About formats

PS is the standard extension for files written in PostScript, the page description language created by Adobe Systems and first shipped in 1984 with the Apple LaserWriter. A PostScript file is a complete program that describes the precise appearance of a page — text, vector graphics, curves, fills, and even embedded raster images — using a stack-based interpreted language with full programming constructs. When sent to a PostScript-compatible printer or interpreter (such as Ghostscript), the program executes and produces rendered output. PostScript introduced cubic Bezier curves as the standard representation for smooth outlines, a mathematical model that became the foundation for virtually all subsequent vector graphics and font technology including PDF, SVG, and OpenType. The language also serves as a font format: Type 1 PostScript fonts encode glyph outlines as PostScript programs with hinting instructions for sharp rendering at low resolutions, while Type 3 fonts use the full language to define arbitrarily complex glyphs. One advantage is device independence — a PostScript file produces identical output whether rendered on a 300 dpi desktop printer, a high-resolution imagesetter, or a software rasterizer, because it describes shapes mathematically rather than as pixel grids. The human-readable text format provides another practical strength: PS files can be inspected, debugged, and modified with any text editor, and they can be generated programmatically by any software without requiring specialized libraries. PostScript files are widely handled by Ghostscript, Adobe Acrobat, preview applications, and numerous publishing and graphics tools.

CFF (Compact Font Format) is a font outline format developed by Adobe Systems around 1996 as a more efficient successor to the Type 1 font representation. CFF uses Type 2 charstrings — an optimized encoding that supports multiple arguments per operator, default value elision, and shared subroutines — to describe the same cubic Bezier glyph outlines as Type 1 but with substantially less storage. A typical CFF font is 20-50% smaller than its Type 1 equivalent. The format can function as a standalone font file or, more commonly, as the outline data table inside an OpenType font container (the CFF table in OTF files with PostScript outlines). CFF supports multiple fonts within a single file through its FontSet structure, sharing global subroutines across the collection to further reduce size. One advantage is compression efficiency without lossy degradation — every control point and hint is preserved exactly, just encoded more compactly. The format also inherits the full hinting capability of Type 1, including stem hints, counter hints, and alignment zones that ensure crisp rendering on low-resolution screens and printers. CFF2, an evolution introduced with OpenType 1.8, adds support for font variations (variable fonts) by allowing interpolation across multiple design axes. Broad support in PDF viewers, web browsers via OpenType, and professional design software makes CFF one of the most widely deployed outline formats in digital typography.

Frequently Asked Questions

Why convert PS to CFF?

CFF stores PostScript outlines in a compact binary form. Converting PS to CFF produces smaller, more efficient font data for embedding.

What applications support CFF?

CFF data is used inside OpenType fonts and supported by Adobe products, FontForge, and professional typesetting applications.

Does CFF preserve outline quality?

CFF uses the same cubic Bezier curves as PostScript. Glyph outlines transfer without any mathematical conversion or quality loss.

Is the converter free to use?

Convertio offers free PS to CFF conversion for all users. Premium tiers expand limits for professional font production workflows.

How compact is the CFF output?

CFF uses efficient encoding and subroutinization to reduce file size significantly compared to raw PostScript font definitions.

Are my files private?

Convertio encrypts all transfers and deletes uploaded PS files after conversion. CFF outputs are purged within 24 hours.
