Privacy-First PII Redactor – Remove Personal Data Locally
Redact emails, phone numbers, URLs, IP addresses and common API keys from text before sharing it online. This free privacy tool runs locally in your browser, requires no account, and does not upload your text.
What this tool does
This PII Redactor helps remove or mask common personal identifiers from text before you share it for support, feedback, documentation, or analysis. Select the categories that match your material, run the existing redaction action, and review the output rather than assuming every sensitive value was detected.
What counts as personal information
Personal information can include names, email addresses, telephone numbers, account identifiers, addresses, dates of birth, government numbers, payment details, access tokens, and private URLs. Context matters: a value that looks harmless on its own may identify someone when combined with a location, employer, order number, or unique event.

Contact [NAME] at [EMAIL] or [PHONE] about order [ID]. Always compare the output with the original and remove any remaining clues manually.Practical uses
Use the tool before posting bug reports, sharing screenshots as text, preparing a training example, sending a support ticket, or asking a colleague to review a document. Preserve only the minimum context needed to solve the problem, and use synthetic examples instead of real customer or employee data whenever possible.
Limits and privacy
Automated redaction is a convenience, not a guarantee of anonymity. It may miss names, custom identifiers, images, handwriting, encoded values, secrets, or sensitive facts that require human judgment. Processing is performed in the browser, but the original and redacted text can remain in the page, clipboard, browser history, screenshots, or device memory; do not paste highly confidential data into a shared or untrusted device, and verify the final copy before publishing.
What Is PII?
PII means personally identifiable information: data that can identify, contact, locate, or authenticate a person. Common examples include email addresses, phone numbers, IP addresses, URLs containing private tokens, and API keys. Removing this information before sharing a log, support ticket, prompt, or code sample can reduce accidental exposure.
How This Free Redactor Works
ToolMixo scans the text in your browser for selected patterns and replaces matches with clear labels. It keeps the rest of the text and line breaks in place, making the result useful for debugging, documentation, AI prompts, customer support, and public examples.

When Should You Redact Personal Data?
Use the redactor before publishing screenshots, copying error logs into a forum, sending prompts to an AI service, sharing customer-support examples, or posting code snippets. It is especially useful for developers, support teams, students, researchers, and content creators who regularly share text from real projects.
Frequently Asked Questions
Does this tool upload or store my text?
No. The current tool uses JavaScript in your browser and does not send the text to a server or AI API. Your browser may still retain normal page data according to your own browser settings, so clear the page if you are working with highly sensitive material.
Can it find every personal detail?
No. It detects selected patterns such as emails, phones, URLs, IP addresses and common API-key formats. Names, addresses, unusual identifiers and context-specific secrets may require manual review.
Can I use the result in an AI prompt?
Yes, but review the redacted text first. Removing an email or phone number does not automatically remove every confidential business detail, name, code fragment, or unique combination of facts.
Does it support Arabic and other languages?
Yes. The tool preserves Unicode text and can process Arabic, English and other languages. The built-in detectors focus on patterns such as email and phone numbers rather than one specific language.
