Convert OTF to RAW

Understanding OTF and RAW file formats

OTF (OpenType Font) is a widely used font file format developed by Microsoft and Adobe. It supports advanced typographic features and is compatible with most modern operating systems and design software. RAW is a generic term for unprocessed data files, most commonly associated with digital camera images, but it can also refer to any binary or text data that hasn't been formatted for a specific application.

Why convert OTF to RAW?

Converting an OTF font to a RAW file is an uncommon process, typically done for specialized purposes such as font analysis, reverse engineering, or embedding font data into custom applications. The RAW file in this context would contain the binary data of the OTF file, not a usable font format for design or word processing.

How to convert OTF to RAW

Since OTF to RAW conversion is essentially extracting the binary data from the font file, the process is straightforward. You can simply rename the file extension from .otf to .raw, or use a hex editor to export the binary content. However, if you need to manipulate or analyze the font data, specialized tools are recommended.

Recommended software for OTF to RAW conversion

• HxD Hex Editor (Windows): Open the OTF file, then use File → Save As and change the extension to .raw.
• Hex Fiend (macOS): Open the OTF file, then use File → Save As and specify the .raw extension.
• FontForge: For advanced users, FontForge can open OTF files and export font data, though not directly as RAW, but you can extract tables or binary data for further processing.

Step-by-step conversion using HxD Hex Editor

1. Download and install HxD Hex Editor.
2. Open your OTF file in HxD.
3. Go to File → Save As.
4. Change the file extension from .otf to .raw.
5. Click Save. You now have a RAW file containing the binary data of your OTF font.

Important considerations

• The resulting RAW file is not a font file and cannot be used as a font in design or word processing software.
• This conversion is mainly for developers or analysts who need access to the raw binary data of a font.
• Always keep a backup of your original OTF file before conversion.
