PDF readers with capability of commenting/editing pdfs on the SD card?

graatch · 06-12-2021, 06:30 AM

Hello, I wonder if there are any PDF applications that can make changes (highlights or comments, for example) to a file on the SD card, that is to say, without making an internal-drive copy and editing that instead. I believe it's possible but hard for the app coders to do and usually they don't bother.

However I hope someone has bothered because it's very annoying. (I don't know why this additional layer of security was necessary in the first place, or why an SD card needs to be protected when the internal isn't, way back when Android 5.0 was released.)

So far I've checked Moon Reader (can only make an internal copy), Foxit (can only make an internal copy), Adobe Reader (can only make an internal copy).

Anything you folks know of?

Xodo works. It will ask if you want to make a copy but you can just ignore that and it will let you annotate directly on a file saved on the SD card. I confirmed this by opening the file in another PDF reader and the scribbles showed up. I did need to enable annotating with my stylus in settings though.

Nice, thanks so much.

I've found Xodo best so far for my 10" Android tablet and better than anything Windows on a 10" Win 10 tablet.
But I've not used annotation.

There seems to be a paid pro version.

Xodo has a Windows version too actually designed for tablets but also works on PCs that's in the Microsoft store. It's pretty great too and since it's a UWP app it plays nicer with LaTeX as you don't need to make sure it's closed when compiling unlike normal Windows PDF apps like Acrobat.
