When application performance is a must, D-Type fonts earn your trust.
If you are using D-Type Font Engine or D-Type PowerDoc Engine to render text, it makes sense to store your fonts in D-Type format. D-Type fonts are more versatile and more compact than existing commonly used font formats, such as TypeType, OpenType, Type 1 and even Adobe’s CFF (Compact Font Format). D-Type fonts can also provide an extra performance boost for your applications. Converting any existing scalable font format to D-Type format is straightforward when using D-Type Font Converter.
D-Type Font Converter is provided at no cost when you purchase a license for one of the following D-Type libraries:
D-Type font format is feature-rich. Every feature available in existing scalable font formats is also present in D-Type. However, the D-Type font format is more compact and more versatile than other font formats, making it an ideal choice for D-Type Font Engine.

In the following section, we demonstrate the compactness and efficiency of the D-Type font format. We compare the sizes of eight randomly selected fonts in TrueType, Type 1, and CFF (Compact Font Format) with D-Type. We also show the size of each font when compressed using a conventional ZIP compressor, illustrating the efficiency of each format. For example, if a 90 KB font file can be compressed to a 46 KB ZIP file, its efficiency is only about 51% (calculated as 100 * 46 / 90), which is not very high. Conversely, if a 90 KB font file can be compressed to an 85 KB ZIP file, its efficiency is approximately 94% (calculated as 100 * 85 / 90), indicating a high level of compactness. When efficiency is this high, little additional size reduction can be achieved through compression, meaning the font file is already highly compact. The tests we conducted show that fonts converted from TrueType/OpenType, Type 1, and CFF formats to D-Type are consistently extremely compact, with an average efficiency around 90%.
It is also noteworthy that the efficiency of TrueType/OpenType, likely the most commonly used format today, is relatively low, around 58%. More importantly, converting TrueType/OpenType fonts to D-Type can reduce their file size by nearly three times!
: It provides a structured approach to analyzing market problems, which is essential for identifying the "strategic misfits" mentioned in his other works. Summary of Impact
Business development (BD) has evolved from a peripheral “sales‑support” function into a strategic engine that drives growth, creates value, and sustains competitive advantage. In the digital age—where market dynamics shift in weeks rather than years—organizations need a disciplined, data‑driven, and relationship‑focused BD approach.

The efficiency of the Type 1 format is consistently high, averaging around 96%. In most cases, the original file size is very close to the compressed size. However, Type 1 fonts are limited to a maximum of 256 glyphs.
The efficiency of the D-Type format is also very high and consistent, averaging around 91% (about 5% less than Type 1). More importantly, D-Type fonts are not restricted to 256 glyphs.
On average, D-Type fonts are more than twice as small as their corresponding Type 1 files.

The efficiency of the CFF format varies significantly, ranging from as low as 46% to as high as 88%.
The efficiency of the D-Type format remains consistently high, averaging around 90%. In some extreme cases, it approaches 97%, indicating that further size reduction using conventional ZIP compressors is generally not feasible.
On average, D-Type fonts are more than 1.3 times smaller than their corresponding CFF files.
