I am looking for a solution to collaborative PDF editing (mostly annotations). I already have a Nextcloud installation with Office for several members so it would be great if it could be integrated, but it is not necessary.

What I mainly want is the possibility to add and view annotations made by several users on the same file at the same time.

Do you have a suggestion?

I will look into these, do you know if they support collaborative annotations?

Stirling PDF

https://docs.stirlingpdf.com/Functionality/Read-and-Annotate/

Read & Annotate is a full-featured PDF viewer that lets you:

  • Read PDFs in a clean, focused interface
  • Add annotations, comments, and notes
  • Highlight and markup text
  • Draw freehand on pages
  • Add shapes, arrows, and callouts
  • Insert text boxes and sticky notes
  • Collaborate by marking up documents
  • Save annotated PDFs for sharing

Think of it as your digital PDF notepad - read, review, and mark up documents all in one place.

It says it do. Other than that, I've never deployed it.

I have an installation of Stirling PDF, but in my short experiment it had no ability to collaborate on the same document.

Every edit created a new copy of the document downloaded to the user. The annotations weren't tagged to the individual user and sending different versions of a PDF from user to user is not what I am looking for.

Stirling is a single user software in that regards. I haven't tested the also mentioned BentoPDF but I suspect it to be the same as it is also trying to be a PDF toolbox like Acrobat. PdfDing has a slightly different approach it might be an option if OnlyOffice does not work out.

Hmmmm...sorry to steer you wrongly. I mean, gosh it says it does all annotation and collaboration. I assumed 'collaboration' to mean multi-user collaboration. Hard to collaborate by yourself.

I am thankful for any input. Maybe it helps someone else looking for a similar thing.

I think the collaborative part means sending PDFs from user to user and maintaining the ability to edit annotations. That may work for many use cases - a lot of businesses may be fine with that when email is still the communication medium of choice.
