does Use Destination Theme do in PowerPoint? Use Destination Theme is a Paste Options choice that adapts the copied slide to match the theme of the presentation you paste into. Keep Source Formatting does the opposite and keeps the slide's original theme format, which is why pasted slides sometimes bring their old look with them. ### Why do some slides still look wrong after I apply the template? Usual causes are text or shapes formatted by hand, slides that still follow a layout from the old design, a 4:3 deck on a 16:9 template, and footers that are switched off. Reapply the layout with Home, Layout, use Home, Reset, check Design, Slide Size and tick Footers on the template's layouts. ### Where do I find my company's PowerPoint template? Choose File, New and look for the tab next to Featured named Personal, Shared or Custom, or for the templates listed under your organization's name. As of October 2026 Microsoft says this needs a Microsoft 365 E3 or E5 plan, and that you should contact your IT admin if a template is missing. ### Can AI restyle an existing presentation in my company design? Yes. You can open a PowerPoint file as a new document, leaving the original untouched, and restyle it when you ask, for example “Restyle the whole presentation in our brand”. That is an AI request, so check every slide afterwards. The restyled slides follow the theme fonts and colors, layouts and footers the AI read from your file. ## Related pages - [Slide master in PowerPoint](https://ai-presentations.com/guides/slide-master/): Open, edit and save the slide master in PowerPoint: fonts, colors, logo, layouts, placeholders and footers, with exact menu paths and fixes for common problems. - [Corporate design template](https://ai-presentations.com/guides/corporate-design-powerpoint-template/): Where to find your company's PowerPoint template and how to build a corporate design template with theme colors, fonts, logo and layouts, then share it. - [Copilot with a company template](https://ai-presentations.com/guides/copilot-powerpoint-company-template/): Can Copilot in PowerPoint use your company template?
