The "F1" tag (along with F2, F3, etc.) is a assigned by PDF creation software. When a program like Microsoft Word or Adobe InDesign exports a PDF, it may rename the embedded fonts to generic tags like "F1" to maintain a small file size or handle font subsets.
Avoid generic, free online "Print to PDF" extensions. Instead, use reliable PDF engines like Microsoft Word's native "Save As PDF" feature, Adobe Distiller, or trusted virtual printers like CutePDF or Foxit.
Depending on whether you own the original file or just received a broken PDF, choose one of the following solutions. Solution 1: Install the Adobe Font Pack (For Users)
In programs like Adobe Illustrator or InDesign, select your text and use the command (Ctrl+Shift+O / Cmd+Shift+O).
To solve this, Adobe developed the . The core innovation is simple yet powerful: cid font f1 family
Specifies that the CID font characters are mapped vertically.
When a program generates a PDF, it catalogs every font used in the document. To keep the file size minimal and processing speeds fast, the generator assigns internal labels to these fonts: (Font 1) F2 (Font 2) T1 (Type 1 Font)
In the context of PDF internals, fonts are often renamed to avoid conflicts during embedding. When you see a font listed as CIDFont+F1 or a family name of "F1," it typically indicates one of three scenarios:
Key observations:

In this context, is not a brand name or a font style (like Arial or Times). Instead, it is almost always a resource name placeholder used within the PostScript programming language and PDF specifications.
If you have ever opened a PDF document only to be greeted by an error message stating "The font cannot be found" or noticed text appearing as garbled dots and squares, you have encountered the complex world of CID-keyed fonts . Despite sounding like a specific typeface you can simply download, "CIDFont F1" is actually a technical identifier used by PDF generators to handle complex character sets. What is CIDFont F1?
When a PDF is generated, the creator can choose to "embed" the fonts. This packages the font data directly inside the file so it looks identical on any device. If the creator chose not to embed the font—or only embedded a "subset" missing specific characters—your PDF reader will search your local system for the font. If it fails to find it, the text breaks. 2. Conflicting Font Encodings (Identity-H) The "F1" tag (along with F2, F3, etc
The PDF generator expected the user to have the font locally.
When you see /CMap /Identity-H , the F1 family is performing a from the source encoding to Unicode. This is a double-edged sword:
typically refers to the regular weight of the same family. Why Do Errors Occur?
