Om dette verktøyet

Permanently black out sensitive content in a PDF. Privvert flattens every page that has redactions to an image, so the underlying text is truly removed - not just visually hidden by a black rectangle that anyone could move aside in a PDF editor.

This matters for legal disclosures, public-records releases, FOIA responses, journalist source protection, and any document where a sloppy redaction could leak the underlying text. The whole process happens in your browser.

True redaction removes content - it does not just cover it. Privvert deletes the underlying text objects, image regions and form fields inside the redacted rectangle and replaces them with an opaque black fill, then flattens the page so the redaction cannot be reversed by selecting, copying or editing the PDF. This is the same approach government and legal redaction tools use, and it is the reason simply drawing a black rectangle in Preview or Acrobat <a href="/blog/pdf-redaction-black-rectangles-do-not-work">does not work</a>.

Ofte stilte spørsmål

Can the original text be recovered?

No - pages with redactions are re-rendered as images, so the underlying text is no longer present in the file. This is the difference between proper redaction and 'black box on top of text' which can be reversed by anyone with a PDF editor.

Will text on un-redacted pages stay selectable?

Yes. Only pages that have at least one redaction are flattened. Other pages keep their original text and structure.

Are EXIF or metadata redacted too?

Use the PDF Metadata tool to clear document properties. This tool covers visible page content; metadata is a separate layer.

What about embedded files or attachments?

Embedded files are not modified by this tool. If your PDF has attachments, remove them in a separate pass with a desktop PDF editor.

Why is drawing a black box not enough?

Black rectangles in most PDF editors sit on top of the text - the underlying characters are still in the file. Anyone who opens the PDF can select the hidden text, copy it, or remove the rectangle. Real redaction deletes the content first, then covers the empty space.

Does this also remove metadata?

Yes - document metadata (author, software, edit history) is stripped during the redaction pass. The output is a clean PDF safe to share. For the broader picture, see the PDF metadata guide.
