Wi-Fi QR Code Generator
Create a QR code for a link, message, Wi-Fi network, or contact. Customize the design and download a scannable image.
Content type
URL QR Code Generator
Encode an absolute website address. Scanning a URL code does not send visitors through greneshadees.com and does not track scans.
https://example.com is an editable example. The preview is generated from this value until you change it.
This entry looks like a host name without http:// or https://.
Encode plain text, including English characters, numbers, punctuation, spaces, line breaks, and Unicode. Line breaks are preserved. Content is not truncated silently.
Build a mailto URI. Compatible devices may open an email application. Scanning does not send an email from this website, and empty subject or body fields are allowed.
Compatible devices may offer to open the phone dialer after scanning. Scanning does not automatically place a call. Country codes are not assumed.
SMS URI support varies by operating system and scanning application. This website does not send messages, and scanning does not automatically send an SMS.
Wi-Fi QR codes store network credentials in readable form. Anyone who scans or decodes the code may be able to read those details. QR encoding is not encryption and does not protect the password.
Creates a vCard 3.0 payload. Contact import behavior depends on the scanning device and application. Optional empty fields are omitted.
Customize Your QR Code
Sufficient contrast improves scan reliability. A particular contrast ratio does not guarantee scanning. Avoid light-on-light combinations, transparent backgrounds, busy photographs behind the code, and untested inverted colors.
QR Image Size
The selected export size includes the quiet zone. Modules are drawn with integer pixel sizes. If the chosen pixel count is not a multiple of the matrix plus quiet zone, leftover pixels become extra background padding so module edges stay sharp.
The quiet zone is a light margin of at least four modules. It cannot be removed. Preview, PNG, SVG, and print output all keep it.
Error Correction
Higher levels recover from more damage or obstruction, but they reduce payload capacity or enlarge the matrix. A higher level does not guarantee a successful scan, and a damaged code is not always readable.
Selected level: M · — · —
Print Your QR Code
Printer scaling can change the final size. Use actual-size or 100% scaling when the dialog offers it. Results vary by printer, paper, and device camera. A QR code will not scan from every distance.
Your QR Code Preview
Enter valid content to generate a QR code.
Zoom changes only the on-screen preview. It does not change encoded content, QR version, export size, error correction, or the quiet zone.

Wi-Fi payloads and privacy
The encoder writes WIFI:T:...;S:...;P:...;; with backslash escaping for \ ; , : and quotation marks. Hidden networks add H:true;. Open networks omit an unnecessary password field.
The password never leaves this browser, is not written to localStorage, and is not placed in the page URL. Show/Hide only changes the field on screen.
Anyone who scans or decodes the image can read the credentials. Treat the code like a printed password. Read How to make a QR code for Wi-Fi.
