# HarfBuzz Manual

HarfBuzz

HarfBuzz is a text shaping library. Using the HarfBuzz library allows programs to convert a sequence of Unicode input into properly formatted and positioned glyph output—for any writing system and language. HarfBuzz also includes font subsetting, glyph rasterization (bitmap, vector, and GPU), and integration with FreeType, Cairo, CoreText, DirectWrite, and other platforms.

See github.com/harfbuzz/harfbuzz for an overview of all libraries and tools, download instructions, and development resources.
