If you are trying to edit text that currently uses these CID labels, you generally cannot "download" them. Instead, you should:

When you open a PDF document in platforms like Adobe Illustrator or Affinity Designer and encounter errors targeting CIDFont+F1 through F4 , it does not mean a single proprietary font family is missing. Instead, it indicates that the file's original text encoding relies on a Character Identifier (CID) system—often used for large character sets or multi-language files—which your local system cannot map back to its original PostScript or TrueType equivalent.

In Adobe’s and PDF specifications , the suffixes F1, F2, F3, F4 do not refer to standard industry-wide font versions. Instead, they appear in: cid font f1 f2 f3 f4 better

A is a specialized format developed by Adobe to handle complex character sets, primarily used for ideographic languages such as Chinese, Japanese, and Korean (CJK). Unlike simple PostScript fonts that map character codes directly to glyph names, CID fonts utilize a central registry database mapping unique numerical identifiers directly to vector paths.

The labels F1 through F4 are simply an index used by the PDF to distinguish between different fonts or styles used in the same file. While they vary by document, common patterns observed in software exports include:

Screen readers rely on reliable font-to-text mappings. When a document uses nondescript F1, F2, F3, F4 tags without proper /ToUnicode tables, accessibility breaks. A better approach ensures that every CID font carries a reversible mapping to Unicode.
