Hi c/Open Source,

after quiet 6 months I am back with great news about PdfDing. I am very happy to announce that PdfDing is receiving a grant from the NGI Zero Commons Fund: nlnet.nl/news/2025/20251016-selection-NGI0CommonsFund.html. This fund is dedicated to helping deliver, mature and scale new internet commons across the whole technology spectrum and is amongst others funded by the European Commission. The exact sum of the grant still needs to be discussed, but obviously I am very stocked to have been selected in this funding round as one of the few projects that can be selfhosted. It’s also great timing, because the past half year has been very busy both in my private and professional life, but in the coming months I finally have time again to continue improving PdfDing.

PdfDing is a selfhosted PDF manager, viewer and editor offering a seamless user experience on multiple devices. You can find the repository here. As always I would be quite happy about a star and you trying out the application.

Nice!

For someone unfamiliar, can you explain why someone would host PDFs? Are there any organisations that already do this?

Also, what would be the difference between this and pdf.js (e.g. Firefox viewer) when it comes to the viewer?

    In short: Managing and consuming PDFs seamlessly on multiple devices. You can continue reading on your mobile device were you stopped reading on your laptop. I started implementing the app as there was no other app that satisfied my requirements:

    • Complete control over my data.
    • Easy to self-host via docker.
    • Lightweight and minimal, should run on cheap hardware
    • Continue reading where you left off on all devices
    • Browser based
    • Support single sign on via OIDC in order to leverage an existing identity provider
    • PDFs should be shareable with an external audience with optional access control
    • Open source
    • Content should not be curated by an admin instead every user should be able to upload PDFs via the UI

    Surprisingly, there was no solution available that could do this. In the following I’ll list the available alternatives and how they compare to my requirements.

    That goes straight into my bookmarks! I’ll look into this later but it looks very nice and promising.

    Ooh, does anyone know of something like this which can show 3 pages at once?

    Thinking of replacing the music app on an old mac mini and using a hdmi stick/pi to display it instead.

    Serious question. I've seen a few posts now about self-hosting PDF managers. Why is this useful? Why not just open a PDF application when I need to work with PDF?

    I have lots (100s?) of pdfs for ttrpg rules collected over years - storing in folders is enough to separate by game, but fails when a single book is a mix of content - does it go in the adventure, character options or DM folder?

    Having a nice UI with tags and searching would help to organise the collection a lot better.

    Accessing all of that across any of my devices while the files actually live on my NAS would a be a big improvement - its easy for my laptop & tablet to get out of sync etc

    This looks great - thanks for all your efforts! :)

    I plan to setup a service to better wrangle all of my many ttrpg PDFs soon and this will definitely be in the mix.
