QR Code Generator
Point a code at a website, a WiFi login, a contact card, a WhatsApp chat or a map pin. Make one, or generate a whole sheet from a list. Rendered in your browser, never uploaded.
Make your QR code
Printing it small, or putting a logo in the middle? Raise error correction to Q or H so scanners can still read it.

Questions about making QR codes.
01Do QR codes made here ever expire?
No. These are static codes: the link or details are encoded directly in the pattern, so a code keeps working for as long as the address or information inside it stays valid.
02How do I make a QR code that joins guests to my WiFi?
Pick WiFi, enter the network name and password and choose the security type, usually WPA. Guests scan it with their phone camera and connect without typing the password.
03Can I create hundreds of QR codes at once?
Yes. Switch to bulk mode and paste one entry per line, adding a label before a | if you want it printed underneath. Export the whole set as a PDF sheet or save codes one by one.
04Should I download PNG or SVG?
Use SVG for print, signage and anything that gets scaled up, because it stays sharp at any size. PNG is fine for websites, slides and documents.
05Is the information I enter stored anywhere?
No. Codes are generated in your browser, so WiFi passwords, contact details and links are never sent to Kemafy or saved on a server.
