• Why convert? To use web fonts in offline tools or ensure compatibility with software that doesn't support WOFF2.

Conversion Methods:

1. Online Tools: Platforms like ConvertHub make the process quick and simple - upload, convert, and download your TTF file.
2. Python with FontTools: For more control, use Python scripts to convert files locally, especially for batch processing.

After conversion, test the TTF file in applications to ensure proper rendering and kerning. Always keep your original WOFF2 file as a backup. Whether you prefer online tools or coding solutions, converting WOFF2 to TTF is straightforward and ensures your fonts are ready for any project.

How to Convert a woff2 Font to ttf Using Python and FontTools

Preparing Your File for Conversion

Before diving into the conversion process, it's important to ensure your WOFF2 file is valid and decide which method of conversion works best for you. Taking these steps ahead of time can save you from unnecessary errors and wasted effort.

Check Your File

Start by verifying your WOFF2 file. Look for the header signature 0x774F4632 (or "wOF2"), as outlined by the W3C Web Fonts Working Group. You can use their WOFF2 validator, available on GitHub, to confirm the file's structure.

Keep in mind that ConvertHub allows free users to upload files up to 100MB, while premium accounts can handle files as large as 2GB. Make sure your file doesn't include any unwanted data between blocks - files with such issues will be rejected by compliant decoders.

If you're converting a file from a URL, check that the server provides the correct MIME type (like font/woff2 or application/font-woff2) and that the file is accessible via HTTPS. For local files, ensure the file path is accurate and you have the necessary permissions to write to the output directory. These verification steps are essential for avoiding hiccups during the conversion process.

Choose Your Conversion Method

Once your file checks out, it's time to decide how to convert it. You have two main options: using an online tool or a local script.

Online tools, such as ConvertHub, are user-friendly and efficient. They allow you to drag and drop files and even handle batch processing automatically. If you're converting multiple fonts, the platform typically returns the results as a neatly packaged ZIP archive, making file management easier.

For those who prefer more control, using Python with FontTools is a great option. This approach is particularly useful for batch conversions and custom processing. To streamline the process, place all your WOFF2 files in a single folder. Be sure to wrap file names containing spaces in double quotes (e.g., "$file") to avoid syntax errors. Choose the method that aligns best with your workflow and technical comfort level.

Converting with Python and FontTools

Install Python and FontTools

If you're looking for offline or automated font file conversions, Python and FontTools are great tools to use. First, ensure you have Python 3.9 or later installed. You can check your version by running:

python --version

Next, install FontTools with WOFF2 support by running this command:

pip install fonttools[woff]

This installation includes all necessary dependencies, like the Brotli compression library, which is essential for working with WOFF2 files.

Here’s a quick reference for installation commands:

Target	Command
Standard FontTools	pip install fonttools
FontTools with WOFF2 Support	pip install fonttools[woff]
Brotli Dependency Only	pip install brotli

Once installed, you’re ready to proceed with the conversion process.

Run the Conversion Script

With FontTools set up, you can use Python to convert WOFF2 files to TTF. The fontTools.ttLib.woff2 module simplifies the decompression process. Here’s an example script:

from fontTools.ttLib import woff2

def convert_woff2_to_ttf(input_path, output_path):
    with open(input_path, 'rb') as infile:
        with open(output_path, 'wb') as outfile:
            woff2.decompress(infile, outfile)

convert_woff2_to_ttf('font.woff2', 'font.ttf')

For quick, one-off conversions, you can use this single-line command:

python -c "from fontTools.ttLib import woff2; woff2.decompress('font.woff2', 'font.ttf')"

This approach is perfect for converting a single file without writing a full script.

If you encounter any errors related to Brotli, ensure it’s installed by running:

pip install brotli

Note for Windows users: When specifying file paths, use forward slashes (/) instead of backslashes (\) to avoid issues with escape characters in strings.

Checking Your Converted TTF File

Test in Font Viewers and Applications

Once you've converted your file, it's time to ensure that the TTF version maintains the design's integrity. Start by using online font viewers like FontVS or Jumpshare to preview the file. These tools let you inspect individual glyphs, kerning pairs, and custom text directly in your browser.

Run tests on both Windows and macOS systems to see how the font performs. On Windows, where TrueType hinting plays a bigger role in readability, open your TTF file in apps like Microsoft Word or Chrome to check its appearance at different sizes. On macOS, use Font Book to inspect the file. Navigate to View > Show Font Info and confirm that the "Kind" field lists it as "OpenType TrueType".

Make sure to evaluate OpenType features such as ligatures and variable font axes. If your original WOFF2 file included these features, double-check that they carried over during the conversion process. Additionally, confirm that font families like Regular, Bold, and Italic are grouped correctly in applications. If only the Regular version is installed, some software might try to simulate other styles by slanting or stroking the font, which can compromise quality.

If any issues arise during these tests, there are steps you can take to resolve them.

Fix Common Issues

Start with the basics: clear your font caches, uninstall older versions, restart your software, and reinstall the updated TTF file. This often resolves rendering problems.

For icon fonts, check that glyphs remain properly centered. Misalignment can happen if horizontal offsets reset to zero during conversion. If you're working with variable fonts, avoid generic online converters, as they may disrupt interpolation axes. Instead, rely on command-line tools like Google's woff2_decompress utility to ensure everything functions as expected.

In Microsoft Office, you might need to manually enable kerning. By default, Word applies kerning only to text sized 8pt or larger on Windows, and 5pt or larger on Mac. Adjust these settings in the advanced font options if necessary to improve text spacing.

Conclusion

Key Points

Converting WOFF2 to TTF is a straightforward process. Platforms like ConvertHub offer a free and easy way to handle files up to 100MB in size.
