In technical terms, "CIDFont+F1", "F2", "F3", and "F4" are not specific brand-name fonts you can download. Instead, they are or internal aliases created by PDF-generating software when a font is embedded or subsetted into a document . 1. What are CIDFonts?

• Form field fonts (AcroForms).
• Vertical writing (CJK vertical text).
• Fallback fonts used when F1 or F2 lack a specific character.

• F1: Usually represents the primary Roman or Standard Latin font (e.g., Times or Helvetica equivalent in the CID space).
• F2: Typically the secondary font or a bold/italic variant.
• F3: Often mapped to a fixed-pitch or monospaced font (like Courier).
• F4: Commonly reserved for a symbolic font or a special character set (like Dingbats or a specific CJK subset).

Pro Tip for Better Performance:

If F1 is embedded as a full font set (20,000+ glyphs) instead of a subset, your PDF will be bloated. Use PDF optimization tools to subset F1 to only the characters used. cid font f1 f2 f3 f4 better
