Redact PDF
Permanently cover up text or graphics containing sensitive information.
How to redact information in a PDF online
Upload the PDF to redact
Drag your file or click to select it from your computer.
Draw boxes over what you want to hide
Use your mouse to mark each area of text or image you want to permanently cover, across as many pages as you need.
Apply the redaction and download
The page is turned into an image with the areas already blacked out, so the hidden content can't be recovered or copied.
Why redact your PDFs in PDFDocks?
Covering up confidential information in a PDF — account numbers, personal data, specific clauses — before sharing it with someone is exactly the kind of task that shouldn't require uploading that same sensitive document to an external server. In PDFDocks, redaction is done with JavaScript, directly in your browser: the file never leaves your device. It's important you understand how it works technically: the tool converts the entire page into an image with the marked areas already struck through in black permanently. This is key to the real security of the process, because it means the hidden text doesn't remain "underneath" a black rectangle (as happens if you simply draw a box in a regular PDF editor, where the text is still there and can be copied or recovered) — once flattened to an image, the covered content truly disappears.
Is redaction permanent?
+
Yes. Your file is never uploaded to a server: redaction is performed directly in your browser with JavaScript, so the PDF never leaves your computer at any moment.
Can redacted text be recovered or copied afterwards?
+
No. The page is converted into an image with the redacted areas permanently blacked out, so the hidden content cannot be recovered or copied.
Is my PDF uploaded to a server when using this tool?
+
No. The entire redaction process happens in your own browser, without your file traveling over the internet.
Is my PDF private?
+
Yes, no installation required. It works directly from your browser, with no account creation or additional software downloads needed.
Is the text on the redacted page still selectable?
+
Text redaction works on text. For images, use crop or other tools instead.
Do I need special software?
+
Yes, you can mark as many areas as you need on each page before applying the redaction.
