A PDF writes its font names for machines: ABCDEF+TimesNewRomanPS-BoldMT is a subset of Times New Roman Bold, and “Arial,BoldItalic” is a request for a font the file may not carry at all. Every resource that can draw text is walked — pages, nested drawing objects, annotation appearances and the form's own defaults — and each font becomes plain facts: the family you would search for, the style, the pages it appears on, whether the program travels with the document, and whether its text can be copied back out as real characters. Two risks get named: a font that is not embedded shifts the layout at the printer, and a font with no ToUnicode map copies as gibberish. The file is read on your device.
Features
Family and style parsed out of the raw name, with the name as stored shown underneath
Embedded, subset or substituted — and which of the standard 14 a reader would swap in
ToUnicode noted per font, warned about only where copied text would really break
Pages listed as compact ranges, plus the fonts used only by form fields
Font type spelled out: Type 1, TrueType, Type 0 with CFF or TrueType outlines, Type 3
Families grouped with their styles, every name copyable in one click
Filters that narrow the table to fonts which are not embedded or have no character map
The list copied as text, or the full table downloaded as CSV
How to use the PDF Font Finder
Drop the PDF onto the page
Read the four counters: fonts, not embedded, no ToUnicode, subsets
Switch to the Not embedded filter before anything goes to print
Copy the list, or take the CSV for a pre-press check
Example
Input
brochure.pdf — 12 pages
Output
9 fonts · 2 not embedded (Arial Narrow, Wingdings) · 1 without ToUnicode · used on pages 1-4, 9
Arial Narrow is not one of the standard 14, so the printer has to own it.
Common errors & troubleshooting
No fonts are listed at all. — The pages hold pictures rather than text — a scan or a flattened export. PDF OCR adds a searchable text layer, and the font it uses then appears here.
Every font name starts with six random capitals. — That is a subset tag and it is normal: only the glyphs the document actually uses were stored. The family name after the plus sign is the one to search for.
A font is embedded but its text still copies as nonsense. — Embedding and character mapping are separate things. Check the ToUnicode column: without that map a reader has nothing to turn the glyph codes back into characters, which is also why search fails.
A row says the font object is malformed. — The descriptor could not be parsed, so embedding is unknown rather than absent. Repair PDF often rebuilds those objects, after which the row resolves one way or the other.
Frequently asked questions
Can it name the typeface used in a scanned page?
No. It reports the fonts the file declares, and a page that is only a photograph declares none. Matching a typeface from an image is a different job; run PDF OCR first if what you need is searchable text.
Which fonts are safe to leave out of a document?
Only the standard 14 — Helvetica, Times, Courier, Symbol and ZapfDingbats with their styles — which every reader must supply. Anything else that is not embedded is drawn with whatever the machine happens to have installed, and lines can reflow.
Does listing the fonts let me extract or install them?
No, deliberately. Names, styles, encodings and embedding state are reported; the font programs stay inside the PDF, where their licences expect them to be.
Why is one font listed against “form fields” instead of a page?
Because it is named in the form's default resources rather than in any page. That is the typeface a viewer reaches for when somebody types into a field.
Can the font list be read out of an encrypted PDF?
Yes. Names, numbers and structure are never encrypted in a PDF, so families, types and embedding still read without the password — only text strings and stream contents stay closed.
