PDF debugger


This tool allows you to inspect the tree structure of a PDF file. It is built using the Mozilla/PDF.js library. I made a fork of the project and extracted only the core part of it and published it as separate npm package pdf.js-core

Source code

The source code is available on GitHub


This tool doesn't upload your PDF files anywhere. It processes them locally in your browser. One thing that you must consider is that I'm using Posthog analytics to track visitors, which has a screen replay feature.
