What is PDF Font Inspector?
PDF Font Inspector analyzes, inspects, and catalogs all typography assets embedded inside a PDF document. When troubleshooting missing character glyphs, checking whether proprietary fonts are legally embedded or subsetted, or auditing documents for PDF/A print preflight compliance, this tool scans the internal font descriptor dictionary and displays font family names, encoding formats (TrueType, Type 1, OpenType), and embedding statuses. It provides full technical visibility into document typography, font weights, and character sets in seconds.
