How to Redact Sensitive Information in a PDF

Last updated: February 22, 2026

Redacting a PDF means permanently removing sensitive information — not just covering it with a black box that someone can copy-paste from underneath. OneClickPDF performs true redaction: it draws the redaction areas, then rasterizes the entire page so the original text is physically destroyed. And it all happens in your browser.

Step-by-Step Guide

1

Open the Redact PDF tool

Go to the Redact PDF page on OneClickPDF.

2

Upload your document

Drop your PDF onto the upload zone. It loads in a full-page editor with zoom controls.

3

Mark areas for redaction

Use Draw mode to click-and-drag redaction rectangles over sensitive content. Or use Find Text mode to search for specific words or phrases across all pages — matches are highlighted and you can selectively add them to the redaction list.

4

Apply redactions and download

Review your pending redactions in the sidebar (grouped by page). Remove any you don't want. When ready, click Apply. The tool permanently destroys the redacted content by rasterizing every page at 2x resolution.

Frequently Asked Questions

Can redacted text be recovered?
No. OneClickPDF performs true redaction by rasterizing the entire page into a flat image. The original text data is completely destroyed — there is no hidden layer to extract.
What's the difference between redaction and covering text?
Many tools simply draw a black rectangle over text, but the text remains in the PDF's data layer and can be copied or extracted. True redaction (what OneClickPDF does) permanently removes the underlying data.
Can I redact a specific word across all pages?
Yes. The Find Text mode searches your entire document for a specific word or phrase, shows all matches, and lets you add them all to the redaction list at once.
Does my document go to any server?
No. The entire redaction process — text search, drawing, and rasterization — happens locally in your browser. Your sensitive document never leaves your device.

True redaction is irreversible by design. Unlike simply drawing a black box over text (which many 'redaction' tools do), OneClickPDF rasterizes the entire page, making it physically impossible to recover the hidden content. For legal documents, FOIA requests, and compliance, this is the standard you need.
