I need to send a pdf containing bank details about a payment, only some of the data in the pdf is relevant to the receiver, and I would like to hide everything else.
I have opened the PDF in preview and I put white squares on all the numbers I want to hide, and "printed" it to a new PDF.
When I open the new PDF all the data is invisible, but I can still select the text using the mouse, copy it, and paste it to a text document. All the data is still there, easily accessible.
How could I delete the data for good so that it's not there any more?
here's a screenshot of me selecting the data although it's hidden:

Open it with a PDF editor, like Acrobat Standard, and actually remove the text you want gone, then save it.
