What is a QR Code?

QR (Quick Response) code is a 2D barcode that can store various data such as URLs, text, and contact information.

Error Correction Levels

  • L: 7% recoverable - Most data
  • M: 15% recoverable - Balanced
  • Q: 25% recoverable - High reliability
  • H: 30% recoverable - Highest reliability

Use Cases

  • Website URL sharing
  • Business card contact info
  • Wi-Fi access info
  • Payment/transfer info

What is a QR Code Generator?

A QR (Quick Response) Code Generator is a tool that converts text, URLs, contact information, WiFi credentials, and other data into scannable two-dimensional barcodes. Originally invented in 1994 by Denso Wave for tracking automotive parts, QR codes have become ubiquitous in daily life — from restaurant menus and payment systems to digital business cards and marketing materials. This generator lets you create fully customizable QR codes with custom colors, shapes, logos, frames, and error correction levels, all processed entirely in your browser for maximum privacy.

  • Supports QR codes for URL, text, WiFi, business card, email, SMS, phone, and location
  • Customizing various shapes such as dot style and corner shape
  • Apply solid color, gradient color, and color theme presets
  • Generate brand QR code by inserting logo/image
  • Add speech bubbles, banners, round border frames, and CTA text
  • High resolution download in PNG/SVG format

  5. 5

    Download

    Download the QR code in PNG (raster) or SVG (vector) format. We recommend SVG for print and PNG for web.

Frequently Asked Questions

The error correction level refers to the rate at which data can be restored even if the QR code is partially damaged. There are four levels: L (7%), M (15%), Q (25%), and H (30%). The higher the level, the stronger the restoration ability, but the QR code becomes more complex. When inserting a logo, H level is recommended.

Error correction allows a QR code to scan normally even with an appropriately sized logo in the center. At level H (30%), a logo occupying about 20–25% of the QR code area is generally safe. You can adjust the logo size in this tool.

PNG is a raster format suited to digital uses such as websites, social media, and messaging. SVG is a vector format that remains sharp when enlarged, making it suitable for printed materials such as business cards, posters, and banners. Choose SVG for high-quality printing.

The QR codes generated by this tool are static, so they do not expire because their data is encoded directly in the code. Once created, they can be used permanently. However, a QR code that points to a URL will stop working if that URL changes or is removed.

A QR code can store up to 7,089 numeric characters, 4,296 alphanumeric characters, or 2,953 binary bytes. More data makes the code denser and harder to scan at small sizes. A URL-shortening service can make long URLs easier to encode.

Tips & Best Practices

  • Sufficient contrast in brightness between background and foreground colors must be maintained to increase scan recognition rate.
  • Quickly browse through different designs and choose your favorite with the random style feature.
  • It is convenient to automatically save your contacts by printing the vCard QR code on your business card.
  • Place your WiFi QR code in your cafe or office so visitors don't have to ask for the password.
  • QR codes for printed materials must be printed at a size of at least 2cm x 2cm to enable smooth scanning.
  • Adding CTA text such as ‘Scan Me’ to the frame can encourage more users to scan the code.
