What should someone see when they scan?
Use the complete address, including https://. No link shortening or redirects are added.
Opens a draft in a compatible email app. This tool never sends email.
Include the country code for international use. Extensions are not supported.
SMS message handling varies by phone and scanner. Test it before sharing.

Add your logo optional
Centered when it's safe for your content, or placed just below the code when it isn't.
Maximum 2,048 × 2,048 pixels
Your image is read locally, not uploaded. SVG, GIF, WebP and animated PNG files are not accepted. The logo sits below the QR, outside its clear border.
Data stays black.
High error correction.
Logo centers when possible.
Only the 3 corner squares change color.
All other data stays black for reliable scanning.
Up to 1,000 UTF-8 bytes per code. No generation quota, fees, or watermark.
Your browser does the work.
No QR-generation API, logo upload, saved history, or third-party scripts.
No middleman in your QR.
Your content is encoded directly. No Carmedin redirects, scan analytics, or imposed expiry.
Download. Test. Share.
Create as many codes as you need. The destination itself can still change or become unavailable.
A few things worth knowing.
What stays private?
This tool processes entered content and selected logos in your browser. It does not transmit them to Carmedin or third parties, or deliberately save a generation history. Downloads are saved to your device.
Ordinary website access and security logs may still be collected. Your browser, extensions, device backups, and files you share are outside this tool's control. Read Carmedin's Privacy Policy.
Why does my logo sometimes appear below the code instead of centered?
Your logo is centered on top of the QR whenever that's safe for your specific content, with a protective white area behind it and the code's own error correction covering the rest. For some longer content (typically longer Wi-Fi credentials or contact cards), the QR's structural pattern leaves no safe spot near the center at any size, so the logo is placed in its own space just below the code instead. Either way, the underlying QR payload is verified locally before export.
Can I change a QR after downloading it?
These are static codes. Their contents cannot be changed after export. Generate a new image when the encoded text or address changes. Carmedin does not impose an expiration date, but a linked destination may change, require a login, or go offline.
What should I avoid encoding?
Do not encode patient information, private access tokens, confidential records, or internal-network credentials. A QR code is not encryption. Anyone who obtains the image may read it. Only include information and logos you have permission to distribute.
Terms and responsible use
Use this tool lawfully. Do not use it for fraud, phishing, impersonation, or infringement. You are responsible for your content, your rights to any logo, and testing the result. Carmedin does not endorse or verify encoded destinations.
The tool is provided as available, without a promise of universal scanner compatibility or legal clearance. These notices do not limit rights or obligations that applicable law does not allow to be limited.
Technical details and licenses
QR Code Model 2, high error correction, four-module minimum clear border, UTF-8 text, and client-side PNG/SVG export. The local fixed-grid integrity check reads the rendered symbol and checks its content and parity. It is not a camera-scanner certification.
