QR Code for URLs, Wi-Fi, and marketing
Marketing materials, menus, and Wi-Fi sharing cards are the most common everyday use of QR Code, typically encoding a URL or a short structured text payload.
Preconfigured for marketing use
This experience raises error correction to High ("eclevel": "H") instead of the primary's Medium, for scans at typical smartphone-camera distance off printed collateral.
Example data
The generator is seeded with "http://goo.gl/1bis", distinct from the primary's "http://goo.gl/0bis" and rendered at eclevel H instead of M; replace it with your own URL or text.
Workflow
Enter your URL or text, confirm the live preview scans correctly at your intended print size, then export PNG for digital use.
Job-specific settings
Raise eclevel to H if the code will be printed small or partially obscured by a logo overlay.
Common mistakes
Printing the code too small for its data length/error-correction combination is the most common scan-failure cause.
Standard
QR Code is defined by ISO/IEC 18004.

FAQ
Does level H always produce a bigger code than M?
No. For the same payload, level H uses more capacity for redundancy and can force a larger auto-selected version than M, but short payloads can remain in the same version. With the pinned encoder, the one-character payload A is the same 84x84 rendered size at M and H.
