QR code generator
Type a link, some text, Wi-Fi details or a contact and the QR code shows up right away. It is free with no sign-up. What you make (inputs and results) is recorded to prevent illegal use.
When this is on, we store this link on the AppDogu server. It is deleted if nobody scans or changes it for one year. For 3 days after you make or change it, people who scan it first see where it goes.
If you lose the management link, there is no way to get it back. Please save it somewhere. It is also saved under My QR codes in this browser.
The password in the code is also recorded to prevent illegal use.

Printing tips
Dark dots on a light background scan best. Keep the white margin around the code, and try it with your own phone before you print a big batch. If the code may get scratched or dirty, raise error correction to Q or H.
Normal or dynamic
A normal QR code holds the content itself, so it works for as long as the image exists. A dynamic QR code holds a short AppDogu link, so you can change where it goes later and see how often it was scanned.
Questions people ask
Is this QR code maker free?
Yes. Both normal and dynamic QR codes are free, and there is no sign-up.
How long will my QR code work?
A normal QR code holds its content inside the image, so it has no end date. A dynamic QR code goes through our short link, and it is deleted if nobody scans or changes it for one year.
Can I see how many times it was scanned?
Yes, for dynamic QR codes. Your management link shows daily scan counts, split into Korea and elsewhere, with bots left out. Normal QR codes do not pass through our server when scanned, so they cannot be counted. What you make (inputs and results) and each scan are recorded to prevent illegal use.
