To ensure the best possible experience for your users, it is important to prepare your PowerPoint content correctly before importing it into Letsignit Slides.
This article outlines the best practices for creating PowerPoint presentations that are easy to use, maintain, and update over time.
Understanding the Structure of a PowerPoint Presentation
To create content that remains easy to manage and update, it helps to understand how a PowerPoint presentation is structured.
A presentation is typically built on three complementary layers: the theme, the template, and the presentation content.
📌 1. The Theme
The theme defines the core visual elements of your brand identity, including:
Your brand colors
The fonts used throughout your presentations
Certain graphic styles and effects
The theme serves as the foundation for all your PowerPoint templates and presentations.
💡 What users see
When the theme is configured correctly, users automatically have access to the correct fonts and colors whenever they create or edit a presentation.
📌 2. The Presentation Template
The template defines the structure of your slides. It is created and configured using the PowerPoint Slide Master.
A template determines:
How content is organized on each slide
Which elements users can edit, such as titles, text, images, and charts
Which elements should remain consistent across all presentations, such as logos, banners, footers, and other brand elements
A well-designed template helps users create presentations more efficiently while ensuring compliance with your brand guidelines.
💡 What users see
Templates appear as slide layouts when users add a new slide in PowerPoint. Each layout provides a predefined structure that is ready to be completed.
📌 3. The Presentation Content
Presentation content includes the materials users work with every day, such as:
Text
Images
Charts
Key figures
Case studies
Customer references
This is typically the type of file imported into Letsignit Slides so it can be reused, customized, and enriched by users.
💡 What users see
Presentations appear in the Letsignit Slides library. Users can insert them into PowerPoint and adapt the content to their specific needs.
Step 1: Configure Your PowerPoint Theme
Before creating your templates, start by defining your company's PowerPoint theme.
The theme contains the core elements of your visual identity, including:
Your brand colors
The fonts used for titles and body content
Graphic styles and effects used throughout your presentations
📌 Define Your Theme Colors
Theme colors help standardize all the colors used across your presentations, including text, backgrounds, hyperlinks, and accent colors.
To create your theme colors:
Open PowerPoint.
Go to the Design tab.
In the Variants group, click Colors > Customize Colors.
Configure the colors that match your brand guidelines.
Save your theme.
📌 Define Your Theme Fonts
Theme fonts automatically apply the correct fonts to titles and content throughout your presentations.
To configure them:
Open the View tab.
Click Slide Master.
In the Slide Master tab, click Fonts > Customize Fonts.
Select a font for headings and another for body text.
Save your changes.
📌 Define Theme Effects
Theme effects control shadows, outlines, fills, and other graphical effects used throughout your presentations.
Open the View tab.
Click Slide Master.
In the Slide Master tab, click Effects.
Select the desired effect set.
📌 Save Your Theme
Once your colors, fonts, and effects have been configured:
Open View > Slide Master.
Click Themes.
Select Save Current Theme.
Save your theme as a
.thmxfile.
You can then reuse this theme across all your PowerPoint templates and presentations.
💡 Menu names may vary depending on your version of PowerPoint. For more information, see Microsoft's documentation: Create your own theme in PowerPoint.
Step 2: Create a Presentation Template
Presentation templates are built using the PowerPoint Slide Master. They define the structure of the slides users will work with, as well as which elements can and cannot be modified.
📌 Create a Layout
A layout defines the structure of a slide, including the placement of titles, content, images, footers, and other elements.
To create a new layout:
Open PowerPoint.
Go to the View tab.
Click Slide Master.
In the Slide Master ribbon, click Insert Layout.
Give the layout a clear name that users will easily recognize.
Add and arrange the desired placeholders and design elements.
💡 The layout name will be visible to users when they insert a new slide in PowerPoint.
📌 Add Editable Placeholders
Placeholders allow users to easily replace or customize slide content.
Use placeholders for any content that should remain editable, including titles, text, images, charts, and tables.
To add a placeholder:
Open Slide Master.
Select the desired layout.
In the Slide Master ribbon, click Insert Placeholder.
Choose the appropriate placeholder type (Text, Picture, Table, Chart, etc.).
Draw the placeholder in the desired location on the slide.
Users will then be able to edit or replace the content within that placeholder.
💡 Tip: Create an Editable Shape
By default, shapes added directly to the Slide Master are locked and cannot be modified by users.
If you want users to customize a shape:
Insert a Text Placeholder.
Select the placeholder.
Open Shape Format.
Click Edit Shape.
Choose the desired shape (rectangle, rounded rectangle, etc.).
This creates an editable shape that users can customize while preserving the formatting defined in your template.
