A QR code (Quick Response code) is a two-dimensional barcode that stores data such as URLs, text, or contact information, readable by smartphone cameras.

How do I create a free QR code?

Visit isrange.com/qr-code, choose your content type (URL, WiFi, etc.), enter your content, and click Generate. Download as PNG or SVG instantly — no sign-up needed.

What file formats can I download?

You can download your QR code as PNG (best for digital use and screens) or SVG (best for printing, scales to any size without quality loss).

Can I create a WiFi QR code?

Yes. Select the WiFi type, enter your network name (SSID), password, and security type. Scanning the QR code connects devices to your WiFi instantly.

What error correction level should I use?

Use H (High/Max) for QR codes that will be printed or may be partially obscured. Use M (Medium) for standard digital use. Higher correction means slightly larger QR codes.

Are the QR codes permanent?

Yes. The QR codes generated here are static — the encoded data is permanent and does not expire. They work offline and do not require any server after download.

What is a QR code?

A QR code (Quick Response code) is a two-dimensional matrix barcode invented in 1994 by Denso Wave in Japan. Unlike traditional barcodes that store data in a single horizontal line, QR codes store data in both horizontal and vertical directions — allowing them to hold significantly more information in a smaller space.

Modern smartphones can scan QR codes natively with their camera app — no separate scanner app required. When scanned, the phone decodes the data and performs an action: opening a URL, connecting to WiFi, saving a contact, or dialling a number.

QR codes are built from three components: finder patterns (the three squares in the corners that orient the scanner), data modules (the black and white squares encoding your content), and error correction data that allows the code to be read even if up to 30% is damaged or obscured.
