How to Create a QR Code
Choose Content Type
Pick what your QR code should contain: a URL or text, WiFi login credentials, an email address, or a phone number. Each mode formats the data correctly.
Customize Appearance
Set the QR code size and pick custom foreground and background colors. Keep enough contrast between them for reliable scanning.
Generate & Download
Click Generate, preview the result, then download as a high-quality PNG. The QR code is ready to use in print, websites, or digital materials.
What Is a QR Code?
A QR (Quick Response) code is a two-dimensional barcode that stores data in a pattern of black and white squares. Originally invented in 1994 by a Japanese company for tracking automotive parts, QR codes have exploded into mainstream use over the past decade. They're now everywhere — restaurant menus, business cards, product packaging, event tickets, and payment terminals.
The fundamental appeal is speed and convenience. Scanning a QR code with a smartphone camera takes about one second and instantly opens a URL, connects to WiFi, or adds a contact — no typing required. For businesses, this bridges the gap between physical media and digital experiences effortlessly.
QR codes are remarkably resilient too. They use Reed-Solomon error correction, meaning a code can lose up to 30% of its surface area (from damage, dirt, or partial obstruction) and still scan correctly. This is why you can print QR codes on napkins, outdoor signs, and packaging that gets handled roughly — and they still work reliably.
One thing many people don't realize: QR codes can store different data types beyond simple URLs. Our generator supports WiFi network credentials (so guests can join your network by scanning instead of typing a complex password), pre-composed email messages, and phone numbers. Each type uses a standardized format that smartphone cameras automatically interpret — the user scans the code and their phone takes the appropriate action without any additional apps or setup.
Why Use Our QR Code Generator?
Custom Colors
Pick any foreground and background color to match your brand. Just make sure there's strong contrast between them — QR scanners need clear distinction.
Multiple Content Types
Beyond URLs, create QR codes for WiFi credentials, email addresses, and phone numbers. Each type triggers the appropriate action on the scanner's device.
Scalable Sizes
Generate codes from 200×200 to 500×500 pixels. Smaller codes work for digital screens; larger ones are better for print materials where scanning distance matters.
Offline Generation
After the page loads, QR codes are generated entirely in your browser — no server calls, no data collection. Works even without an internet connection.
Frequently Asked Questions
For print materials, use at least 300×300 or larger. The minimum practical printed size is about 2×2 cm (roughly 0.8×0.8 inches) — any smaller and phone cameras may struggle to focus. For outdoor signage or materials scanned from a distance, go larger. A general guideline: the scanning distance should be about 10 times the QR code's width.
Yes — pick any foreground and background colors. The critical requirement is contrast: the foreground (the square modules) must be significantly darker than the background. Avoid low-contrast combinations like light gray on white or dark blue on black, as these may not scan reliably on all devices.
Static QR codes (like the ones this tool generates) never expire. The data is encoded directly into the pattern. As long as the physical code exists and is scannable, it will work. Dynamic QR codes (which point to a redirect URL) can expire if the redirect service shuts down, but that's a different technology.
A single QR code can store up to about 4,296 alphanumeric characters or 7,089 numeric digits. For URLs, that's more than enough — even very long URLs with tracking parameters fit comfortably. For plain text, you can encode several paragraphs. Longer content creates more complex (denser) codes that may be harder to scan from a distance.
The WiFi QR code is generated entirely in your browser — your network name and password are never sent anywhere. Anyone who scans the resulting code will be able to connect to your WiFi, so treat the printed code like you would the password itself. Perfect for guest networks, Airbnbs, and offices.
