About This Tool
When reviewing formatted PDFs or preparing vector artwork for production, identifying the exact typefaces embedded in a document is essential. PDF files store font references and embedded font subsets using internal /BaseFont dictionary descriptors. This tool reads your uploaded document directly into local browser memory, scans internal stream headers, and extracts declared font families while stripping arbitrary six-letter subset prefixes. You can instantly see whether a document relies on standard system typefaces or embedded display fonts without installing heavy desktop typography utilities.
All stream decoding occurs client-side using JavaScript typed arrays. The tool inspects font descriptors and family names rather than rebuilding installable binary font files, making it a fast way to audit typography and check font licenses across customer proofs.
How to Use
- 1
Drop your PDF document into the inspection upload zone.
- 2
The browser scans the binary stream to locate /BaseFont font dictionaries.
- 3
Review identified font family names, weights, and detected format types.
- 4
Copy typography names for asset licensing or style guide documentation.
Frequently Asked Questions
How does this tool detect fonts embedded in a PDF?
The inspector decodes the raw PDF byte stream into memory and scans for standard /BaseFont postscript declarations. It identifies regular, bold, and italic variants and trims random six-character subset tags generated by PDF exporters.
Can I download usable TTF or OTF files from this page?
No. This tool audits and displays typography descriptors and font names. It does not reconstruct full standalone binary font files because embedded PDF fonts are usually partial subsets containing only characters used in that specific document.
Are my uploaded PDF documents sent to an external server?
No. File reading, stream searching, and font name parsing run entirely inside your web browser. No document data is transmitted over the internet.
