\"\"<\/a><\/p>\n

For those want to unlock \/ decrypt PDF files, there’s now a stupid simple graphical tool to do the job in Linux.<\/p>\n

It’s easy to encrypt you PDF files in Ubuntu Linux since the built-in LibreOffice office suite has the option on ‘Export as PDF’ dialog. However, there seems no easy way to remove password for PDF file, other than using qpdf<\/code> command:<\/p>\n

qpdf --decrypt --password=<PASSWORD> input.pdf output.pdf<\/pre>\n
unlockR is a new GTK4 application that use Libadwaita to provide a modern simple user interface to decrypt your PDF files.<\/p>\n
\"\"<\/p>\n
It’s so simple that you just need to click ‘Open a File<\/i>‘ to select your PDF, then type the password, and finally hit ‘Decrypt’. It doesn’t change the original file, but generates a new PDF without password protect.<\/p>\n
\"\"<\/p>\n
As the picture shows, it has both light and dark mode that switches automatically according your system color scheme.<\/p>\n
NOTE: This app is NOT about to crack password on a PDF file. You need the password to be able to decrypt it.<\/b><\/p>\n
How to Install unlockR<\/h3>\n
It is a free open-software software works on both Linux and Windows. For Windows package, just grab the zip from github releases page:<\/p>\n
