PDF Add Text Tool

The tool enables precise overlay of user-provided text onto existing PDF pages. It targets document editors, researchers, students, legal and administrative staff who need annotations, captions, form notes, or corrections without altering the original content. It supports batch processing in automation workflows for consistent overlays across multiple PDFs.
Conceptually, the tool renders the input text as a vector overlay at a specified page, coordinates, and style. It preserves page geometry and existing content, producing a new PDF while keeping the source unchanged. Outputs can be named by the user or inferred from the input, enabling seamless integration into templates and archives.
Core features include per-page positioning (page number, x and y coordinates), font controls (family, size, weight), color, and optional rotation. Advanced options cover text wrapping, alignment, and opacity. The tool ensures the overlay remains legible against varied backgrounds and respects margins and bleed areas to avoid clipping.
Error handling covers missing inputs, invalid page references, coordinates outside page bounds, oversized text without wrapping, and password-protected PDFs without access. When validation fails, the tool returns explicit error codes and prevents file generation. It also detects and prevents overlays that would obscure critical existing elements.
Industry standards followed include coordinates in points (1 inch = 72 points), RGB hex colors, and standard font rendering. The solution assumes US Letter or A4 size by default unless overridden. It does not OCR, redact, or alter existing text, and it excludes secure PDFs without a provided pass-through permission.
