Pixel fonts, also known as bitmap fonts or raster fonts, are a type of digital typography that uses small squares called pixels to form the individual characters and symbols. These fonts are designed for low-resolution displays and are optimized for readability at small sizes, typically on computer screens, retro video games, and early digital devices. Each character in a pixel font is composed of a grid of pixels, which gives it a distinctive blocky, pixelated appearance. Due to their simplicity and nostalgia factor, pixel fonts have maintained popularity among designers and developers, often being used in pixel art, 8-bit and 16-bit video games, as well as for creating a retro aesthetic in modern design projects.
