Redact PDF Content Online

Cover selected page regions and rebuild each redacted page as a flattened image-based page.

Quick answer

What does Redact PDF do?

Cover selected page regions and rebuild each redacted page as a flattened image-based page. The selected PDF is processed locally in this browser without being sent to a backend conversion server. The rectangle is set with percentage controls rather than automatic text detection, so careful visual review is essential.

Use Redact PDF when you need to remove visible content from selected page regions. Common uses include remove an account number from a shared page, cover a name or address in a scan, create a flattened review copy with selected visible content removed.

Designed around the task

Why use Redact PDF?

Focused controls, local processing, and clear limits help you finish the job without sending the document to a conversion server.

Focused results

Renders selected pages, applies the redaction block to the pixels, and rebuilds those pages as images.

Useful browser controls

Private by design

The selected PDF is processed by JavaScript running in this browser for Redact PDF. NoLogPDF does not send it to a backend conversion API, and file names, contents, form values, passwords, and output data are excluded from site analytics.

Automatic file recognition

NoLogPDF checks the selected file in your browser and shows the controls available for Redact PDF.
