If you want to permanently delete information or content in PDF documents, just use PdfEditor's 'Redaction' function. Permanently redact sensitive, confidential or personal information from PDF documents. Redacted contents can not be restored!
Using the redaction tool select all the areas in the PDF document that you want to delete permanently.
As long as you are in redaction mode, selected areas can be changed, extended or deleted. When hovering with the mouse, content within redaction areas is displayed semi-transparently.
Only when you choose 'Apply Redaction', previously marked areas are permanently and irretrievably deleted from the PDF.
Please always make sure that you have a backup copy of the original PDFs, because even with PdfEditor redaction can not (!) be undone.
PDF documents often contain "hidden" information, so-called META information. Applying 'Redaction' to the PDF, metadata is automatically controlled and can be deleted.
Of course, the data can also be redacted using the menu command "File - Properties".
