AI interpretation — verify before relying

AI-generated interpretation of the package facts above; every digit, version, license, or vulnerability id it cites is grounded in the facts already shown on this page

pydyf is a low-level PDF generator that writes PDF files directly according to the PDF 1.7 specification, with no runtime dependencies.

Installation is frictionless—a pure-Python wheel with zero runtime dependencies. Maintenance shows aging status (254 days since last release), but the repository remains active with recent commits and the package supports current Python versions through 3.14.

pydyf is licensed under BSD (permissive), meaning you can use, modify, and distribute it freely in both open-source and commercial projects with minimal restrictions.

Usage

pip install pydyf

import pydyf

document = pydyf.PDF()
page = pydyf.Page(document)
page.show_text('Hello, PDF!')
document.write('output.pdf')

Requires Python 3.10 or later.

Verdict: pydyf is a stable, dependency-free PDF generator suitable for projects needing direct control over PDF output. Its permissive BSD license and zero install friction make it accessible, though the 254-day release gap suggests a mature, maintenance-light project rather than an actively developed one. No known vulnerabilities.

Needs verification

Whether the aging maintenance status reflects intentional stability or reduced upstream attention.
Performance characteristics and PDF feature completeness relative to other generators.
Specific API methods and parameters supported by the pydyf.PDF and pydyf.Page classes.
