In the world of typography, font formats can be a crucial aspect of design and functionality. With the rise of digital publishing and online design, the need to convert font formats has become more pressing than ever. One such conversion that often poses a challenge is converting OpenType fonts to TrueType. In this article, we will delve into the world of font formats, exploring the differences between OpenType and TrueType, and providing a comprehensive guide on how to convert OpenType fonts to TrueType.
Understanding Font Formats: OpenType and TrueType
Before we dive into the conversion process, it’s essential to understand the basics of font formats and the differences between OpenType and TrueType.
The Evolution of Font Formats
Font formats have undergone significant transformations since the early days of digital typography. The first font format was PostScript, introduced in the 1980s. PostScript was followed by TrueType, which was developed by Apple in the late 1980s. TrueType became a widely adopted format due to its simplicity and compatibility with various operating systems.
Introducing OpenType
In the late 1990s, Adobe and Microsoft collaborated to create OpenType, a more advanced font format that built upon the foundations of TrueType. OpenType offers improved typography capabilities, including support for advanced typographic features, such as ligatures, stylistic sets, and alternate characters. OpenType fonts can contain up to 65,535 glyphs, making them more versatile than TrueType fonts, which are limited to 4,095 glyphs.
Key Differences Between OpenType and TrueType
So, what sets OpenType apart from TrueType? Here are the key differences:
- Glyph Count: OpenType fonts can contain up to 65,535 glyphs, while TrueType fonts are limited to 4,095 glyphs.
- Typographic Features: OpenType fonts support advanced typographic features, such as ligatures, stylistic sets, and alternate characters, which are not available in TrueType fonts.
- Platform Compatibility: OpenType fonts are compatible with both Windows and macOS, while TrueType fonts are more widely supported on Windows.
Why Convert OpenType Fonts to TrueType?
Now that we’ve covered the differences between OpenType and TrueType, let’s explore the scenarios where converting OpenType fonts to TrueType becomes necessary:
Incompatibility Issues
Some older software or systems may not support OpenType fonts, making it essential to convert them to TrueType for compatibility reasons.
File Size Constraints
OpenType fonts can be quite large due to their extensive glyph count and advanced typographic features. Converting them to TrueType can reduce the file size, making them more suitable for web use or other applications where file size is a concern.
Legacy System Support
In some cases, legacy systems or software may only support TrueType fonts. Converting OpenType fonts to TrueType ensures that the font remains usable in these environments.

OpenType and TrueType are both digital font formats used to display text on screens and in print. However, they have some key differences. OpenType is a more modern and versatile format that supports advanced typographic features, such as ligatures, swashes, and alternate characters. TrueType, on the other hand, is an older format that is more limited in its capabilities.
Despite its limitations, TrueType remains a widely supported format, particularly in older software and operating systems. Converting OpenType fonts to TrueType can ensure compatibility and consistency across different platforms and devices. This process can also help to simplify font management and reduce file size.
Why would I want to convert OpenType fonts to TrueType?
There are several reasons why you might want to convert OpenType fonts to TrueType. One reason is to ensure compatibility with older software or operating systems that don’t support OpenType. Additionally, TrueType fonts tend to be smaller in file size, which can be beneficial for web development and digital publishing.
Converting OpenType fonts to TrueType can also be useful for font embedding, where a font is embedded within a document or application. TrueType fonts are often preferred for font embedding because they are more widely supported and can help to avoid copyright and licensing issues. By converting OpenType fonts to TrueType, you can enjoy greater flexibility and freedom in using your fonts.

There are several tools available to convert OpenType fonts to TrueType, both online and offline. One popular offline tool is FontForge, a free and open-source font editor that can be downloaded for Windows, macOS, and Linux. Online tools include FontSquirrel’s Font Converter and Convertio’s Font Converter.
Regardless of which tool you choose, make sure it is reputable and reliable to ensure that your font conversion is accurate and lossless. It’s also a good idea to keep a backup of your original OpenType font files, in case you need to revert to them later.
How do I convert OpenType fonts to TrueType using FontForge?

The conversion process may take a few minutes, depending on the complexity of your font and the speed of your computer. Once the conversion is complete, you can use your new TrueType font file as needed.
Can I convert TrueType fonts back to OpenType?
While it is possible to convert TrueType fonts back to OpenType, the process is not always straightforward or lossless. This is because TrueType fonts may not retain the same level of typographic sophistication as OpenType fonts. Additionally, some font features, such as ligatures and alternate characters, may not be preserved during the conversion process.
That being said, FontForge and other font editors can be used to convert TrueType fonts back to OpenType. However, the results may vary depending on the quality of the original TrueType font file and the conversion tool used. It’s always best to work with the original OpenType font file whenever possible to ensure the highest level of fidelity and quality.
Will converting OpenType fonts to TrueType affect their appearance?
The appearance of your font should not be affected by converting OpenType to TrueType, assuming that the conversion is done correctly and losslessly. However, it’s possible that some font features, such as ligatures or swashes, may not be preserved during the conversion process.
To minimize the risk of visual changes, make sure to use a high-quality font conversion tool and follow the recommended conversion process carefully. It’s also a good idea to compare your original OpenType font file with the converted TrueType font file to ensure that they look identical.
Is converting OpenType fonts to TrueType compatible with all operating systems?
The good news is that TrueType fonts are widely supported across different operating systems, including Windows, macOS, and Linux. This means that once you’ve converted your OpenType font to TrueType, you can use it with confidence across different platforms and devices.
However, it’s worth noting that some older operating systems or software applications may have specific font requirements or limitations. Be sure to test your converted TrueType font file on your target platform to ensure that it displays correctly and doesn’t cause any compatibility issues.
