Set Acrobat as the default app on mobile
Learn how to set Adobe Acrobat as the default app for opening PDF files on your mobile device.
Setting Adobe Acrobat as your default PDF viewer ensures that all PDF files open directly in the app, giving you access to its full range of viewing and annotation tools.
Select Apps > Adobe Acrobat.
Scroll down and select Acrobat.
Select Set as default.
On the page that opens, tap Open supported links toggle to enable it.
If prompted, select Always when opening a PDF with Acrobat Reader to make it the default app.
On iOS, there isn’t a direct way to open PDFs in Acrobat by default. Instead, you can open files in Acrobat by sharing a PDF from another app using the Share menu. When you share a file to Acrobat, a copy is saved in Acrobat and opens automatically.
If Acrobat doesn’t appear in the Share menu, follow the steps below to add it manually.
Open a PDF in any app.
Tap Share or Open In (varies by app and iOS version).
Swipe left and tap More.
Tap Edit.
Tap the plus icon for Acrobat to add it to Favorites.
Turn on Copy to Acrobat.
Tap Done , then tap Done again.
Once enabled, Acrobat appears as a share option whenever you tap Share in other apps.
