QR Code Free is an independent website operated by Romero Melo. It brings together a browser-based QR generator and practical guides about creating, testing and printing QR codes.
What the tool provides
The generator creates static codes for website addresses or text, Wi-Fi credentials, contact details and email drafts. It exports PNG and SVG. It does not host your documents, provide an editable redirect account or offer scan analytics.
A static code stores its payload in the pattern. If that information changes, you need a new image unless you can maintain the same destination URL. A readable code also depends on the final design, size, material, camera and viewing conditions.
How to use the guides
The QR code guides explain practical issues such as quiet zones, contrast, file formats and payload structure. Worked calculations are examples rather than universal guarantees. Technical specifications are linked where relevant, and you should test the final exported file in its intended setting.
Data and third-party services
The QR image is generated in the browser. Remember that anyone who receives the image may read its encoded data. The website also uses hosting, analytics and other services described in the privacy policy. Read that policy for the website’s data practices.
Questions and corrections
For support or to report an error, use the contact page or email contato@romeromelo.com.br. Describe the device, browser, file format and steps needed to reproduce the issue. Use a synthetic example rather than sending passwords or private contact records.
