Some fonts looked wrong though - probably because the document was created on Windows machine with fonts which are absent on mine. Inkscape is a vector editor so no rasterization involved. I was able to open a PDF file in Inkscape, draw a rectangle over a piece of text and print it out. This is related to How to remove meta and sensitive data from PDF file?, but we are all on Windows, not Unix.(originally I recommened Okular but it didn't work as I expected) Inspired by Blacking out a part of a PDF, or redaction of text on AskDifferent. Foxit asks where you want to save the PDF. In the background, PDFCreator saves the file as a TIFF and then prints the TIFF to Foxit's PDF printer.Open the PDF in Foxit Reader and cover up any visible sensitive data with black rectangles.For the output, set PDFCreator to print back to FoxIt, rather than opening the document. I don't know if I should include this, since the general question will probably be more useful, but here's my specific setup: The software:Ĭhange the settings in PDFCreator so that it converts the document to a TIFF, instead of a PDF. Would this work? Does the TIFF file preserve any information about objects or layers? Is any potentially sensitive metadata likely to make it through, or will all metadata be changed, as I hope?.
Then convert the TIFF file back to a PDF. In some PDF program, cover up the sensitive stuff with boxes, then convert it to a TIFF file. I'm having trouble figuring out why this wouldn't work. If you are of this opinion, please explain why.
Many forum members posting about this topic have stated quite firmly that only Adobe Acrobat or other paid software can do this securely. However, I have also found that I don't know nearly as much as I think I do. I have convinced myself that this will effectively destroy potentially sensitive client metadata from the original document, as well as making it impossible to remove any black bars covering up sensitive information. We get a lot of scanned documents and our client requires that sensitive information be redacted from PDFs before they are uploaded to their system. My boss asked me to come up with a way ordinary users can redact information from PDF files using free software.
