Generate QR codes for text, URLs, WiFi credentials, and more
QR Code stands for "Quick Response" code. It's a two-dimensional barcode that can store various types of information.
This QR code generator runs entirely in your browser using the open-source qrcode JavaScript library, so nothing you type is ever uploaded to a server. It supports eight content types: plain text, website URLs, email addresses, phone numbers, SMS messages, WiFi credentials, contact cards (vCard 3.0), and calendar events. Instead of hand-formatting strings like WIFI:T:WPA;S:MyNetwork;P:password;; or a vCard block, you simply fill in the labeled fields and the tool assembles the correctly structured payload for you, regenerating the preview live as you type.
QR codes (short for Quick Response codes) were invented in 1994 for tracking auto parts, but their ability to bridge physical and digital content made them ubiquitous on menus, tickets, packaging, and business cards. Every code includes built-in error correction, which means a damaged or partially obscured code can often still scan correctly. That resilience has a trade-off worth knowing: the more data you squeeze in, the denser the pattern, so short URLs scan faster and more reliably than long ones. A quiet zone of blank margin around the code, which this tool sets automatically, is also required for reliable scanning.
For best results, choose SVG when printing at large sizes since vector output stays sharp at any scale, and always test-scan with a real phone before sending something to print. If you also need secure credentials for the WiFi or account details you are encoding, the Password Generator can create strong values first, and the Random Number Generator is handy for raffles or prize draws linked from your code.
Yes. QR codes themselves are an open standard with no licensing fees, and anything you generate with this tool is yours to print, publish, or distribute. You can use them on business cards, flyers, product packaging, menus, or signage without any restrictions or recurring costs.
No. The codes generated here are static QR codes, meaning the data is encoded directly into the pattern itself. They never expire and do not depend on any redirect service, so a printed code will keep working as long as the content it points to remains valid. Just note that a URL code only works if the webpage behind it stays online.
PNG is a raster image fixed at the pixel size you select (200 to 500 pixels), which is ideal for websites, presentations, and quick sharing. SVG is a vector format that scales to any size without blurring, making it the better choice for large prints like posters or banners where you need crisp edges at high resolution.
The more data you encode, the denser the module pattern becomes, and dense codes are harder for phone cameras to read quickly, especially at a distance or in low light. A short URL scans far more reliably than a long one with tracking parameters, so use a concise link whenever possible and test-scan before printing.
The tool encodes your network name, password, and security type (WPA/WPA2, WEP, or open) into a standard WiFi connection string. When someone scans the code with a supported phone, they are prompted to join your network instantly without typing a password. This is popular for guest WiFi in cafes, offices, and rentals.
