🪄 Use cases

URLs on signage & flyers

Turn a site or menu URL into a QR for posters and business cards. Match your brand with colors and a logo.

Sharing Wi-Fi

Just enter the SSID and password. Guests connect to Wi-Fi by simply scanning with their camera.

Contacts & events

Add a contact to the address book in one tap with vCard, or let people add an event with the calendar format.

Mass coupons & tickets

Paste multiple lines from a CSV to batch-generate unique QR codes and hand them out bundled in a ZIP.

🔒 Privacy

QR generation, rendering and ZIP packaging all happen entirely in your browser. The strings you enter and any logo image are never sent to a server.

❓ FAQ

Can I use the generated QR codes commercially?

Yes. There are no usage restrictions on the generated QR codes. Use them freely on flyers, business cards, product packaging and more — no registration or attribution required.

Which error-correction level should I pick?

M (15%) is usually enough. Choose H (30%) when overlaying a center logo or for print that may get smudged, to keep it easy to scan.

Can I encode Japanese or emoji?

Yes. It encodes in UTF-8 (Byte mode), so Japanese, Chinese and emoji work correctly. Note that more characters increase the number of modules.

How many can I make in batch mode?

Up to 500 items, one line per code. Paste multiple lines copied from a CSV or table and download them all bundled as a ZIP.
