Alpha PDF app for iPhone and iPad

This app allows you to manage, edit and sign PDF documents as well as create new ones either by adding them from external sources such as iCloud drive, or by creating them from images, scans or other supported media files. You can also add documents using the build-in document scanner, or by taking a photo or browsing the photo library. Instantly share the results with your friends or colleagues.

A quick summary of what you can do from within the app:
• Organize your documents library with a few taps
• Create PDF documents from images
• Preview and share imported or created PDF documents
• Sign PDF documents using a digital certificate¹ with custom visual template and add timestamp to this digital signature
• Extract images from the PDF documents²
• Add documents for processing using a built-in scanner
• Edit document pages (arrange, rotate, delete) and save the result
• Work with password-protected documents
• Set password for PDF documents and encrypt them
