Name: PDFDancer Python SDK — Edit PDFs in Python
Author: PDFDancer

Python PDF library that truly modifies text in place. Find-and-replace with automatic reflow, HIPAA-compliant redaction, fill templates programmatically. No flattening. No image overlays. Precise text editing.

This Is PDFDancer

Open. Find. Replace. Save.

PDFDancer treats PDFs like editable documents. Select content by what it says — not where it sits on the page — then modify it. The PDF handles the rest.

Semantic selectionFind paragraphs by their content, not x/y coordinates

In-place editingText is modified inside the PDF structure — no overlays

Automatic reflowLonger or shorter replacement? Spacing adjusts automatically

What You Get

Built for How Developers Actually Work with PDFs

In-Place Text Editing

Text is modified directly inside the PDF structure. No overlays, no image layers, no document rebuilds. The edited PDF is indistinguishable from the original.

Automatic Reflow

Replace a 10-word sentence with a 20-word one. PDFDancer adjusts line breaks, spacing, and paragraph bounds automatically. No coordinate math.

Font Preservation

The original embedded fonts are reused for replacement text. No font substitution, no rendering differences, no visual artifacts.

Semantic Selection

Find content by meaning, not position. Select "the paragraph starting with X" or "all lines matching this regex" — across pages, automatically.
