The choices you make here can have a significant impact on the overall file size, which is why it’s essential to understand how they work and how to make the most out of your PDF.
Embedded Fonts vs. System Fonts
In PDFs, fonts can either be embedded or linked to system fonts. When a font is embedded, it means that the font data is included directly within the PDF file. This has both positive and negative effects on file size. On the one hand, using embedded fonts ensures that the document will look exactly as intended, regardless of the system or device it’s being viewed on. On the other hand, the extra data required to store the font can increase the file size, making it less efficient.
Font Substitution
To mitigate the effects of large fonts on file size, designers often use font substitution techniques. This involves replacing fonts with less data-intensive alternatives or using font styles (like bold or italic) that are already available on the system. For example, if a document uses a font that’s not installed on the system, the PDF reader might substitute it with a similar font from the system’s font library. This not only saves on file size but also makes the document more accessible on a wider range of devices.
Choosing Fonts and Typography Settings
