About the Data Matrix Generator

Data Matrix packs a lot into a small square: up to 2,335 characters, and still readable when part of it is damaged. It is the code on electronic parts, medical devices (UDI) and pharmaceutical packs. Type text or switch to GS1 mode and add Application Identifiers (GTIN, batch, expiry, serial); the generator checks each field before it draws the code.

Frequently asked questions

What is the difference between Data Matrix and QR?
Both are 2D codes. Data Matrix is smaller for the same data and is the standard for industrial and healthcare marking; QR is what phone cameras open by default.
Is anything I type or scan uploaded?
No. Codes are drawn and read inside your browser (bwip-js and the ZXing reader, compiled to WebAssembly); nothing you type, upload or point the camera at reaches our servers.
Can I make codes from a script, a spreadsheet or an AI agent?
Yes, with no account. https://openvibe.tools/api/codes/qrcode.svg?text=Hello is the image itself (any symbology, .svg or .png; /api/codes lists them), so it works in an <img> tag or Markdown. POST /api/v1/tools/<tool>/run answers JSON, and the OpenAPI document is at https://openvibe.tools/api/v1/openapi.json.
