QR Code Generator
How to Use This Tool
Creating a QR code takes just a few seconds. Start by selecting the type of QR code you want to generate — choose from URL, plain text, WiFi network, vCard contact, or email. Each type has its own input fields tailored to the data format.
For a URL code, simply paste your web address into the input field. For WiFi, enter your network name (SSID), password, and encryption type. For vCard, fill in the contact details you want to share.
Once your data is entered, the QR code generates automatically in real time. You can customize the appearance by changing the foreground and background colors using the color pickers. To add a logo or brand image, click the logo upload area and select an image from your device — it will appear centered on the QR code.
When you're satisfied with the result, click the download button and choose your preferred format: PNG for general use or SVG for scalable, print-quality output. The QR code is generated entirely in your browser — no data is sent to any server, and nothing is stored.
What is a QR Code?
A QR code (Quick Response code) is a two-dimensional barcode that stores information in a pattern of black and white squares. Originally invented in 1994 by Denso Wave for tracking automotive parts, QR codes have become one of the most widely used data-sharing tools in the world.
QR codes can store various types of data including website URLs, plain text, contact information, WiFi credentials, email addresses, and more. When scanned with a smartphone camera or QR reader app, the encoded data is instantly decoded and acted upon — opening a webpage, connecting to WiFi, or saving a contact.
The technology works by encoding data into a grid pattern using error correction algorithms. This means QR codes can still be read even if partially damaged or obscured. Most QR codes use Reed-Solomon error correction, which can recover up to 30% of lost data depending on the error correction level chosen.
Modern smartphones with iOS and Android can scan QR codes directly through their built-in camera apps — no separate app is needed. This universal compatibility has made QR codes essential for businesses, marketing, event management, contactless payments, and personal use.
QR codes come in different versions ranging from Version 1 (21×21 modules) to Version 40 (177×177 modules), with larger versions capable of storing more data. For most use cases like URLs and contact cards, smaller versions are sufficient.
