Moon+ Reader PDF blowing up

BillSeitz · 03-25-2026, 04:45 PM

I have a 25MB PDF I'm trying to read.

It was going fine until I toggled from raw-text to scan-view mode (not sure if those are the right words).

I first his this on my ChromeBook. The current state is that if I open that book, I briefly see the scan-view, then it "crashes" and returns me to RecentList. I've rebooted the tablet and made this my first action, so I have max memory, but it hasn't helped.

Then I tried loading the book onto my Pixel6, in hopes that I could clear something in the book-state... unfortunately clicking on the book goes straight into the scan-view. The only difference is that it automatically retries/recrashes a bunch of times, before the app itself dies.

On both platforms I've tried tapping multiple times on the screen while the app is working, to try and change the render-mode, but I never get that button to pick. (And even if I get chapter-list button pressed, that view starts to open up but then the app dies.)

Do I need to wipe out the highlights/setting file for the book? How do I even do that on Android/Chrome where many files types are rather hidden?

I don't use Moon Reader but is "scan-view mode" something like PDF Reflow? If so you could try another app (maybe Librera which reflowed some PDFs very well for me, some on the other hand not so well) or convert the PDF to epub in Calibre.
Or is "scan-view mode" just OCR? In that case using OCR in a PDF app on your computer may be another option to try. And then upload the OCRed PDF to your Chromebook or Pixel.
