Some PDFs have fonts that are too large to maintain an optimal reading speed. Is there a normal page-scrolling (not flipping) PDF viewer that can stay zoomed out at the zoom level you've pinched to? Everything I have tried so far automatically zooms back to 100% after releasing the pinch-zoom.
Found this thread, by searching for an answer to the same problem.
By Providence, I did find an alternate app, which accomplishes this ability to "zoom out" (to less than 100%, etc.), on a PDF.
However, it can tend to be somewhat tricky — but not at all impossible — to get the file into the app, in the first place.
(You'll figure it out, if you have enough initiative to download the app, and to tinker around, with it).
Here is the name of the app: "PDF Editor ,PDF Book Reader" by Milad Fakhr
I hope that helps!...
I have found two apps that can do this:
(free) MarginNote has a vertical scrolling mode (though it's not the default) and can stay zoomed out at about 50%.
(requires IAP subscription for this option) PDF Viewer by PSPDFKit GmbH has a vertical scrolling mode (though it's not the default) and can stay zoomed out at about 50% (Settings -> Advanced -> Extended Zoom Out)
I’ve just discovered this problem and the best solution I’ve found is using the iOS app ‘Goodnotes’ from the App Store. I’ve imported the offending .pods and not only can I now scale the reading I can also annotate with the Apple Pencil and re-export in a ton of different formats.
Really elegant bit of software. It’s a paid program but is absolutely worth every cent.
