Worked examples
Concrete numbers and cases you can check against the tool above.
Event flyer URL at print size
Encode the final HTTPS URL (not a redirect you might change later), export at 512 px or larger, and print at least 1 inch square with a quiet zone around the modules. Test with a phone camera in the same lighting as the venue. Dense Wi‑Fi payloads or very long URLs need a larger print.
Wi‑Fi guest card
A WIFI: payload includes SSID, type (WPA/WPA2), and password. Short SSIDs scan more reliably. Do not put the admin password on a public poster — use a guest network.
When to use QR Code Generator
QR codes bridge print and digital — menus, posters, packaging, and Wi‑Fi cards. Generating a PNG in the browser means you can test scans immediately and avoid third-party branding on the code.
Common use cases
- Put a URL on event flyers that open the registration page.
- Share Wi‑Fi credentials with guests without spelling the password.
- Link product packaging to a support or warranty page.
- Add a scannable resume or portfolio URL to a business card.
Inputs and outputs
- Input: Text, URLs, and structured payloads supported by the form
- Output: PNG QR code image

Frequently asked questions
- Can I make a Wi‑Fi QR code?
- Yes, when Wi‑Fi mode is available — guests can scan to join without typing the password.
- How much text can a QR code hold?
- Short URLs work best. Very long text makes denser codes that can be harder to scan when printed small.
- Do you store what I encode?
- No. Generation happens in your browser.
