I’m building a lightweight PDF editor focused solely on letting users change the text already inside a PDF—no merging or annotation features required. I need a functional prototype that opens an existing file, lets me revise its text in place, and then saves a clean, updated PDF. Core functionality • Edit existing text layers directly inside the PDF. • Basic text editing only: change font size and style, switch bold / italic formatting. • Preserve the document’s original layout and fonts after each change. • Export the modified file without quality loss or unwanted watermarks. Tech expectations You’re free to work with PDF.js, Apache PDFBox, iText, pdf-lib, or any library you trust, provided the end result runs on Windows and can later slot into my wider application. Clean, well-commented source code and a concise setup guide are part of the deliverable. Hand-off items 1. Source code and compiled build (if applicable). 2. Quick start documentation covering dependencies and build steps. 3. A short screen-capture demo that shows opening a sample PDF, changing font size/style and toggling bold/italic, then saving the updated file. When you reply, let me know: • The tech stack you plan to use. • How long you’ll need for the initial prototype. • Examples of similar PDF manipulation work you’ve completed. I’m ready to move quickly once I find the right fit.
