Redact PDF

Redact a W-9 without uploading it.

A W-9 exists to carry a taxpayer ID, so a filled one holds an SSN or EIN, a signature, and an address: exactly what you do not want loose when you share a copy or store it. Whether you are passing along a sample or cleaning up the forms you collect from vendors, KeptPDF removes what you choose and permanently destroys the text, all in your browser. The original never leaves your device. Review the result before you share it.

A box over the SSN still leaves it in the file.

Most PDF tools redact by drawing a rectangle on top. On a W-9 that means the taxpayer ID, the signature, and the address stay in the file underneath, recoverable by moving the box or copying the text. The taxpayer ID is the one number you most need gone before a W-9 goes anywhere it should not.

The difference in one sentence

Real redaction destroys the taxpayer ID in the form, so a covered SSN or EIN cannot be recovered.

KeptPDF flattens each redacted page so nothing survives under the box, and it works in your browser, so the original form is never uploaded to a server. You can verify it yourself in the network tab.

A black box

A filled rectangle just sits on top of the text. Move it, switch viewers, or copy the page, and the hidden content is back.

KeptPDF

The page is flattened to an image, so the text underneath is destroyed. There is nothing left to uncover.

Covering text is not removing it. Give the result a quick review before you share it.

What a filled W-9 puts at risk

Auto-detect surfaces the structured identifiers, so a copy you share or file does not carry a live taxpayer ID.

SSN and EIN

The Social Security number or Employer Identification Number, the whole reason a W-9 is sensitive, is flagged for your review.

Name, business name, and address

The legal name, business name, and address on the form are surfaced so you decide how much identity to keep on the copy.

Signature and date

The signature and date are a judgment call. Box them and they are permanently removed, not just covered.

Signed or scanned copies

If the W-9 was printed, signed, and scanned, KeptPDF runs OCR first so it can find and redact text inside the image.

How to redact a W-9

Three steps, entirely on your device. Permanent, verifiable, no upload.

1

Open your form

Drop your file onto the page or pick it from your device. It loads into your browser, and nothing is sent anywhere.

2

Mark what to redact

Auto-detect finds names, dates, Social Security numbers, account numbers, and more. Draw boxes over anything else you want gone.

3

Download the clean copy

Save it. The marked content is permanently gone: the page is flattened to an image, not hidden behind a box. Give the result a quick review before you share it.

Permanent removal, nothing uploaded.

True text destruction

Each redacted page is flattened to an image, so the text layer is gone, not just covered with a shape. Content under a redaction box cannot be copied, selected, or recovered. Review the result before you share it.

Auto-detect the obvious stuff

One pass finds names, dates, phone numbers, Social Security numbers, addresses, and emails across the whole form, so you are not hunting for each one by hand.

Never uploaded

There is no upload step. The form is processed entirely in your browser, so the original is never part of a network request and never sits on anyone else's server.

Redaction certificate (Pro)

Pro adds a signed PDF and JSON audit record listing every redacted span, category, and page, which is handy for productions and compliance files. Anyone you send it to can re-check the fingerprint in their own browser, with nothing uploaded.

For everyone who sends or collects a W-9

Freelancers and contractors sharing a sample, and the accounting and AP teams who collect W-9s from vendors and need them clean before they go any further.

Questions, answered.

Does a black box remove the SSN from a W-9?
Not with most tools. The number stays in the file under the box and reappears if it is moved or the text is copied. KeptPDF flattens the page so the number underneath is destroyed.
Can I share a W-9 as a sample without a real taxpayer ID?
Yes. You control each box, so you can keep the layout and remove the SSN or EIN, the signature, and the address. Review the form before you share it.
Does it work on a signed, scanned W-9?
Yes. KeptPDF OCRs image-only pages before redacting, so it can find and permanently remove text that exists only as part of a scan.
Is it free, and is the form uploaded?
It is free with no account, and the form is processed in your browser, so nothing is uploaded. Pro ($29/month) adds a signed redaction certificate.
