How to Redact a PDF on Windows

To redact a PDF on Windows without Adobe Acrobat Pro, open it in InkOut PDF below in Edge or Chrome, drag a box over each thing you want removed, then export. The content under each box is deleted from the file, not just covered, and the exported file is checked before you can download it. Nothing is uploaded, and files up to 5 pages are free.

Adobe Acrobat Pro, Premium or StudioYes, with the Redact toolAdobe says redaction is available only in those editions, not the free Acrobat Reader (Adobe). See how to redact in Adobe Acrobat
Microsoft Edge's built-in PDF readerNot listed by MicrosoftMicrosoft's documentation of the Edge PDF reader lists viewing and printing, basic form filling, inking, highlighting, text notes and read aloud (Microsoft Learn). It doesn't list a redaction tool

Microsoft's Edge page describes the reader as letting you "highlight, mark up, add text, and save your changes" (Microsoft). Marking up is not the same as redacting. If you blacked out something with a pen or highlighter in any PDF reader, test the saved copy as described below before you share it. We didn't test Edge's own tools for this page, because our test machine doesn't run Windows.

Why drawing over text isn't redaction: our test

We made a 1-page PDF with an account number and a Social Security number, then covered each one with a black mark of the kind drawing and shape tools add: a black-filled rectangle over the account number and a thick black line over the SSN. On screen both numbers were completely hidden. But copying the text out of the file (with pdftotext) still returned "Account number: 1234-5678-9012" and "SSN: 123-45-6789", and InkOut PDF's free redaction checker flagged the page:

InkOut PDF's redaction checker reporting a leak: text is still hidden under black boxes on page 1

The U.S. District Court for the District of New Jersey gives filers the same warning: "highlighting text in black or using a black box over the data in MS Word or Adobe Acrobat will not protect the data from being able to be seen" (source).

We then opened the same file in InkOut PDF, drew two boxes over the covered numbers and exported. All six automatic checks passed, the exported file had no annotations and no extractable text left on the page, the title and author were empty, and running it through the checker again gave "No hidden text found under black boxes". The file went from 1,369 bytes to 21,784 bytes, because the redacted page is now an image.

How to redact a PDF on Windows in your browser

  1. Open this page in Edge or Chrome and click Choose PDF above. The file opens in the browser tab and isn't uploaded.
  2. Drag on the page to draw a box over each thing you want removed. Drag a box to move it; to remove one, tap or click it, then tap ×.
  3. Click Apply redaction(s). Each page with a box is rebuilt as an image with the box burned in, and the document metadata is left out.
  4. Read the automatic check, then click Download redacted PDF. Your original file isn't changed.

Check the saved file on Windows

Open the downloaded PDF, press Ctrl+F and search for part of what you removed, such as the last 4 digits of an account number. Then try to select and copy the area under a box. If either finds the text, the redaction failed. You can also drop any PDF into the free redaction checker.

What we tested, and what we didn't

We tested the live tool on October 22, 2026 (PT) in Google Chrome 155 on Linux, and again in Chrome's iPhone 13 device emulation with touch input (not a real iPhone). The tool is a web page, but we haven't run it in Edge or on a Windows PC. If anything looks wrong on your machine, the automatic check after export is still the thing to trust: the download stays disabled if a check fails.
