Frequently asked questions
Is the LonaDev QR code generator free?+
Yes. You can create QR codes and download them as PNG or SVG without creating an account.

Should I download PNG or SVG?+
PNG is convenient for documents and web use. SVG is vector-based and can be scaled for print without losing sharpness.
Are my QR code details uploaded?+
The QR image is generated in your browser. Your entered content is not sent to a LonaDev QR-generation server. Browser history is stored locally.
Will a QR code expire?+
A static QR code does not expire by itself. A website or other destination encoded in it can change or stop working.
How do I make a Wi-Fi QR code?+
Choose Wi-Fi, enter the network name and security type, then enter the password if the network requires one. Download and test the code before sharing.
Why won't my QR code scan?+
Use strong contrast, preserve a clear margin around the code, avoid printing too small, and test the final exported file with multiple camera apps.
A QR code stores information in a machine-readable pattern. Always test a downloaded code with a phone camera before distributing it, especially on packaging, signage or printed materials.
