About formats

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.

PNG (Portable Network Graphics) is a lossless raster image format developed by the PNG Development Group and published as a W3C Recommendation on October 1, 1996, created as a patent-free replacement for GIF after the Unisys LZW patent controversy. PNG uses a two-stage compression pipeline: a prediction filter selects the optimal per-row preprocessing (none, sub, up, average, or Paeth), then DEFLATE compression encodes the filtered data. The format supports rich color modes — 1/2/4/8/16-bit grayscale, 8/16-bit per channel true color, and indexed color with palettes up to 256 entries — all with optional alpha transparency ranging from a single transparent color to a full per-pixel alpha channel with 256 or 65536 levels. PNG also stores gamma correction, ICC color profiles, text metadata, and suggested background color. One advantage is lossless compression with transparency — PNG preserves every pixel exactly while supporting smooth semi-transparent edges, making it the standard format for web graphics, UI elements, logos, screenshots, and any image where artifacts or color shifts are unacceptable. Universal support is another core strength: every web browser, operating system, image editor, and programming library handles PNG natively. The format has proven remarkably durable — after nearly three decades, PNG remains the default lossless web image format. While newer formats like WebP and AVIF offer better compression, PNG's combination of lossless quality, full transparency, and absolute ubiquity keeps it indispensable.

Frequently Asked Questions

Why convert CFF to PNG?

PNG gives you lossless raster output with alpha transparency — ideal for sharing font previews, creating type specimens, or embedding glyphs in design mockups.

How do I open a PNG file?

PNG is universally supported on every OS, browser, and image application. Open it anywhere — from Windows Photos to macOS Preview to any design tool.

Does PNG preserve transparency?

Yes — PNG supports full alpha transparency, so rendered glyphs get smooth anti-aliased edges on a transparent background ready for compositing.

Can I convert multiple CFF files to PNG at once?

Batch conversion is supported. Upload several CFF files simultaneously and each one converts to PNG independently in a single session.

Is this free on Convertio?

Yes — CFF to PNG conversion is completely free. Upload, render, and download without any cost or software installation.
