What is a QR code and how does it work?
A QR (Quick Response) code is a two-dimensional barcode: a grid of black and white squares that stores data in a pattern a camera can read in a fraction of a second. Unlike a traditional barcode, which only holds a short string of numbers read in one direction, a QR code stores information in both directions at once, which is why it can pack in a full web address, a WiFi password, or an entire contact card in a small square.
When a phone camera or scanning app points at the code, it looks for three distinctive squares in the corners of the grid. Those squares tell the scanner how the code is oriented and how large it is, even if the photo is taken at an angle. Once the scanner has its bearings, it reads the black-and-white pattern, corrects for any smudges or glare using built-in error-correction data, and converts the pattern back into the original text, link, or contact details.
How to create a QR code
The general process is the same regardless of what the code will contain:
- Pick the type of content — a link, WiFi details, a message, and so on.
- Fill in the relevant fields. Each type above only asks for what it actually needs.
- Adjust size, colors, and error correction if you want something other than the defaults.
- Click Generate, then check the preview looks right.
- Download it as a PNG (or SVG, for print work) or print it directly from this page.
Creating a URL QR code
Select "Website / URL," paste the address, and generate. If you leave off "https://", the tool adds it automatically so the link still opens correctly when scanned.
Creating a WiFi QR code
Select "WiFi," enter your network name (SSID) exactly as it appears on your router, choose the encryption type, and add the password. Scanning the resulting code lets a guest's phone join the network without anyone reading the password out loud — handy for cafés, offices, and guest rooms. Just remember that anyone who scans it can also see or share the password, so treat the printed code with the same care as the password itself.
Creating a WhatsApp QR code
Select "WhatsApp," enter the phone number in international format, and optionally add a pre-filled message. Scanning the code opens a chat with that number and drops the message into the text box, ready to send — a common shortcut for customer support lines and small businesses.
Creating a vCard (contact) QR code
Select "Contact (vCard)" and fill in a name plus at least a phone number or email. The generated code, when scanned, offers to save the person directly as a new contact — useful on business cards, name badges, and email signatures instead of making someone type a number by hand.
Common QR code use cases
- Businesses: menus, product packaging, receipts, storefront WiFi, review links, and payment or contact details on signage.
- Students: linking a printed worksheet to a video explanation, sharing a study group's contact card, or pointing classmates to a shared document.
- Teachers: attaching a code to handouts that links to a reading, a form, or a class calendar event, saving time compared to reading out a long URL.
- Events: printing an event QR code on an invitation so guests can add the date, time, and location straight to their calendar with one scan.
Static vs. dynamic QR codes
This tool generates static QR codes: the destination or content is encoded directly into the pattern itself, permanently. That makes them ideal for anything that will not change — a WiFi password, a fixed phone number, an address.
Dynamic QR codes work differently: the code points to a short redirect link controlled by a separate service, and that service forwards the scanner to whatever destination is currently configured. Because the redirect can be edited after printing, dynamic codes are used when the destination might change or when someone wants scan analytics. They also depend on that redirect service staying online. This tool does not create dynamic, trackable codes — every code you generate here is static and works independently of any outside service.
Do QR codes expire?
A static QR code does not expire on its own — the data is baked into the pattern, so it will scan correctly for as long as the printed or displayed image is intact. What people usually mean by "my QR code stopped working" is either a dynamic/short-link code whose underlying service was shut down or whose subscription lapsed, or a static code pointing to a web page that was later deleted or moved. The code itself doesn't have a timer; the content it points to might.
How to scan a QR code
Most modern phones can scan a QR code directly from the built-in camera app — no separate app needed. Open the camera, point it at the code so all three corner squares are visible, and wait for the on-screen prompt to appear, then tap it. If your camera doesn't detect codes automatically, check its settings for a "scan QR code" toggle, or use a dedicated scanner app.
How to download and print a QR code
Use the Download PNG button for sharing digitally or printing at a normal size — it's a raster image, so keep the requested size reasonably close to how large it'll actually be printed. For posters, banners, or professional print runs, the Download SVG button gives you a vector file that stays crisp at any size. The Print button sends just the QR code to your printer, without printing the rest of the page around it.
Privacy considerations
Everything on this page — building the code, applying colors, adding a logo, and generating the final image — happens locally in your browser. Nothing you type here is sent to a server. That said, a QR code is only as private as what you put into it and where you display it: a WiFi QR code printed on a public wall reveals the password to anyone who photographs it, and a vCard code shared widely exposes whatever contact details you included. Treat sensitive QR codes the way you'd treat the information itself.
