QR Code Generator

What is QR Code?

A QR code is a 2D barcode that phones scan instantly to open a URL, read text, or join a Wi-Fi network. Generating one lets you bridge print and screens to the digital world — posters, business cards, packaging, menus, and event check-ins. This generator builds the code entirely in your browser and exports crisp PNG (raster) or SVG (vector) files.

How to generate a QR code

1. 1Enter the content — a URL, plain text, or Wi-Fi details.
2. 2Pick an error-correction level (higher survives more damage but is denser).
3. 3Preview the QR code, then download it as PNG or SVG.
4. 4Test the scan with a phone before printing or publishing.

Use Cases

Code Examples

WIFI:T:WPA;S:MyNetwork;P:MyPassword;;

Key Concepts

Error correction levels

L≈7%, M≈15%, Q≈25%, H≈30% of the code can be damaged and still scan. Higher levels add redundancy (denser code).

PNG vs SVG

PNG is a fixed-resolution raster image; SVG is vector and stays sharp at any size — best for print and large formats.

Quiet zone

The blank margin around a QR code. Scanners need it; cropping too tightly can make a code unreadable.

Tips & Best Practices

• ▸Use level H when the code will be printed small or may get dirty/scratched (packaging, outdoors).
• ▸Prefer SVG for print so the code stays crisp at any size.
• ▸Keep the quiet-zone margin — don't crop right to the code's edge.
• ▸Always test a scan on a real phone before mass printing; a broken URL on 1,000 flyers is expensive.
