# Embed Fonts in PDF Documents with C# - A Complete Guide
2+
3+
The Syncfusion .NET PDF Library offers powerful capabilities for embedding fonts in PDF documents, ensuring consistent rendering across devices and platforms. This guide presents a collection of samples that demonstrate how to embed various font types, render complex scripts, optimize file size, and apply font embedding in real-world scenarios.
4+
5+
Sample name | Description
6+
------|------
7+
[Embedding Standard Fonts in PDF](https://github.com/SyncfusionExamples/embed-font-in-pdf-csharp/tree/master/create-pdf-with-standard-font) | Demonstrates how to use built-in standard fonts (like Helvetica, Times New Roman, Courier) in PDF documents. These fonts are widely supported and do not require external font files, making them ideal for basic text rendering.
8+
[Embed a TrueType Font in a PDF Document](https://github.com/SyncfusionExamples/embed-font-in-pdf-csharp/tree/master/embed-truetype-font-in-pdf) | Shows how to embed a TrueType (.ttf) font into a PDF using C#. This ensures that the document retains its intended appearance even if the font is not installed on the viewer’s system.
9+
[Embed OpenType Fonts (OTF) in a PDF Document](https://github.com/SyncfusionExamples/embed-font-in-pdf-csharp/tree/master/embed-otf-font-in-pdf) | Explains how to embed OpenType (.otf) fonts, which support advanced typographic features. This is useful for professional publishing and multilingual documents.
10+
[Rendering Unicode Text in PDF](https://github.com/SyncfusionExamples/embed-font-in-pdf-csharp/tree/master/unicode-multilinqual-text-in-pdf) | Demonstrates how to render Unicode text (e.g., multilingual content) in a PDF by embedding appropriate fonts. This ensures accurate representation of characters from various languages and scripts.
11+
[Rendering Complex Script Text in PDF](https://github.com/SyncfusionExamples/embed-font-in-pdf-csharp/tree/master/complex-script-text-in-pdf) | Shows how to embed fonts that support complex scripts such as Arabic, Hindi, Tamil, or Thai. These scripts require advanced shaping and positioning, which is handled by the embedded font.
12+
[Subsetting Fonts for Optimized File Size](https://github.com/SyncfusionExamples/embed-font-in-pdf-csharp/tree/master/subsetting-fonts-in-pdf) | Illustrates how to subset fonts—embedding only the glyphs used in the document—to reduce the PDF file size while maintaining visual fidelity.
13+
[Embed Fonts in an Existing PDF via PDF/A Conversion](https://github.com/SyncfusionExamples/embed-font-in-pdf-csharp/tree/master/embed-font-in-existing-pdf) | Explains how to embed fonts in an existing PDF document by converting it to PDF/A format, which is designed for long-term archiving and requires all fonts to be embedded.
14+
[Real-World Use Cases](https://github.com/SyncfusionExamples/embed-font-in-pdf-csharp/tree/master/real-world-use-cases) | Highlights practical applications of font embedding:<br>• **Invoice Creator**: Ensures consistent branding and layout across invoices.<br>• **Certificate Generator**: Embeds decorative or signature fonts to maintain design integrity when shared or printed.
