If you use non-standard fonts in your project your PDF document will normally only be displayed correctly on the user's computer if the fonts are also installed there. You can solve this problem by embedding the fonts in your PDF document, but this can increase the size of your document considerably, particularly if you are using Unicode-based languages like Asian languages.

If you need to keep your PDF files as small as possible it is advisable to only use standard fonts like Arial and Times Roman that will be installed on all users' computers. You can then reduce the PDF file size by adding these fonts to the exclusion list (see below).

Options:

Embedding True Type fonts:

If you must embed fonts you can reduce the size of your PDF files by selecting the right embedding option.

Embed TrueType fonts embeds all TrueType fonts except the fonts you add to the exclusion list (see below).

Embed symbol fonts only embeds fonts like Symbol and Wingdings. This ensures that special characters that depend on these fonts will be displayed correctly. Other fonts not found on the user's computers will be substituted with available similar fonts.

Use Base 14 Type1 fonts tells Acrobat to substitute its own built-in fonts. This switches off font embedding and will work adequately if your fonts are similar enough to the Base 14 fonts (Times/Mac or Times New Roman PS MT /Win; Helvetica/Mac or Arial MT/Win; Courier, Symbol, and Zapf Dingbats, each with regular, bold, italic or oblique, and bold italic styles).

Embed TrueType subset only embeds the code pages of the TrueType fonts that are actually used in your project.

Embed TrueType subset (used characters only) saves even more space by only embedding the characters that are actually used in your project. Note that this can slow down compiling considerably with larger projects.

Do not embed these fonts:

If you choose Embed TrueType fonts you can reduce the size of your output file by excluding all the common fonts that all users are likely to have installed on their computers.

All the fonts you add to this list will not be embedded in your output file.

CID Font Mode:

The CID Font Mode option in Configuration > Publishing Options > Adobe PDF > Font Embedding can reduce the size of your PDF for projects written in Unicode-based languages, particularly Asian languages. In addition to this it also improves the correct rendering of special Unicode characters in PDF.

When you set CID Font Mode to Unicode only the characters actually used in the font are embedded in the PDF file, in a special internal format.

This works correctly with most Asian languages. However, it may sometimes cause problems with western languages like Russian or other European languages with special characters.

See CID mode for Unicode fonts for more details.
