Redact PDF Content is a free, browser-based tool for covering sensitive text or images with a solid block before sharing a document. Important: this draws a visual cover over the content — the underlying text remains in the file's text layer and can potentially still be extracted by copy-pasting or text-extraction tools. For legally or security-sensitive redaction, use software that actually removes the underlying content.
How to use the Redact PDF Content
- Upload your PDF.
- Enter the page number and the box position/size as percentages of the page.
- Download the PDF with the black box applied.
- For genuinely sensitive documents, verify the underlying text isn't still selectable/extractable before sharing.

Frequently asked questions
Does this actually delete the covered text?
No — it draws an opaque shape over it visually. The underlying text/image content is not removed from the file.
How do I know if my redaction is secure enough?
Open the output PDF and try to select/copy the text under the black box — if it copies, the content is still present and this method isn't sufficient for sensitive use cases.
Is this tool free to use?
Yes, completely free on FreeToolsNets, with no sign-up and no limits.
Is my data sent to a server?
No. Everything runs locally in your browser using JavaScript — nothing you enter is uploaded anywhere.
Does it work on mobile?
