What is the difference between Draw mode and Search mode?

Draw mode lets you visually select areas on a PDF page by clicking and dragging to create black rectangles. This is useful for redacting images, signatures, or irregular areas. Search mode lets you type a word or phrase, finds every occurrence across all pages, and redacts them all at once. This is ideal for names, account numbers, or email addresses that appear multiple times.

Is my PDF uploaded to a server when I redact it?

No. YourPDF.tools processes everything in your browser using JavaScript. Your PDF never leaves your device. There is no server upload, no cloud processing, and no third-party access to your files.

What types of content should I redact from a PDF?

Common content to redact includes: Social Security numbers, bank account and credit card numbers, personal names and addresses, email addresses, phone numbers, medical information, trade secrets, and any other personally identifiable information (PII) that should not be visible to the recipient.

How to Redact a PDF Online — Without Uploading Your Files

You have a PDF that contains sensitive information — a contract with Social Security numbers, a medical report with patient names, a financial statement with account details. You need to share the document, but certain parts must be hidden. The solution is to redact the PDF: permanently black out the confidential content so it cannot be seen, copied, or recovered.

Most online PDF redaction tools require you to upload your document to a remote server. For a document that already contains sensitive information, that defeats the purpose. YourPDF.tools does all redaction processing entirely in your browser. Your file never leaves your device — which is exactly how it should work when you are handling confidential data.

Key Takeaways

•Redaction permanently covers sensitive information with black rectangles — the content cannot be recovered.
•Two modes: Draw rectangles visually or search for text to redact automatically across all pages.
•Your file is processed 100% in your browser — nothing is uploaded to any server.
•No sign-up, no watermark, no daily limits — completely free.

Step-by-Step: How to Redact a PDF

The process takes under two minutes. Here is exactly what to do:

Open the Redact PDF tool. Navigate to yourpdf.tools/redact-pdf in any modern browser — Chrome, Firefox, Safari, or Edge all work.
Drop your PDF file into the upload area. You can drag the file directly from your file manager, or click the area to open a file picker. The file is read locally by your browser; nothing is transmitted over the network.
Choose your redaction mode. Use “Draw to Redact” to visually select areas by clicking and dragging on the page. Use “Search & Redact” to type a word or phrase and redact every occurrence automatically.
Draw or search to create redactions. In Draw mode, click and drag on the PDF page to create black rectangles over sensitive areas. In Search mode, enter your text, click “Find & Redact,” and all matches are added as redactions. You can use page navigation to move between pages and add redactions to any page.
Apply and download. When you are satisfied with all redactions, click “Apply Redactions & Download.” The tool creates a new PDF with black rectangles permanently drawn over the redacted areas, then downloads it to your device.

When Should You Redact a PDF?

Redaction is essential whenever you need to share a document that contains information the recipient should not see. Common scenarios include:

Legal documents: Contracts, court filings, and depositions often contain personal information about parties not involved in the current matter. Redact names, addresses, and identifying numbers before sharing.
Medical records: HIPAA requires that patient-identifying information be removed before sharing records with unauthorized parties. Redact patient names, dates of birth, medical record numbers, and other PHI.
Financial statements: Before sharing bank statements, tax returns, or invoices, redact account numbers, routing numbers, and Social Security numbers.
HR documents: Employee records, performance reviews, and salary information should be redacted before being shared outside the HR department.
Public records requests: Government agencies must redact personally identifiable information before releasing documents under FOIA or similar laws.

Draw Mode vs. Search Mode: Which to Use

Draw mode is best when you need to redact visual content — images, signatures, handwritten notes, or specific areas of a page that contain mixed content. You click and drag directly on the page preview to create rectangular redactions. This gives you precise control over exactly what gets covered.

Search mode is best when you need to find and redact specific text that appears multiple times across the document. Type a name, account number, or email address, and the tool finds every occurrence across all pages. One click redacts them all. This is faster and more thorough than manually drawing rectangles on every page.

You can use both modes on the same document. Start with Search mode to catch all instances of known sensitive text, then switch to Draw mode to cover any remaining visual content that needs redaction.

Pro Tips for PDF Redaction

Always keep the original. Redaction is permanent. Once you download the redacted file, the covered content cannot be recovered. Save a copy of the unredacted document in a secure location.
Review every page. Use the page navigation to check each page of your document. Sensitive information can appear in unexpected places — headers, footers, watermarks, or embedded form fields.
Remove metadata too. After redacting visible content, consider using the PDF Metadata tool to strip document properties (author name, creation date, software used) that might reveal information about the document's origin.
Combine with password protection. If you want an extra layer of security, use the Protect PDF tool to add a password to the redacted document.
Test with a copy first. If you are redacting a critical document for the first time, practice on a copy before working with the original. This lets you refine your approach without pressure.

Frequently Asked Questions

What does redacting a PDF mean?

Redacting a PDF means permanently removing or covering sensitive information. Our tool draws opaque black rectangles over the areas you select or the text you search for. The covered content cannot be selected, copied, or recovered from the saved file. This is different from simply changing text color to black or highlighting over text, which can often be reversed.

Can redacted content be recovered?

No. When you apply redactions with our tool, black rectangles are drawn directly onto the PDF page content. The resulting file does not contain the original text or images underneath the redaction marks. This is a permanent, irreversible operation. Always keep a copy of your original document if you might need the unredacted content later.

Is this tool HIPAA/GDPR compliant?

Because all processing happens entirely in your browser and your files are never uploaded to any server, there is no data transmission or third-party access involved. This client-side-only approach aligns well with the data minimization principles of GDPR and the security requirements of HIPAA. However, compliance depends on your overall workflow — always consult with your compliance team about your specific requirements.

Are my files uploaded to a server?

No. This is the core principle of YourPDF.tools. Your PDF is loaded into your browser's memory, processed using JavaScript, and the result is saved back to your device. The file never touches a remote server. You can verify this yourself by disconnecting from the internet after loading the page — the tool continues to work because no network connection is needed for processing.

Can I redact images and signatures, not just text?

Yes. Use Draw mode to place black rectangles over any visual content on the page — including images, signatures, stamps, logos, or any other graphical element. The redaction covers whatever is underneath it, regardless of whether it is text or an image.
