What Is PDF Redactor?
PDF Redactor permanently removes sensitive information from PDF documents. Unlike simply covering text with a black box, true redaction eliminates the underlying data so it cannot be recovered — critical for legal discovery, FOIA responses, medical records, and any document containing personal information.
How to Use This Tool
Upload your PDF and use the selection tool to mark areas for redaction. You can redact text passages, images, or entire regions of a page. When you apply redactions, the tool permanently strips the selected content from the document. Download the redacted file — all processing happens in your browser.
Why Use PDF Redactor?
Improper redaction (like placing a black rectangle over text) is a common and serious mistake — the text can still be copied underneath. This tool performs genuine redaction that removes the data entirely. It runs in-browser, so sensitive documents are never uploaded to third-party servers. For a detailed walkthrough, see our step-by-step guide.
Frequently Asked Questions
How is this different from drawing a black rectangle?+
Drawing black rectangles on a PDF is a common mistake — the underlying text remains in the file and can be recovered by copying, selecting, or running OCR. This tool rasterizes each page into an image after applying your redactions, so the redacted content is permanently gone.
Will the redacted text be recoverable?+
No. After redaction, the PDF is rebuilt page-by-page as flattened images. Text under the redaction boxes is rendered black and cannot be selected, copied, or re-extracted. Metadata is also stripped.
Are my documents uploaded?+
No. All redaction is performed in your browser. The PDF never leaves your device.
Will the PDF stay searchable after redaction?+
No — because this tool renders pages as images to guarantee permanent redaction. If you need a searchable result with redactions baked in, use the PDF OCR tool on the redacted file afterward.
How is this different from black-rectangle redaction?+
A black rectangle drawn on top of text only HIDES it visually — the underlying text remains selectable and copyable. True redaction removes the text from the content stream, replacing it with a solid block, so no amount of copying or text-extraction reveals the original.
What about redacting metadata?+
The tool includes a metadata-scrub option that removes author, title, keywords, comments, and XMP custom fields in addition to visible text. Hidden text layers (off-page objects, OCR layers) are also stripped.
Can I search-and-redact every instance of a word?+
Yes. Type a term, name, or pattern — the tool highlights every occurrence across the document. Confirm the matches you want redacted before export; partial-word matches can be toggled off for precision.
Is the redaction reversible?+
No — that’s the point. Once exported, the redacted content is permanently absent from the file. Keep an original copy elsewhere if you may need to refer back.

True redaction destroys the underlying text — not just paints a black box over the rendered page. The text layer at the redacted region is removed from the PDF's content stream, and any embedded images covering that region are clipped and re-encoded. This is the same approach U.S. federal agencies use for FOIA releases, and the only reliable defense against copy-paste extraction or layer-toggle reveals — common failure modes when redaction is done with highlighter tools.
