Free PII Redaction Tool for Text & JSON

Instantly remove or mask emails, phone numbers, IP addresses, SSNs, and credit card numbers from text or JSON. Ideal for logs, payloads, and LLM prompts.

🔒 No signup · No API key · No data retention · Requests processed in memory

This is a free PII redaction tool. No account required.

What Types of PII Can This Tool Redact?

• Email addresses
• Phone numbers
• IP addresses (IPv4 and IPv6)
• Social Security Numbers (SSNs)
• Credit card numbers

This free PII redaction tool is commonly used to remove personal data before storing logs, debugging JSON payloads, or sending data to third-party APIs and LLMs.

Common Use Cases for Free PII Redaction

• Sanitize application logs before sending to Datadog or Splunk
• Remove PII from JSON payloads used in debugging
• Sanitize LLM prompts before sending data to OpenAI
• Meet GDPR, SOC 2, and HIPAA privacy requirements

What Is PII Redaction?

Personally Identifiable Information (PII) includes emails, phone numbers, IP addresses, government IDs, and other data that can identify an individual. PII redaction replaces sensitive values before data is stored, shared, logged, or sent to third-party services.

Free PII redaction tools like this one are often used to test workflows before integrating a production API.

Why This Is Not an AI-Based PII Redaction Tool

This playground uses deterministic PII detection rather than probabilistic AI models. The same input always produces the same redacted output, with no hallucinations or missed entities.

This approach is preferred for compliance, audits, and production pipelines where predictability matters.

Need This in Your Application?

This free tool uses the same deterministic redaction engine as the Maskify API. Learn about the Maskify PII redaction API →

Redact PII from JSON Payloads

Use this free tool to redact PII from JSON payloads before logging, debugging, or sending data to third-party services.

Sanitize Logs for GDPR, SOC 2, and HIPAA

Application logs frequently leak emails, IPs, and identifiers. Maskify helps teams sanitize logs before sending them to tools like Datadog, Splunk, or ELK, supporting GDPR and privacy-by-design principles.

Is This Free PII Redaction Tool Really Free?

Yes. This playground is completely free to use with no signup or API key required. It is intended for testing and evaluating PII redaction before using the Maskify API in production.

How This API Playground Works

This playground sends your input to a sandboxed Maskify API endpoint using a restricted demo configuration. The response reflects the same redaction logic used in production environments.

Is This Safe?

This playground runs in a sandboxed environment with strict rate limits. Requests are processed in-memory and never written to disk or logs. Inputs are discarded immediately after redaction.
