◼️ QR Code Generator
Create customizable QR codes instantly in your browser. Supports URLs, plain text, email addresses, phone numbers, and Wi-Fi credentials. Adjust size, error correction, and colors, then download as PNG.
How to Use the QR Code Generator
The QR Code Generator creates instant, customizable QR codes directly in your browser — no account, no watermarks, completely free. Start by selecting a content type from the preset tabs: URL, Text, Email, Phone, or Wi-Fi. Paste or type your content in the input area. For URLs, include the full address with https://. For Wi-Fi credentials, use the format WIFI:T:WPA;S:NetworkName;P:Password;;. Customize your QR code using the options below: choose the image size from 128×128 to 512×512 pixels, select the error correction level (L recovers 7% damage, M 15%, Q 25%, H 30% — higher levels make the QR code denser but more resilient), and pick custom foreground and background colors. The QR code updates instantly as you type. Click Download PNG to save the image to your device. Use higher error correction when printing the QR code or placing it on a physical surface where it might be partially obscured. Your data never leaves your browser.
Frequently Asked Questions
What is a QR code?
›
A QR code (Quick Response code) is a two-dimensional barcode that can be scanned by any smartphone camera or QR reader app. It encodes data — most commonly a URL — as a matrix of black and white squares. QR codes can hold up to about 4,296 alphanumeric characters and are used for linking to websites, sharing contact info, encoding Wi-Fi credentials, payments, and product tracking.
What is error correction in QR codes?
›
Error correction allows a QR code to be read even if part of it is damaged, dirty, or obscured. There are four levels: L (7% can be restored), M (15%), Q (25%), and H (30%). Higher error correction adds redundant data, making the QR code larger and denser but more reliable. Use H level for QR codes on physical surfaces like stickers, packaging, or posters.
How do I encode Wi-Fi credentials in a QR code?
›
To share Wi-Fi credentials via QR code, use this format as your content: WIFI:T:WPA;S:YourNetworkName;P:YourPassword;; Replace WPA with WEP if your network uses that security type, or use nopass for open networks. When scanned, Android and iOS will offer to automatically join the network without manually typing the password.
What is the maximum amount of data a QR code can hold?
›
QR codes can hold up to 7,089 numeric characters, 4,296 alphanumeric characters, 2,953 bytes of binary data, or 1,817 Kanji characters. In practice, shorter content produces a simpler, easier-to-scan QR code. For URLs, use a URL shortener to reduce the amount of data and make the QR code less dense and easier to scan from a distance.
