What this is
QR Generator makes QR codes for links, Wi-Fi networks, UPI payments, contacts, text messages, email, phone numbers, calendar events and map locations. It is free, it needs no account, and it adds no watermark.
There is also an Android app, which shares this site's encoder behaviour and reports into the same anonymous usage statistics. The two are built to behave the same way, so a code made on one is identical to a code made on the other.
Why it works the way it does
Most free QR generators send whatever you type to a server, which is how your Wi-Fi passphrase or a client's phone number ends up in somebody's log file. A good number go further and put a redirect of their own in the middle of your link, so they can count the scans — and, in some cases, start charging you once the code is printed and cannot be changed.
This one encodes in your browser. The page has no upload path for the content of a code, and the codes it produces point directly at whatever you entered, with no redirect in between. That means they keep working whether or not this site does, and it means they cannot expire.
The trade-off is honest: because there is no redirect, we cannot offer scan analytics or let you change a code's destination after printing. Those features require exactly the thing we chose not to build.
Who makes it
ABLN Technologies, an independent software developer. QR Generator Lite is one of our apps; the website and the Android app are maintained together.
If something is wrong, unclear, or missing, tell us — bug reports about codes that fail to scan are especially welcome, since that is the failure that matters most and the hardest for us to find on our own.
