How to create a QR code
- Choose the QR code type.
- Enter the required information.
- Customize the QR code if desired.
- Check the preview.
- Download PNG or SVG.
- Before printing or publishing, test the QR code with a real phone or camera.
- Available types are web link, text, Wi-Fi, contact card, phone, email, SMS and location. Complete the fields for the selected type; Wi-Fi security and hidden-network settings must match the network.
- Adjust size, clear border, colors and error correction. If generation fails, shorten the content. Keep strong contrast and a clear border, then test the downloaded code at its intended display or print size.
Reliable output
The quiet zone is the clear space around the QR code that helps scanners recognize it.
Strong foreground/background contrast improves scanning reliability.
SVG is best for scalable graphics; PNG suits most common digital uses.
Choose the right QR content for the intended action
Cezar QR Code Generator encodes a web address, text, Wi-Fi settings, contact details, phone number, email, SMS or coordinates. A scan can open the matching app on a compatible device. Check the destination and field values before sharing: the code contains the entered information, not a managed redirect or editable campaign.
Use PNG or SVG for digital and printed QR codes
PNG is convenient for everyday documents and digital sharing; SVG can scale for layouts and printing. A clear border and strong contrast help scanners distinguish the code. More content makes the pattern denser, so test the final output on a real phone. Error correction does not remove the need for a readable design.
Questions about QR codes
Can I change a downloaded code's destination later?
The encoded content is fixed. To change it, generate and distribute a new code. The tool does not provide managed dynamic redirects.
Is a Wi-Fi password hidden from people scanning the code?
No. A Wi-Fi code contains the network credentials. Share it only with people who should have that information.
Does generating an email or SMS code send a message?
No. Scanning can open a compatible messaging app with the encoded fields. Sending is a separate action on the scanning device.
