Free PII Redaction Tool

PII redaction is the process of identifying and removing personally identifiable information (PII) from documents. This includes data like Social Security numbers, phone numbers, email addresses, credit card numbers, names, and physical addresses. Redaction ensures sensitive information is permanently hidden before documents are shared, published, or archived.

Our free PII redaction tool automatically detects Social Security numbers (SSNs), phone numbers, email addresses, credit card numbers, dates of birth, physical addresses, and personal names. You can toggle individual pattern categories on or off and add custom words or phrases to redact.

The PII redactor currently supports PDF (.pdf) and Microsoft Word (.docx) files. Upload your document and receive a redacted version in the same format with all detected PII removed.

Yes. Your documents are processed securely and are not stored on our servers. Files are uploaded temporarily for processing and are automatically deleted immediately after redaction is complete. No document content is logged or retained.

Yes, this PII redaction tool is completely free to use with no sign-up required. There are no usage limits, no watermarks on output files, and no hidden fees. We built it because we needed it ourselves and wanted to share it with the community.

The tool uses pattern matching and entity recognition to detect common PII formats with high accuracy. For best results, we recommend reviewing the redacted output before sharing. You can also add custom words or phrases to catch organization-specific terms or names that automated detection might miss.

Yes. Before uploading your document, you can toggle individual detection categories on or off — for example, redact emails and SSNs but leave phone numbers visible. You can also add a custom list of words or phrases that should always be redacted.

PII redaction permanently removes sensitive information from a document, replacing it with black bars or placeholder text so the original data cannot be recovered. Data masking typically replaces data with realistic but fake values and is often reversible. Redaction is the preferred method when documents will be shared externally or made public.

PII redaction is essential for anyone uploading documents to AI services like ChatGPT or Claude, legal professionals handling case files, healthcare organizations managing patient records, HR departments processing employee documents, financial institutions sharing reports, government agencies responding to FOIA requests, and any business that needs to share documents while protecting personal information.

While this tool helps you redact personal information from documents — a key step in data protection — compliance with regulations like GDPR, HIPAA, and CCPA involves broader organizational policies and practices. We recommend consulting with a compliance professional to ensure your full workflow meets regulatory requirements.

Yes — this is one of the most common use cases for our PII redaction tool. When you upload documents to AI services like ChatGPT, Claude, Gemini, or Copilot, any personal information in those files may be processed or stored by the AI provider. Redacting PII before uploading ensures that sensitive data like names, Social Security numbers, and contact information never reaches the AI service in the first place.

AI services like ChatGPT and Claude may use uploaded content for model training, store it on their servers, or expose it through data breaches. Even if a provider claims not to train on your data, redacting PII before uploading is a best practice because it eliminates the risk entirely. This is especially important for businesses handling client data, legal documents, medical records, or financial information — where accidental exposure of personal data could violate privacy regulations or breach client trust.

Any document containing personal information should be redacted before uploading to AI tools. Common examples include contracts and legal agreements with client names and addresses, HR documents with employee SSNs and salary data, medical records and patient intake forms, financial statements and tax documents, customer support logs and CRM exports, and any internal documents with employee or customer contact information.
