Hi c/programming,
for quite some time I have been working on the open-source project PdfDing - 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.
Last week PdfDing was selected to receive a grant from the NGI Zero Commons Fund. 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 and need to share it with the community.
PdfDing’s features include:
- Seamless browser based PDF viewing on multiple devices. Remembers current position - continue where you stopped reading
- Stay on top of your PDF collection with multi-level tagging, starring and archiving functionalities
- Edit PDFs by adding comments, highlighting and drawings
- Manage and export PDF highlights and comments in dedicated sections
- Clean, intuitive UI with dark mode, inverted color mode, custom theme colors and multiple layouts
- SSO support via OIDC
- Share PDFs with an external audience via a link or a QR Code with optional access control
- Markdown Notes
- Progress bars show the reading progress of each PDF at a quick glance


I am thrilled to learn about this! I am an Accessible Document Specialist (ADS). Reliance on Adobe is frustrating. Current PDF viewing and editing applications do not support the PDF 2.0 specification or its companion PDF/UA-2 specification for accessibility. Support for MathML within PDF documents would be a game changer. Have you looked into MathML support?
