  • How to safely remove a PDF password on Linux (Ubuntu)

    A common answer to remove a PDF password is to run: qpdf –password=supersecret –decrypt input.pdf output.pdf This approach isn’t secure because it stores your password in terminal history (like .bash_history). Here’s how to fix that: In case you don’t have qpdf, just run sudo apt install qpdf.
