About FON files
The .FON file is a legacy Windows bitmap font resource natively utilized by older versions of the Microsoft Windows operating system. Structurally, many .FON files are actually older 16-bit executable (.EXE) files or dynamic link libraries that act as resource containers holding rasterized font glyphs. They were primarily designed for system dialogs, the command prompt, and DOS-era applications. Users traditionally preview these files using the built-in Windows Font Viewer. Because .FON files are bitmap-based, they suffer from severe limitations in modern workflows. They do not scale smoothly, resulting in heavily pixelated text when enlarged. Furthermore, modern web browsers, contemporary operating systems like macOS, and graphic design tools such as Adobe Illustrator generally refuse to load them. This forces users to convert .FON to modern vector equivalents like .TTF (TrueType) or .OTF (OpenType) for broad system compatibility, or .WOFF for web integration. However, this file format is difficult to open or convert because translating raster pixels into scalable vector curves requires complex optical tracing. Often only the original software or specialized tools like Fontographer can properly read or export the data. Our system can inspect the file, and show text or internal content. If our analysis detects a supported underlying or embedded format, viewing or conversion may still be possible.
Convert.Guru analyzes your FON file, detects the exact format, and lets you read the text inside.
If you want to convert FON file to TTF, OTF, WOFF, WOFF2, EOT, SVG, BDF, PCF, FNT, PFM, AFM or PFB, you can use Windows Font Viewer or similar software from the "Legacy Font Storage" category. In the File menu, look for Save As… or Export….
To convert UFO, WOFF, PFB, GXF, AFM, F3F, SFD, WOFF2, PSF, TTF, TXF or OTF files to FON, try Windows Font Viewer or another comparable tool in the "Legacy Font Storage" category.
The FON Converter Story
The history of Convert.Guru began over 25 years ago in California with Tom Simondi’s file-format database. A former contributor to Space Shuttle development and a software pioneer of the 1980s, Simondi established a trusted resource for file type analysis that was even referenced by Microsoft Windows XP. Today, we use modern technology to process and convert thousands of file formats while continually improving our FON converter.
