You can create deeply nested outlines to reflect complex document hierarchies (chapters, sections, subsections) simply by organizing items in the editor view. This ensures your readers can jump to the exact information they need instantly.

  • Title & Author: attribution and display in PDF readers.
  • Keywords: Enhance discoverability and internal indexing.
  • Subject: Provide context for document management systems.

Yes, your document is 100% secure. We utilize advanced web technologies (WebAssembly) to process the PDF strictly on your device (client-side). Your file is never uploaded to our servers, meaning we cannot see, store, or share your data. It works exactly like a desktop application, but inside your browser.


Is this tool free? Do I need to register?

This tool is completely free to use. There are no hidden paywalls, no "pro" versions, and absolutely no login or registration required. We believe in providing accessible tools without user friction.


Why should I edit PDF Metadata?

Editing metadata (Title, Author, Keywords) is crucial for SEO (Search Engine Optimization) if your PDF is published online. It helps search engines like Google understand the content of your file. Additionally, it improves the experience in PDF readers and accessibility software by providing accurate context about the document.


Can I move bookmarks around after creating them?

Yes. The editor supports flexible management. You can change the order, nest items under parents, or promote items to top-level bookmarks to create the perfect Table of Contents structure.


What is the JSON Import/Export feature used for?

The JSON feature is a powerful tool for automation and backup. If you are working on a document and want to save your progress without saving the whole PDF, export the bookmarks as JSON. Later, you can re-import them. It is also useful if you have multiple PDFs that require the exact same bookmark structure.
