What is QR Code Generator Guide?

A QR (Quick Response) code is a 2D barcode that stores data a phone camera can read instantly. A QR code generator encodes your text, link, WiFi credentials, or contact details into a scannable image you can download and print.

How to use it

1. Choose what to encode: a URL, WiFi network, contact card, email, phone, or plain text.
2. Fill in the details for that type.
3. Customize the colors, size, and error-correction level.
4. Download your QR code as a PNG or SVG and use it anywhere.

Key features

• Many data types — Encode websites, WiFi passwords, vCards, email, SMS, phone numbers, and locations.
• Customizable design — Adjust foreground/background colors and size to match your brand.
• PNG & SVG export — Get a crisp raster image or an infinitely scalable vector for print.
• Error correction — Higher levels keep codes scannable even if part is damaged or covered by a logo.

Tips to get the most out of it

• Use SVG for large prints like posters so the code stays sharp.
• Keep strong contrast between the code and its background for reliable scanning.
• Test your QR code with a few phones before printing in bulk.
