I’m currently using readera but it’s not that good (text scaling is behind a paywall)
I liked the PDF viewer from GrapheneOS https://play.google.com/store/apps/details?id=app.grapheneos.pdfviewer.play
Try KOREADER.
I’ve been using MuPDF for pdf’s and Libera for epubs, both on f-droid. Libera can also read pdf’s but for reasons I don’t remember, it wasn’t as usable for them as MuPDF is, at least for me. So I stayed with MuPDF.
+1 for MuPDF. It’s so lightweight it almost feels like a native part of the OS
Been using Okular on my linux laptop and its great. I wish the windows version had a better logo, but the features it comes with is awesome.
I’m surprised nobody mentioned a browser, never thought to go beyond it. Any reason people have/prefer dedicated software aside from a browser?
dark mode
native and user-created bookmarks
KOReader. The app is multiplatform (also for some e-readers and Linux) so the UI is not among the most beautiful (but I actually prefer it over Librera), but it’s feature packed, and does really well what it’s made for.
Librera reader off f-droid works great for me
Librera Reader - either from F-droid, or you can use Obtainium to install directly from repo.
Play Store version is paid but comes with additional features including network library integrations
No general reader abilities are behind a paywall though. So fdroid(free) version is recomended
I’d say you can just use a browser if it’s a quick check. MoonReader is really nice for ebooks and it cloud syncs your current spot.
MuPDF
MJ PDF is the best I could find.
SumatraPDF or zathura + zathura-pdf-mupdf/zathura-pdf-poppler
Firefox has a PDF reader built in these days.
It is pretty terrible though.
In what way? It works quite alright for me.
Bad rendering at times, jankiness during scrolling, etc.
Yeah no idea why but on Android its bad, on Linux just fine
Nah it’s crap on Linux too. Maybe not quite as bad. On Linux I generally use atril or xpdf these days.
Firefox on Linux (binary, Fedora, Flathub, compiled) is very good for PDF reading
librera
Librera Reader (Book and PDF reader) https://f-droid.org/packages/com.foobnix.pro.pdf.reader/
I’ve been using this a few months and recommend it as well. It’s serviceable but feels a bit janky. Scrolling and switching between view styles tends to leave black boxes on my device, and the UI doesn’t always disappear while scrolling. But I’d still recommend it for how light and fast it is on top of being FOSS
That’s what I’m using:

I would advise to use open-source software wherever you can. You (almost) never have paywalls, ads or trackers there ;)
