QR Code Generator

A QR code generator encodes a link, a WiFi network, or a block of text into a scannable pattern. Pick a tab, type your content, and the code renders as you type — entirely in your browser. Download it as a PNG at three sizes or as a scalable SVG. Nothing you enter is sent anywhere.

Why local encoding matters here more than usual

For a plain URL it hardly matters who does the encoding. For WiFi it matters a great deal, because aWiFi QR code contains your actual password in plain text. Typing your home or office network credentials into a random website's form, so that its server can draw a picture for you, is precisely the habit worth breaking. Everything on this page is encoded by JavaScript on your device: load the page, turn off your connection, and the generator still works. That is the simplest possible proof that nothing is being transmitted.

Static codes: no expiry, no tracking, no hostage situation

Many free QR services quietly produce dynamic codes that point at their own domain and then redirect. That lets them count every scan, and it means your printed codes stop working the day the free tier lapses or the company disappears. Everything generated here is static: the URL, text, or credentials live inside the pattern. It will scan identically in twenty years, nobody can meter or intercept it, and for WiFi and text codes the scanning phone needs no internet connection at all.

Making a WiFi code for guests

Enter the network name, the password, and the security type — almost every modern router is WPA, covering WPA2 and WPA3 — then download the PNG. Both iPhone and Android cameras handle these natively. Print it for a guest room, a café counter, an office reception, or an Airbnb welcome book. If you rotate the password, regenerate the code; it takes seconds. For a network that does not broadcast its name, tick Hidden network so the payload carries the flag phones need.

Choosing size, format, and error correction

Printing codes that actually scan

1. Keep the quiet zone. The code includes a small margin, but leave extra clear white space around it in your layout — crowding the edge is the most common print failure.
2. Do not invert or tint it. Dark pattern on a light background is what scanners expect.
3. Mind the minimum size. About 2 cm square works at arm's length; a code read from across a room needs to be far bigger.
4. Shorten the URL first. Less content means a less dense pattern, which scans faster and prints smaller.
5. Test on an iPhone and an Android from the real distance, on the real printed material, before ordering a hundred of them.

What QR codes are genuinely good for

The honest list is shorter than most marketing suggests. They work well where typing is the friction: joining a WiFi network, opening a menu or booking page, sharing contact details on a card, linking a printed poster to a video, or passing a long URL from paper to phone. They work poorly as decoration, as a substitute for a memorable short link, or anywhere the reader cannot comfortably get a camera close. And because a code hides its destination, people are increasingly wary of scanning them in public — so put the destination in readable text next to the code, which is both more trustworthy and more accessible.
