PDFSyntax is a pure-Python, dependency-free library for inspecting and transforming the internal structure of PDF files down to the byte level, with non-destructive incremental updates. It also ships a CLI for quick insights (metadata, fonts, text, structure dumps) and an HTML browser for the PDF's internal objects.

Use cases

• inspect the internal structure of a pdf file
• read pdf metadata like title and author in python
• modify pdf objects without rewriting the whole file
• extract text from a pdf with layout
• list fonts used in a pdf
• browse a pdf's internal objects as html
• dump pdf file structure from the command line

When to choose

• you need low-level, byte-level access to PDF objects and syntax
• you want a lightweight, zero-dependency pure Python tool
• you prefer non-destructive incremental edits to PDFs
• you want quick CLI inspection of PDF metadata, fonts, or text

When to avoid

• you need stable, production-grade PDF manipulation - the API may change anytime (beta)
• you need high-level document generation or heavy rendering features
• you need mature text extraction with full layout detection (still on the to-do list)
