You spent time picking the perfect fonts — so it’s frustrating when your PDF replaces them or distorts your layout after you hit save.
This usually happens when fonts aren’t embedded correctly. Without that step, your PDF may not look the same on other devices or apps.
With Smallpdf’s Edit PDF, you can clean up formatting issues fast and make sure your custom fonts display exactly as intended.
In this guide, I’ll show you how to add your fonts properly — no design software or extra steps needed.
Why Embedding Fonts Matters
When fonts aren’t embedded, your PDF may display incorrectly when opened on devices that don’t have those fonts installed. This can ruin the layout, make the text unreadable, and leave a poor impression on your audience.
Embedding fonts:
- Preserves your document's design.
- Ensures readability and consistency.
- Makes your PDF look professional on all devices.
With our easy-to-use tools, you can resolve these issues in minutes.
Steps to Add Custom Fonts to a PDF Using Smallpdf
1. Ensure the Font Is Installed on Your System
The first step is making sure the custom font you want to use is installed on your computer.
- On Windows: Right-click on the font file and select “Install.”
- On macOS: Double-click the font file, then click “Install Font” in the Font Book app.

Additional Tips for Working with Custom Fonts
While embedding fonts is straightforward, here are a few extra tips to ensure your PDFs look their best:
- Check Font Embedding: Open your saved PDF in a viewer that displays font properties (like Adobe Acrobat). Look for terms like “Embedded” or “Embedded Subset” in the font info.
- Avoid Restricted Fonts: Some fonts, particularly free ones, have restrictions on embedding due to licensing. Always check the font license to avoid issues.
- Stick to Standard Fonts for Simplicity: Fonts like Arial, Times New Roman, and Helvetica are widely supported and rarely cause embedding problems.
