This is already possible. In the pdf overview there is a layout button on the top right where you can change between compact, list and grid layout.

I just tried using the download attribute out. I am also using librewolf and even with the download attribute it will open a new tab when the default behaviour (applications -> pdf -> open in librewolf) is enabled.

Thank you for your feedback!

1. this is only for the demo mode. I don’t want to have user files on the demo instance. On the log in screen of the demo instance, there is also note regarding this.
2. this might be because of your browser. are you using a firefox based browser by any chance? I had the same issue and had to adjust this behavior in the settings.
3. you are right. I already made the changes, so this is fixed.

I’ll think about the other two suggestions.

I started to develop PdfDing because I wanted to continue reading where I left of regardless of the device I am on. That’s not possible with a standalone app.

Without more information I am kind of guessing. But probably you need to set the HOST_NAME env variable to the address (e.g. pdfding.homelab) you try to access the app in the browser.

Allow me to quote myself:

While Stirling PDF and PdfDing are both self-hosted web applications centered around PDF files, they still differ in their use case. Stirling PDF focuses on performing various operations like splitting, ropping and rotating on your PDFs. PdfDing however has a different focus, it is all about reading and organizing your PDFs. All features are added with the goal of improving the reading experience or making the management of your PDF collection simpler. PdfDing’s editing functionalities were added with the same idea in mind. You can add annotations, highlighting and drawings to PDFs, so that you can highlight or add information that will be beneficial to your reading experience.

The project is using mozilla’s pdf.js library for displaying pdfs (this is also used for firefox’s build in pdf reader). As far as I am aware it should be able to work with (allmost) all pdf files.

It is not planned right now as I never developed an android app before. But who knows, I am also not a frontend dev, yet here we are :D

I am planning on developing a Rest API, hopefully I can do this in such a way that someone from community is able to create a mobile application.

No this is not possible. However I think, that you can adjust the page size/scale with Stirling PDF.

It depends on you use case. Stirling PDF focuses on performing various operations like splitting, cropping and rotating on your PDFs. PdfDing has a different focus, it is all about reading and organizing your PDFs. I started this project because I wanted a web app where I can read longer PDFs seamlessly on my desktop and mobile devices.

The newly added editing features were implemented with the aim of improving the reading experience. If I find something important I can add an annotation or highlight something. When studying you can add free hand notes to your files.

I hope that helps in differentiating the two applications.
