Use Adobe Acrobat on a Desktop Computer
Since the iOS app lacks advanced encryption features, transfer the file to a PC or Mac to apply AES encryption.
The Adobe Acrobat mobile application is designed for quick edits and viewing, meaning it omits advanced security configurations like AES encryption. To fully secure your document, you must use the desktop version of Adobe Acrobat.
Send the PDF file from your iOS device to your desktop computer via AirDrop, email, or a cloud storage service like iCloud or Google Drive.
Launch Adobe Acrobat Pro or Standard on your PC or Mac and open the transferred PDF document.
Navigate to 'Tools', select 'Protect', and choose 'Encrypt with Password'. From the compatibility dropdown, select 'Acrobat 7.0 and later' or higher to enforce AES encryption, set your password, and save the file.
Use a Third-Party PDF Security Tool
If you do not have access to Adobe Acrobat on a desktop, use alternative desktop software or a trusted online PDF encryption tool.
