Redact a PDF online

Redacting a PDF online lets you hide confidential parts of a document — personal data, pricing, internal notes — without installing specialist software, straight from your browser. Open the file, draw a redaction box over each item that needs to be concealed, and the tool blacks those areas out in the version you download. Online redaction is convenient when you are on a machine where you cannot add software, or you just need a quick way to sanitise a document before forwarding it. Because redaction exists precisely to protect sensitive information, where the work happens matters: this tool processes everything inside your browser, so the original, unredacted document is never sent to a server or stored anywhere. Cover every sensitive item across all pages, download the cleaned copy, and review it carefully before sharing to be sure the redactions are complete and correctly placed. Your source file stays untouched on your device.

Frequently asked questions

Do I need to install anything to redact online?
No. It runs in the browser, so there is nothing to download — useful on a managed or shared computer.
Is my document uploaded to redact it?
No. Redaction happens on your device, so the unredacted file never leaves your browser.
