MuPDF mini (version 1.23.3a): Minimalist viewer for PDF, XPS, CBZ, unprotected EPUB, and FB2 documents

mupdf is the mupdf of epub; it supports epub and other formats beyond pdf¹. When I've had really large files I've used mupdf to read them a few times, as it seems to be far better at handling them than other tools.

Doesn't exactly fit your requirements, but might as well mention it here: muPDF - the most lightweight PDF viewer that I've ever seen. You don't even have to install it. Mobile version exists by the way.

I don't see anything about that on ArchWiki or MuPDF's website. Could you provide details on how it is obsolete and what critical vulnerabilities it has?

I think you might mean PyMuPDF (https://github.com/pymupdf/PyMuPDF), a Python library built on top of the MuPDF C library (https://mupdf.com/).

PyMuPDF and MuPDF are both available under dual open source AGPL and commercial licenses. They have been around for many years and are under continual development.

[Disclaimer, i work for Artifex, who wrote MuPDF and recently acquired PyMuPDF.]

I actually have my own little nextcloud instance running on a $5/month digital ocean virtual private server. My intent was for family (only 3 people) and i to use it...but honestly, most of the time it is only me. I draft conventional old text files (though i do use markdown)...and save the files in a nextcloud folder to enable sync anywhere. For actually synching and drafting of the text/note files, i have the nextcloud mobile app as well as the nextcloud notes app on my phone (https://github.com/stefan-niedermann/nextcloud-notes)...so now i can jot down notes anywhere that i carry my phone. I do lack some advanced features that zim wiki would bring, like linkages, some color formatting, styles...but for my workflow i found them not to be ultra necessary anyway. Side note: i use nextcloud for general file synching, rss/feed reading, and other functions...so it was not setup only/specifically for notes...the note taking just came along as an extra benefit. Any headaches in managing my own nextcloud instance (and just like managing any of your own infrastructure, there are always costs), are outweighed by all the features that i legitimately use/benefit from nextcloud.

If you use nextcloud, you could also use other text editors on mobile phone like joplin, qOwnNotes, etc. - so you are not stuck only with the nextcloud notes app. Also, if you are not an adherent to open source software, my workflow can also be used via dropbox, box.com, onedrive, etc. too i suppose (you're just drafting notes on the road and saving them up to someone e;lse's server/cloud). I hope that helps!
