Techniques pertaining to embedding fonts in a PDF document are disclosed. A processing component executing a PDF application programming interface (API) may be operative to identify each character in a PDF file associated with an un-embedded font. The PDF API may store a bitmap representation for each identified character in the PDF file associated with the un-embedded font. The PDF API may then create a bitmap font character from the bitmap representation for each identified character in the PDF file associated with an un-embedded font and replace each reference to a character in the PDF file associated with an un-embedded font with a reference to its corresponding bitmap font character.
