Begin in the creation workflow
Adobe describes embedding during PDF creation and export, including Acrobat Distiller and InDesign export. Work from the editable source when possible so the same workflow can be repeated after text changes. Installing a font on your own machine does not by itself explain what resources were included in the exported PDF.
Choose full embedding or a subset
Adobe distinguishes embedding an entire font from embedding only the characters used. A subset can reduce file size. Keep the intended output in mind: a viewing copy and an actively edited source document have different resource needs.
Read the PDF font settings
Adobe’s PDF settings documentation describes Embed All Fonts, subset thresholds and Always Embed or Never Embed lists. It also identifies locked entries for fonts with license restrictions. Use the chosen conversion workflow’s documented settings rather than assuming an embedding preference overrides a font supplier’s restriction.
Keep appearance and editing separate
Embedding supports viewing and printing consistency, but it is not a general desktop-font installation package for the recipient. Keep the editable source and legitimate font resources available for future revisions. Use the PDF font-identification guide to understand the document’s font list and the Acrobat editing guide for text changes.
Your questions, answered.
What is an embedded font subset?
It includes the font data needed for the characters used, rather than the whole font.
Can every font be embedded?
No. Adobe states that the font vendor’s embedding permission can restrict it.
