pdf-form-tools 2.0.1

Template-aware tools for filling scanned PDF forms with visual verification

pdf-form-tools

pdf-form-tools is an import-only Python package for filling layout-sensitive scanned PDF forms with deterministic placement helpers and visual verification primitives.

It is intentionally small:

• render PDF pages to raster images
• detect writable regions, checkbox boxes, signature lines, and ID slots
• draw text, checks, and signatures onto an overlay
• merge the overlay back into the original PDF

Install

python -m pip install pdf-form-tools

Supported Python versions: 3.11 through 3.14.

Example

from pathlib import Path

from pdf_form_tools import Rect, merge_overlay_pdf, render_pdf_page

source_pdf = Path("form.pdf")
preview_png = Path("preview-page1.png")
render_pdf_page(source_pdf, 0, 2, preview_png)

# draw your overlay separately, then merge it back
merge_overlay_pdf(source_pdf, Path("overlay-page1.png"), Path("form-filled.pdf"))

Development

python -m pip install -e ".[dev]"
python -m ruff check .
python -m pytest -W error::DeprecationWarning
python -m build

Scope

This package contains reusable low-level helpers only. Form-specific filling flows belong in project-local scripts or thin runners, not in the shared library.
