Black Out Text in a PDF (Free)
'Blacking out' text in a PDF sounds simple, but there is a catch most tools never tell you: drawing a black rectangle leaves the original words sitting in the file. Select over the box, or open the PDF in another program, and the 'hidden' text reappears — countless leaks have happened exactly this way. PdfXpo blacks out text the right way: it deletes the underlying characters and image data, so what you remove is genuinely, permanently gone.
It is also completely private. Many free editors quietly upload your document to their servers to process it; PdfXpo never does. The whole operation runs in your browser with WebAssembly, so the file stays on your computer from start to finish. No account, no watermark, no limit — just mark what you want gone, remove it, and download a clean PDF in seconds.

How to Black Out Text in a PDF (Free) — Step by Step
1. Open the free Redact PDF tool at PdfXpo.com — no account, no email, nothing to install. The tool loads entirely in your browser, so your file never gets uploaded to a server. Drag your file straight in and it is ready to work on in seconds.
2. Draw a box over every piece of sensitive information you need gone — names, numbers, addresses, signatures, whole regions of a page. You can mark as many areas across as many pages as you like; there is no daily limit and no watermark on the result.
3. Run the redaction. PdfXpo physically deletes the underlying text and image data inside the file — not just a black box on top — so the information cannot be copied, searched, or recovered. Download your clean, court-and-compliance-ready PDF instantly.
Why PdfXpo for Redaction
PdfXpo is the safest free way to black out text because it removes the words instead of merely hiding them, and it never uploads your file. You get a clean, watermark-free PDF that opens anywhere, and you can prove the privacy yourself by checking that no network request carries your document.
Common Questions
If I black out text, can people still read it?
With most tools, yes — the text survives under the box. With PdfXpo, no: we delete the underlying text so it cannot be selected, copied, or recovered.
Is my PDF uploaded to black out text?
No. PdfXpo works entirely in your browser, so your file never leaves your device.
Can I black out images or whole sections, not just text?
Yes. Draw a box over any region — text, images, signatures, or an entire area — and its data is permanently removed.
Is it free with no watermark?
Yes. It is free and unlimited, and the result has no watermark and needs no account.
