I am in a struggle with the Home Office. I have to fill out multiple forms repeatedly. I bought Adobe but it did not work. This software is very straightforward and I am sharing the document with my Barrister, which saves me money, time and avoids confusion

Select a file in the PDF Viewer file browser by long pressing on the cover image of the PDF. This will start the multi-file selection mode. Select additional files for merging by tapping them. Once you're done selecting files, press the merge icon in the multi-file selection bar at the bottom.
File Locker To lock a file, you will have to simply browse it and long tap on it. This will open a popup menu from which you will have to select the option Lock. You can even batch select files and lock them simultaneously. After you select the lock file option the app will ask for a password to encrypt your files.
Run the tool, click on Add files / Add Folder option to insert PDFs & enter the password. Click on the Merge option and hit the Next button. Choose the desired Merge option and select the destination path.
