Here is the guide to the font family (F1–F7), what makes them "better," and where to find the free download.
You open a PDF's properties (via File > Properties > Fonts tab) and see entries like "CIDFont+F1," "F2," "F3," etc. This is the PDF viewer telling you: "I see these fonts are referenced, but I don't have the actual data for them locally."
When a PDF is exported from programs like Microsoft Word or a web browser, the software might fail to embed the actual font data. To ensure the document still renders, the PDF generator assigns these generic names:

This is the most challenging scenario. You have a PDF from a client that uses these "F" placeholders, and you need to edit the text in Illustrator or InDesign.
If you’re handling documents with large character sets or complex typographic requirements, CID fonts offer significant benefits over traditional font formats.
Think of a PDF as a complex instruction manual for a printer or screen. This manual includes a "font list" that tells the system which typeface to use. When a font used to create the PDF is not embedded in the file, and also missing from the system opening it, the PDF renderer (like Acrobat or Illustrator) steps in with a default action. It does not know the original font's name, so it labels the missing resource with a generic, internal tag like "CIDFont+F1" for the first missing font, "CIDFont+F2" for the second, and so on.

If you can view the text but cannot copy or print it, try this: Open the file in a web browser (like Google Chrome). Press Ctrl + P (Windows) or Cmd + P (Mac).
To solve this, Adobe developed the CID-keyed font format. Instead of mapping a character directly to a keyboard stroke, it assigns each character a unique index number (a CID). Why do you see F1 through F7 errors?
Have you ever opened a PDF in Adobe Illustrator or Acrobat, only to find a perplexing alert about missing fonts named "CIDFont+F1" or "CIDFont+F2"? Or perhaps you've glimpsed a stream of generic font tags like /F1 , /F2 , /F3 in a document's properties and wondered what they mean. If you've embarked on a search to hoping to solve the puzzle, you've likely been met with confusion. To ensure the document still renders, the PDF
If the PDF contains Asian languages or unique symbols, Adobe offers free . Installing these packs adds the missing CID font subsets directly to your reader. 3. Print as PDF (The Force-Flatten Method)
To prevent these formatting disasters in your own documents, you should use highly compatible, universally supported open-source fonts.
In this guide, we’ll demystify CID fonts F1 through F7, explain why they appear, and—most importantly—show you where to find to fix missing fonts, improve rendering, and streamline your workflow.
