TTF to UFO conversion is the process of transforming a TrueType Font (TTF) binary font file into a Unified Font Object (UFO) — an XML-based, human- and tool-friendly source format used by type designers. This conversion extracts glyph outlines, metrics, and font metadata from the compiled TTF and maps them into the editable UFO structure for further design, version control, or tooling workflows.

Drag your .TTF file from your computer or use the browse function.
Confirm .ufo as the selected destination format.
Click "Convert" and download your converted .UFO file once ready.
TTF files typically use the MIME type 'font/ttf' and are supported across most operating systems for font rendering. UFO files have the MIME type 'application/x-fontsource' and consist of a directory with XML and glyph data for detailed font editing. Conversion involves parsing TTF outlines and metadata to generate a structured UFO source folder compatible with font design tools.
The UFO (.UFO) format is commonly used for other. Understanding its characteristics can be helpful when converting to or from other formats like TTF.
While specific technical details aren't available here, UFO files generally serve the purpose of storing other effectively within their domain.
Our Online TTF to UFO Converter allows you to seamlessly convert TrueType Font (TTF) files into Unified Font Object (UFO) format directly in your browser. Designed for font designers and developers, this tool offers a straightforward solution to transform your font files without the need for complex software.
TTF is a widely used font format primarily designed for display and printing, with limited support for complex glyph data. UFO, on the other hand, is an open-source, XML-based format intended for detailed font design and collaborative workflows. While TTF is optimized for end-user font rendering, UFO serves as an editable source format favored by type designers.
Keep source TTF files under 50–200 MB for best responsiveness; very large fonts with thousands of glyphs can slow conversion and editing tools.
To preserve design fidelity, enable float coordinate export and include glyph components and composite glyph decomposition when available.
If converting variable fonts, decide whether you need separate UFO masters for each instance or a single master; some converters cannot preserve variable data and will flatten to static outlines.
For batch conversion, group fonts by family and weight to avoid name collisions; test one file first to confirm settings before processing many.

Note format limitation: TTF hinting (TrueType bytecode) and advanced OpenType layout tables (GSUB/GPOS) may not fully round-trip into UFO — these often require manual rework or separate storage.
