Flatten PDF using Ruby

Flatten PDF to prevent unwanted changes

Flatten PDF Ruby library is a tool that allows you to lock PDF form fields and prevent further modifications of the values entered into the PDF forms. It also provides an option to prevent text selection, copying, and extraction by turning the textual symbols into vectorial paths to make the PDF read-only while preserving the original vectorial PDF quality.
