Create and review in C#

  • Write loops and conditions in plain C#, not a template language
  • Build reusable components from ordinary classes and methods
  • Get IntelliSense, type checking and refactoring in your IDE
  • Keep layouts in Git beside your application code

Develop with AI agents

  • Migrate legacy HTML-based reports to QuestPDF with AI
  • Create and modify documents confidently through prompts
  • Deliver new documents and changes significantly faster
  • Keep every AI change type-checked and easy to review

Preview, inspect and debug

Add one line of code and your document opens beside your IDE. With hot-reload, every change appears in the preview at once: no recompiling, no reopening PDFs.

  • Explore and navigate the document structure
  • Magnify details and measure distances
  • Jump from the preview to the matching code
  • Debug exceptions and layout issues
