Redact PDF
To redact a PDF, upload the file and draw boxes over the names, ID numbers, or account details you need removed. Redaction covers and flattens the content so it cannot be recovered by copy-paste — unlike drawing a black box in an editor. It runs entirely in your browser.

Asked
Questions
Quick answers about this PurePDF workflow.
Is the PDF redaction tool free?
Yes. Redacting sensitive information is completely free.
Do my files get uploaded to a server?
No. Redaction runs entirely in your browser — critical for the sensitive documents this tool is made for.
Is the redacted content really removed?
Yes. Redaction covers the selected areas and flattens the result so the underlying content is not recoverable by copy-paste.
What should I redact?
Names, ID numbers, account numbers, addresses, and any personal data before sharing documents externally.
Can I redact multiple areas and pages?
Yes. Draw as many redaction boxes as needed across any number of pages before exporting.
How is this different from just drawing a black box?
A drawn box in an editor leaves the text underneath selectable. Redaction removes it — always verify by trying to select text in the exported file.