📌 Add Locked Elements
By default, any element added directly to the Slide Master is locked for users.
To add a fixed element:
Open Slide Master.
Select the desired layout.
Insert the elements that should remain consistent across all presentations, such as:
Logos
Banners
Footers
Graphic elements
Position them as needed.
When users work with the presentation, these elements remain visible but cannot be selected, moved, or deleted during normal slide editing.
💡 Good to know
Users can still access the Slide Master and modify the elements it contains. However, these changes only affect their own copy of the presentation and do not impact the original template or presentations used by other users.
💡 For more information, see Microsoft's documentation: Create and save a PowerPoint template.
Step 3: Create a Presentation
Once your theme and template have been created, you can start building presentations.
These files contain the content that users will reuse on a daily basis, such as:
Sales messaging
Key figures
Case studies
Customer references
Corporate presentations
Product catalogs
By default, all content contained in a presentation imported into Letsignit Slides remains editable after insertion into PowerPoint.
Users can:
Edit text
Replace images
Update charts
Remove or add content
Step 4: Save and Optimize Your Presentation
Before importing your presentation or template into Letsignit Slides, take a few minutes to verify your save settings.
📌 Embed Fonts
If your presentation uses custom fonts, we recommend embedding them directly in the PowerPoint file.
To do so:
Click File > Options.
Open the Save section.
Enable Embed fonts in the file.
Save your presentation.
This ensures that your presentation displays correctly even when the required fonts are not installed on the user's device.
💡 Good to know
If fonts are not embedded, PowerPoint may automatically replace them with substitute fonts, which can alter the appearance and layout of your slides.
📌 Optimize File Size
Large files can slow down presentation loading times and make sharing more difficult.
Before importing your presentation, we recommend:
Compressing images
Avoiding unnecessarily large or ultra-high-resolution images
Removing unused slides
Deleting unused images, videos, and other assets
Linking to online videos instead of embedding them whenever possible
💡 Good to know
In most cases, images are the primary cause of large PowerPoint file sizes.
📌 Review Your Presentation Before Importing
Before importing your file into Letsignit Slides, we also recommend that you:
Verify that all images display correctly
Test the different layouts in your template
Check fonts and theme colors
Confirm that locked elements and placeholders behave as expected
Your presentation is now ready to be imported into Letsignit Slides.
Frequently Asked Questions
Do I need to create a PowerPoint template?
Do I need to create a PowerPoint template?
No. You can import a presentation directly into Letsignit Slides without creating a template.
However, templates allow you to provide custom layouts through PowerPoint's New Slide menu. Users can then create new slides based on predefined structures that already comply with your brand guidelines.
If your goal is simply to share existing content—such as a corporate presentation, case study, or product catalog—a standard presentation is usually sufficient.
What is the difference between a presentation and a template?
What is the difference between a presentation and a template?
A presentation contains ready-to-use content, such as corporate slides, case studies, key figures, or product information.
A template, on the other hand, defines the structure of slides and determines which elements users can or cannot modify.
For more information about themes, templates, and presentations, refer to Microsoft's documentation.
What actually increases the size of a PowerPoint presentation?
What actually increases the size of a PowerPoint presentation?
The main contributors are embedded videos and unoptimized images.
For example, a large image used in a slide master can significantly increase the file size, even if it only appears in a small area of the presentation.
To keep presentations lightweight, we recommend compressing images and using visuals that are appropriately sized for their intended display.
Can I modify my theme or template after sharing it?
Can I modify my theme or template after sharing it?
Yes. You can update your themes, templates, and presentations at any time before reimporting them into Letsignit Slides.
Once the updated version has been imported, it must be shared with users so they can benefit from the latest version.
How can I create editable areas?
How can I create editable areas?
There are two approaches, depending on the level of control you need.
Use a standard presentation
In a standard PowerPoint presentation, all content remains editable after insertion into PowerPoint, including:
Text
Images
Charts
Shapes
Tables
This approach is ideal when users need complete flexibility to adapt content.
Use a PowerPoint template
In a template, editable areas are defined using placeholders created in the Slide Master.
Users can modify the content within those placeholders while preserving the structure and formatting defined in the template.
💡 In short: A presentation makes the entire slide editable, while a template allows you to control exactly which areas can be customized.
How can I create locked areas?
How can I create locked areas?
To create locked elements, add them directly to the PowerPoint Slide Master.
This is typically used for:
Logos
Banners
Footers
Brand graphics and visual elements
These elements remain visible on slides but cannot be modified during normal slide editing.
💡 Elements placed in the Slide Master are shared across all slides that use the same layout.
