FAQ
How do I anonymize text for free online?
Paste your text into the tool: it automatically detects emails, phone numbers, IPs, IBANs and card numbers, then replaces them with masks. Everything runs in your browser, for free and without signing up.
Is text anonymization GDPR compliant?
Masking personal data is a key measure recommended by the GDPR. Because processing happens locally in your browser, no data is transmitted or stored, which greatly reduces privacy risks.
What is the difference between anonymization and pseudonymization?
Anonymization permanently removes the link to a person, whereas pseudonymization replaces data with a reversible identifier. This tool masks data to make it non-identifiable in the shared text.
