FAQ
Q. Are the QR codes permanent?
Yes, once created, QR codes are permanent. However, for URL QR codes, if the website goes offline, the link won't work.
Q. Can I use custom colors?
Yes! As long as there's sufficient contrast between foreground and background, the QR code will scan properly. The foreground should be darker than the background.
