Black out sensitive text or images before sharing a PDF — for real. The redacted area is flattened into the page itself, not just covered with a box, so nothing underneath can be selected or copied out. Runs locally in your browser.
How to Use Redact PDF
- 1
Upload your PDF
Click the upload area or drag in the document with sensitive content.
- 2

Click any page in the thumbnail rail to see it — mark boxes on as many pages as the document needs.
- 3
Draw over what to hide
Drag over each area you want permanently blacked out — draw as many boxes as you need.
- 4
Redact and download
One click redacts every page you marked and downloads the result — nothing is uploaded first.
Why Choose PurePDF for Redact PDF
Nothing leaves your device
Redaction happens locally in your browser — the document is never uploaded.
Genuinely removed, not just covered
The redacted page is rebuilt as a flattened image, so the underlying text truly can't be recovered — unlike a simple black rectangle placed on top.
Common Use Cases for Redact PDF
Hide an ID or account number
Black out a social security number, account number, or other identifier before sharing.
Prepare a document for legal disclosure
Redact privileged or confidential sections before producing a document.
Share a form without private details
Hide a signature, address, or other personal field before forwarding a form.
Pro Tips for Redact PDF
- This tool redacts one page at a time — repeat it if you need to redact multiple pages.
- Because the redacted page becomes an image, its text is no longer searchable or selectable — this is intentional for real redaction.
- Double-check the downloaded file before sharing — redaction can't be undone once shared.
Frequently Asked Questions About Redact PDF
Will my PDF file be uploaded to a server?
No — nothing is uploaded. This tool runs entirely in your browser via WebAssembly/JavaScript; your file never leaves your device.
Is there a file-size limit, a usage cap, or a hidden fee?
It's free and unlimited, with no watermark and no forced file-size cap — the only real limit is your own device's memory for very large files.
Do I need to create an account or sign up?
No — no account, email, or sign-up is required for any tool. Just start using it.
Can I use this on my phone (iPhone or Android)?
Yes — it works in any modern mobile browser, no app install needed.
Can someone copy or reveal the text hidden beneath the black boxes?
No. The redacted page is rebuilt and flattened as an image, permanently removing the underlying text layer so it cannot be selected, copied, or uncovered.
Why is text on the redacted page no longer selectable or searchable?
To ensure irreversible privacy, redacted pages are flattened into raster images, which intentionally disables text search and selection on those specific pages.
