If you are a designer, engineer, or writer generating PDFs and your clients are complaining about the CIDFont F1Normal error, the issue stems from your export settings.
: When a PDF is exported incorrectly, the software may fail to embed the original font names. It then assigns generic labels like F1 , F2 , or F3 to those missing fonts.
Have you ever opened a PDF document only to be greeted by a frustrating pop-up stating that the font is missing? Alternatively, you might see a blank page, or a document filled with unreadable, garbled characters.
Because CIDFont+F1 is a mapping issue rather than a missing font file, . Instead, you need to fix how the PDF is being read or re-exported. Here are the best ways to fix the problem: 1. Re-export the PDF (The Best Workaround)
| Problem | Likely cause | Free fix | |---------|--------------|-----------| | “CIDFont F1Normal not found” | Missing Asian font | Install (see above) | | Text shows as boxes | Wrong encoding or missing fallback | Use FontForge (free) to change font references in PDF | | Only want a small PDF to work | Embedded subset font broken | Use Google’s pdf-font-remover or Ghostscript to re-generate PDF with new fonts | | “Not a valid CIDFont” | You downloaded a TTF (not OTF/CID) | Get OTF version from official Noto release |
If you're looking for a free and reliable alternative to CIDFont F1Normal, consider exploring open-source font projects or font repositories that offer CJK fonts. These sources often provide high-quality fonts with clear licensing terms, ensuring you can use them safely and compliantly.

Since you want , here’s what to do:
In the PostScript font system, "CID" stands for Character IDentifier, a numeric indexing system typically used for large character sets like those required for East Asian languages. When a PDF is created but the original fonts are not properly embedded, the rendering software may label the missing fonts with generic names like "CIDFont+F1," "CIDFont+F2," and so on. These placeholders are essentially the PDF reader's way of saying: "I know text should be here, but I cannot find the font that created it."
Go to File > Options > Save . Check the box that says Embed fonts in the file .
