TTF to CFF conversion is the process of transforming a TrueType Font (TTF) file, which uses quadratic Bézier curves and glyph instructions, into a Compact Font Format (CFF) file that stores outlines as cubic Bézier curves in a compact, PostScript-flavored format. This conversion repackages font glyph data and tables to the CFF structure, often producing smaller files and improved compatibility with PostScript and PDF workflows.

Drag your .TTF file from your computer or use the browse function.
Confirm .cff as the selected destination format.
Click "Convert" and download your converted .CFF file once ready.
TTF files use the MIME type 'font/ttf' and are commonly used for on-screen font rendering across operating systems. CFF files have the MIME type 'application/octet-stream' or can be embedded within PDF and PostScript files for printing. Both formats use different codecs for glyph storage, with CFF focusing on compact and efficient outline data for high-quality printing.
The CFF (.CFF) 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, CFF files generally serve the purpose of storing other effectively within their domain.
Convert your TTF font files to CFF format quickly and efficiently using our online TTF to CFF converter. Designed for simplicity and speed, our tool allows designers, developers, and typographers to switch formats without hassle or software installation.
TTF (TrueType Font) is widely supported and ideal for screen display, while CFF (Compact Font Format) is optimized for print quality and PostScript workflows. CFF fonts typically offer more efficient file compression and better curve representation compared to TTF files. Choosing between them depends on your specific design needs and output requirements.
Keep individual TTF files under 50–100 MB for fastest, reliable online conversion; larger files may need desktop tools.
To preserve visual fidelity, retain hinting and do not apply aggressive curve simplification—test in your target renderer (PDF/PostScript) after conversion.
Use subsetting to reduce size when you only need specific glyphs (e.g., Latin only or icon sets) which is ideal for web fonts.
For batch conversions, process files in groups and monitor memory usage; large batches can be automated via command-line tools like fonttools.

Note format limitation: TrueType-specific bytecode hinting may not translate perfectly to CFF’s PostScript-centric hinting, so minor rendering differences can occur on some platforms.
