Open files flight mode

Hi there

I hope you're doing well! Thank you for reaching out.

If you want to open a file offline, you need to save a copy of it to your device’s local storage. Here’s how you can do it:

1. Locate the file you want to save.
2. Tap on the three dots (⋮) next to the file name.
3. From the menu that appears, select "Save a Copy."

Once the file is saved to your device’s local storage, you will be able to access it even without an internet connection https://helpx.adobe.com/acrobat/mobile-app-faq.html
