Convert MRZ Formats Instantly – TD1, TD2, TD3, MRV-A & MRV-B
Transform any MRZ code between passport, ID card, and visa formats in seconds. Built for developers, QA teams, and security researchers who need ICAO 9303 compliant test data.
Built for Real Workflows
For QA Engineers
Generate comprehensive test suites covering all document types. Upload one MRZ, get five format variations – perfect for regression testing and edge case validation.
For Developers
Integrate via API or use our web interface during development. Quickly verify your MRZ processing logic handles every ICAO format correctly.
For Security Researchers
Create controlled test scenarios with format-specific data. Safely test system boundaries without touching real identity documents.
Convert MRZ Formats in Three Simple Steps
Input Your Source MRZ
Paste an existing MRZ code or enter structured fields (name, document number, dates). Supports TD1, TD2, TD3, MRV-A, and MRV-B as inputs.
Select Target Format
Choose which ICAO format you need. Convert passport MRZ (TD3) to ID card format (TD1), or transform any combination – our engine handles field mapping automatically.
Get Validated Output
Download your converted MRZ with guaranteed compliance. Check digits recalculated, fields properly aligned, and structure validated against ICAO 9303.

Frequently Asked Questions
What MRZ formats can I convert between?
Our MRZ format converter supports all five ICAO 9303 document types: TD1, TD2, TD3, MRV-A, MRV-B. Convert from any format to any other format with full field mapping.
How do you handle fields that don't exist in the target format?
When converting to a shorter format, we intelligently truncate or wrap fields following ICAO guidelines. Optional fields may be omitted if space doesn't permit.
Is my data safe? Do you store uploaded MRZ codes?
Absolutely safe. All MRZ code conversion happens client-side in your browser. We never transmit, store, or log your input data.
Can I use this for production identity verification?
No. The tool is designed for testing, development, and educational purposes. Never use converted MRZ codes with real identity systems or in production environments.
