But I have not found a simple solution for Linux. On macOS, there is the excellent PDFPen Pro. Occasionally, I want to redact text from a document, typically a PDF, before I share it with someone. From the testing I have done, it does remove the redacted text, but this is my limited testing, and I am not the NSA. It is the completely wrong thing to use if you do not trust the PDF that you are redacting, because it opens it to convert it. Warning: this is a 'quick and dirty' approach.
