A PDF SDK That Actually Edits Text — No Broken Layout, No Scrambled Characters
Most PDF libraries read and extract. When they try to edit, fonts break, characters scramble, and layouts collapse. PDFDancer modifies text directly inside the PDF structure — fonts, spacing, and design stay intact. Available for Python, Node.js, and Java.

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.
How It Compares
PDFDancer vs. Typical PDF SDKs
Most PDF SDKs overlay new text on top of old content, flatten pages to images, or require you to rebuild documents from scratch. PDFDancer edits the actual PDF structure.
| Capability | PDFDancer | Typical PDF SDKs |
|---|---|---|
| In-place text editing | Yes | Overlay / flatten |
| Font preservation | Embedded fonts reused | Font substitution |
| Automatic text reflow | Yes | Manual coordinates |
| PII redaction | Binary-level removal | Cosmetic overlay |
| Semantic selection | By content / regex | By x,y coordinates |
