What is a QR code?

A QR code is a two-dimensional barcode that stores information such as URLs, WiFi credentials or text. Read more on Wikipedia.

How do I generate a QR code on this site?

Can I make a WiFi QR code?

Absolutely. Choose the WiFi option, enter your SSID and password, then generate. Watch a quick tutorial.

Do the QR codes expire?

No. Static QR codes last indefinitely—as long as the underlying link or data remains valid.

Can I customize the color or size of my QR code?

Yes. Pick any foreground and background color and select from three preset sizes (150 × 150, 220 × 220 or 300 × 300 px). For posters or signage, choose the largest size so the code remains sharp after scaling.

Will my QR code still work if I change the link later?

Static QR codes always point to the exact data you encoded. If you may need to update the destination, create a short redirect URL (e.g. yourdomain.com/go) and encode that instead—you can change the redirect target any time without reprinting the code.

Are static QR codes safe for personal or business use?

They are as safe as the content you embed. Double-check every URL before generating, and avoid putting sensitive information (plain-text passwords or private documents) in a publicly posted code. For WiFi, use a guest network with limited permissions.
