An OTB file is an OpenType Bitmap Font file. It stores bitmap-based font glyphs (pixel fonts) inside the OpenType font structure. Unlike standard vector fonts, OTB fonts use pre-rendered pixel designs, which makes them ideal for small sizes, retro-style text, and screen-specific typography.
OTB files are mainly used when sharp pixel-perfect text rendering is more important than scalability.
OTB files are commonly used for:
Bitmap and pixel-style fonts
Retro or game-style typography
UI elements requiring exact pixel alignment
Legacy or screen-optimized font rendering
OTB files can be opened or used with:
Font viewers on Windows and macOS
FontForge
Adobe applications (limited support)
Operating system font managers
They are typically installed like regular fonts.
Yes.
OTB uses bitmap glyphs, while OTF and TTF use scalable vector outlines. OTB fonts do not scale well but stay crisp at designed sizes.
