Redact PDF

Permanently hide sensitive information. Unlike simply drawing a black box in a viewer, this removes the underlying text so it can't be recovered by copying or extracting it. It's completely free, with no account needed.

Features

True removal

the text under the black area is removed, not just hidden.

Secure

processed securely, with automatic deletion after processing.

Multi-area, multi-page

redact as many areas as needed, on every page.

Why redact instead of covering text?

Drawing a black rectangle over text doesn't always remove the original information. In many PDF viewers, hidden text can still be copied, searched, or extracted. Proper redaction permanently removes the underlying content before the file is shared.

Common use cases

Removing personal information before sharing a document publicly
Hiding sensitive figures in a shared financial report
Blacking out account or ID numbers before sending a scanned document

Documents commonly redacted

Legal documents
Contracts
Invoices
Medical forms
Identity documents

Your files are handled securely

Your document is used only to generate the redacted file, then removed from our servers right after processing.

Frequently asked questions

Is the hidden text really removed?

Yes. The page containing the redaction is converted to an image, so the hidden text no longer exists in the PDF and can't be copied or extracted.

Are non-redacted pages changed?

No, pages without a black area are kept as-is (selectable text preserved).

Can I redact several areas?

Yes, draw as many rectangles as needed, on as many pages as you want.

Do I need to install anything?

No, it works directly in your browser.

Is it free?

Yes, with no account required.

Can I redact a PDF on mobile?

Yes, the tool works on mobile browsers.

Can I undo a redaction?

No. Once the redacted PDF has been generated, the removed content can't be recovered — keep the original file if you may need it later.

Will the redacted page still contain selectable text?

No. The entire page containing a redaction is converted to an image, not just the blacked-out area, so its text is no longer selectable or searchable.
