Redact PDF Online

Direct answer

Real redaction: text destroyed, not covered — then you review output previews and a remaining-text check. Zero extracted matches alone cannot prove safe redaction. All of it in this browser tab.

Your file never leaves this tab. No upload, no account, no signup, no email, no watermark — download the result the moment it's ready.

Honest limits

What Redact Text Does — and What It Refuses

The documents this tool will not touch, and the ten-second checks to run before you send the result.

Works on

What this tool handles reliably.

  • Destroys matched text for real: the page is rebuilt as an image, so the bytes are gone.
  • Scans the text layer for personal-data patterns, and takes your own terms as well.
  • Re-scans extractable text for each term; the result is not a visual or forensic certificate.

Refuses on purpose

Not bugs — decisions we made and will state.

  • To automatically recognize every sensitive pixel: scan regions, signatures and stamps must be marked with visual boxes and reviewed.
  • To keep the text layer: a redacted page becomes an image, so it is no longer selectable or searchable.
  • To fix the original. The redaction lands in the exported copy you choose to send.

Check afterwards

The ten seconds we ask you to spend.

  • Search the output for every term yourself — the report should agree with you.
  • Zoom in on the redacted regions to confirm nothing shows through.
  • Check whether losing selectable text breaks a downstream step in your workflow.

Written for Redact Text specifically. If your file is on the refuses list, the page you need is the tool that handles it — not this one with the limits removed.

Step by step

How to Redact PDF Online in 3 Easy Steps

Browser-local document processing with no application installation required.

1

Drop the PDF

Add a PDF up to 120 pages / 50 MB. Text is scanned for patterns; scans can be redacted with visual boxes.

2

Pick the Occurrences

Select text matches or draw boxes on page previews. Check every page for repeated sensitive content.

3

Redact, Verify, Download

Rebuild matched pages and review the text-layer check. Download and inspect all sensitive regions visually; zero extracted matches alone does not prove safe redaction.

🔎

Find Text or Draw Boxes

Find personal-data patterns and custom terms, or draw page-specific boxes over scan pixels, stamps and signatures.

🔥

True Removal, Not a Black Box

Matched pages are rebuilt as images with the text destroyed underneath — nothing left to select, copy or extract.

✅

Review Before Download

Review every output preview and the remaining-text check. Zero extracted matches alone cannot prove safe redaction.

Stays On Your Device

Redaction usually involves the most sensitive documents you own. The whole process runs in this browser tab.

FAQ

Frequently Asked Questions

Get clear answers about data flow, formatting, integrity, and usage limits.

Which PDFs are supported?
Use a PDF up to 120 pages / 50 MB. Draw visual boxes on scans or search readable text and ordinary text/choice/checkbox/radio form values. Common drawn annotations with valid appearances are supported. Selecting an annotation/field match covers its whole rectangle. Annotation-bearing pages become images and links lose interactivity. XFA, password/rich-text fields, attachments/media annotations, hidden or unrenderable content, signed/encrypted files and oversized files are refused. Cumulative 80 MB PNG and 40-megapixel raster working budgets may also stop a large job; no partial download is created.
How do I redact a PDF for free?
Add a PDF with extractable text, review detected matches and add your own search terms. Select the occurrences to remove, create the redacted copy and inspect it before sharing. No account, signup or email is required and no document upload is needed; you download the redacted copy the moment it's ready. For content in images, open the visual box editor and mark every sensitive region yourself.
Can I redact a bank statement?
For a statement with extractable text, you can target approved account details or other terms. Confirm what the recipient requires before removing anything. Check every page and image visually; repeated numbers, scans and transaction images can escape text matching. Do not hide information required for an application or financial review.
Does a zero remaining-text count prove the PDF is safe to share?
No. The check searches extractable text, not every visible pixel or hidden data location. Rebuilt image pages can contain no searchable text even if sensitive information is still visibly present elsewhere. Inspect the actual download, review metadata and attachments, and use an independent reviewer for high-stakes releases.
How do I properly redact text in a PDF?
Proper redaction destroys the text, not just its appearance. Drawing a black rectangle over words leaves them in the file — anyone can copy-paste or search them out. Here, every page with a selected match is rebuilt as an image with the match painted out at render time: the underlying text object no longer exists in the copy.
Is drawing a black box over text in a PDF safe?
Almost never. Unless the box is burnt into an image, the words under it stay extractable — this is one of the most common redaction failures in leaked documents. The pre-send checker can detect text sitting under black boxes; this tool removes the text instead.
How is the redaction verified?
After rebuilding, the tool searches the output’s extractable text for each term. This is a text-layer check, not a visual or forensic certificate. Independently inspect every redacted region and other sensitive locations in the exported file.
What happens to the redacted pages?
They become images (that is what makes the removal irreversible), so they lose selectable text. Pages with annotations or fields also become images so their visible appearances survive without live objects. Pages without matches or annotations retain searchable page content. The trade-off is stated before you run it.
Can it redact scanned documents?
Yes. Open the visual box editor, choose a page, zoom in and draw a rectangle over each sensitive area, or enter its position and size as percentages. Those pages are rasterized with the selected pixels painted black; this is not a live overlay. Boxes do not find repeated values on other pages. Inspect the full-size exported previews; there is no automatic OCR or pixel-safety certificate.
Is my document uploaded?
No. Scanning, redaction and verification all run in this browser tab. Redaction requests are exactly the documents you most need to keep local.
