PDF Redactor – Free Online Tool
Redact sensitive information from PDFs locally with smart PII detection, manual boxes, flattened export, and copyable audit notes.
Free PDF Redactor With No Uploads
ToolsMint PDF Redactor helps you hide sensitive information in PDF files directly in your browser. Upload a PDF, scan for common private data, add manual redaction boxes, and download a redacted copy without sending the document to a server.
Redact Emails, SSNs, Phone Numbers, Cards, and API Keys
The smart scan checks selectable PDF text for high-risk patterns such as email addresses, US Social Security numbers, phone numbers, payment card numbers, and common API key formats. It creates reviewable boxes so you can confirm the redactions before export.
Flattened Redacted PDF Export
A black box over text is not enough if the original text remains selectable underneath. This tool renders each page, applies the redaction boxes, and exports a flattened PDF image layer so covered text is removed from the exported document surface.
Manual Redaction Boxes for Real Documents
Not every sensitive detail follows a predictable pattern. Click the page preview or use Add Box to cover names, addresses, account numbers, signatures, QR codes, barcodes, screenshots, notes, and other private areas.
Built for Everyday PDF Privacy Workflows
Use the PDF redaction tool before sharing contracts, invoices, HR forms, legal exhibits, financial records, support logs, school documents, research files, or client reports. The audit summary gives you a quick record of what was redacted.
Frequently Asked Questions
Everything you need to know about the PDF Redactor.
Is this PDF redactor free?
Yes. It is free to use with no signup, watermark, or account requirement.
Are my PDFs uploaded?
No. PDF loading, scanning, redaction preview, and export happen locally in your browser.
Does it permanently remove covered text?
The exported PDF is flattened into page images with redactions applied, so covered text is not left as selectable text behind the boxes.
Can it detect sensitive information automatically?
Yes. The smart scan looks for common emails, phone numbers, US SSNs, payment card numbers, and API key patterns in selectable PDF text.
Can I add manual redactions?
Yes. Click the page preview or use Add Box to cover names, addresses, signatures, account numbers, images, and any area the scan does not detect.
Will OCR work on scanned PDFs?
The smart scan needs selectable PDF text. For scanned pages, add manual redaction boxes over the visible areas you want to hide.
