QR Code Generator

A QR code holds text. Phones recognise some kinds of text and offer to act on them:

Whatever is in the box is exactly what the code contains: nothing is added, shortened or changed.

Choose Wi-Fi network above the box, then fill in the form:

• Network name: exactly as your devices show it, including capitals and spaces.
• Security: WPA, WPA2 or WPA3 for almost every home and office router; WEP only for very old ones; None for an open network, which needs no password.
• Password: shown as you type so you can check it. It isn’t saved anywhere.
• Hidden network: tick it if the network doesn’t appear in phones’ Wi-Fi lists.

The generator writes the text phones expect, such as WIFI:T:WPA;S:Cafe Guest;P:coffee-2026;;, and adds the backslashes that semicolons, commas, colons and quotes in a name or password need. Download card saves a printable PNG with the code and the network name and password written underneath. There’s more in the Wi-Fi QR code guide.

Anyone who scans the code, or photographs it, can read the password, so use a guest network for codes on public display.

The vCard preset makes a contact card. Every line makes the code denser, so add only what you need:

BEGIN:VCARD

N (surname;first name) and FN (the name shown) are both required.

This generator makes static QR codes: your link or text is stored in the pattern itself, with no short link or redirect in between. So:

• It never expires. It works for as long as the link inside it works, with no account or subscription.
• Nobody tracks scans. Scanning doesn’t go through any service, so no one, including us, sees who scans it.
• It can’t be edited once printed. To change what it says, make a new code.

Dynamic QR codes contain a short link to a service that redirects to your real address. The service can count scans and change the destination, but the code stops working if the service or your account ends. With a static code, you can get similar results yourself, as the questions below explain.

• Size: at least 2 cm (¾ inch) across. A common rule of thumb is a tenth of the scanning distance: a poster read from 2 metres needs a code about 20 cm wide.
• Clear space: scanners need an empty margin, the quiet zone. The download includes the four-module margin the QR standard asks for (a module is one small square), so don’t crop it off. On a busy background, keep that space clear or add a white border with the Border tool.
• Contrast: use a dark code on a light background. Pale colours, and light codes on dark backgrounds, fail on some scanners. The Color Palette Extractor can find your brand colour’s hex code.
• Error correction: higher levels survive scratches and dirt but make the pattern denser: one short link needed 25 × 25 modules at Medium and 33 × 33 at High. Use Medium for screens and clean print, Quartile or High for stickers and outdoor signs.
• Less text: a short link makes fewer, bigger modules, which scan more easily.
• Test before printing: scan a proof at its final size, with more than one phone, from the distance people will use.

For screens, a PNG of 256 or 512 pixels is plenty. For print, choose SVG: it’s drawn with shapes rather than pixels, so it stays sharp at any size, and most design and print software accepts it. A 1024-pixel PNG is about 8.7 cm (3.4 inches) wide at 300 dpi. To put codes on printable pages, turn them into a PDF.

The code is made by your browser, on your own device, so what you type, including Wi-Fi passwords, is never sent to a server.

You can check this yourself: open your browser’s developer tools, watch the Network tab and generate a code. You’ll see the page’s own files and anonymous page-view counts, described in our privacy policy, but nothing containing your text. After your first visit, the generator works offline too.
