🚀 Built a Full PDF Editor on Top of PDF.js – PDF Master Studio

Hi everyone,

I wanted to share a project I've been working on for quite some time: PDF Master Studio, a desktop PDF editor built on top of PDF.js.

First, a huge thank you to the PDF.js team and everyone who has contributed to the project. PDF.js provides an excellent rendering engine, and it made this project possible.

Starting with PDF.js as the rendering foundation, I built a complete editing layer around it, including:

• ✏️ Direct text editing
• 🔤 Font detection and matching
• 🎨 Text formatting (font size, color, bold, italic, underline)
• 🖼 Image replacement and editing
• 📄 Page management (merge, split, rotate, reorder)
• 📑 PDF to HTML reconstruction
• 💾 Export edited PDFs
• 🖥 Windows and Linux desktop applications (Electron)
• 📱 Responsive interface

One of the biggest challenges was transforming a PDF viewer into an interactive editor while keeping document layout and positioning as accurate as possible. I spent a significant amount of time working on text reconstruction, coordinate mapping, font handling, rendering synchronization, and export fidelity.

Although there is still room for improvement, I'm proud of how far the project has come and wanted to share it with the PDF.js community that made it possible.

I'd love to hear your feedback, suggestions, or ideas for further improvements.

Thanks again to the PDF.js maintainers and contributors for building such an incredible open-source project.

Congrats! 🙌 This looks VERY cool.

There is a tragic lack of a basic foss PDF "viewer + basic editor" solution for Linux; one that can do a bit more than highlighting and annotations. I have been using PDF.js for a while because it allows me to insert images, draw, and insert text, but for other basic operations like moving or deleting pages, inserting, merging, and extracting pages, I have to resort to PDF Arranger, which nice but inadequate as a viewer, and cannot do other things.

I think your project is moving in the right direction and it should receive more attention and recognition. Bravo! 👏

There are many things that I like, but what I would love the most would be to integrate its most important capabilities into PDF.js itself, retaining the core part of the viewer. These could be under a menu, or activated in the sidebar icon, to avoid clutter when exclusively reading.

I am not good enough a programmer to do it myself, but a man can dream.

Thanks, and keep up the good work! ❤️ 💪

I also wonder if this kind of tools can be distributed as a single HTML (huge) file (embedding all dependencies) and openable via file:///?
