QR Code

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.

• Support for multiple QR types: URL, text, WiFi, vCard, email, SMS, phone, and geolocation
• Full visual customization with dot styles, corner shapes, colors, and gradients
• Logo embedding with adjustable size, margin, and background dot hiding
• Decorative frames with customizable CTA text for marketing use
• Four error correction levels (L/M/Q/H) to balance data capacity and damage tolerance
• Auto-style and color theme presets for instant professional designs

How to Use

1. 1

   Select QR Type and Enter Content

   Choose the type of QR code you need (URL, text, WiFi, vCard, etc.) and enter the corresponding information. For WiFi, fill in network name, password, and encryption type; for vCard, enter contact details.

2. 2

   Customize Appearance

   Use the Shape, Color, Logo, and Frame tabs to customize your QR code. Choose dot styles, apply color themes or gradients, upload a logo, and add a decorative frame with call-to-action text.

3. 3

   Adjust Settings

   Set the output size in pixels, adjust the margin, and select an appropriate error correction level. Use higher error correction (Q or H) when adding a logo, as the logo covers part of the QR data.

4. 4

   Preview and Download

   Preview your QR code in real time as you make changes. When satisfied, download as PNG for general use or SVG for print materials that require scalable vector graphics.

5. 5

   Test Before Distributing

   Always scan your QR code with multiple devices and QR reader apps to verify it works correctly before printing or distributing, especially when using heavy customization or logo overlays.

Frequently Asked Questions

Tips & Best Practices

• Maintain high contrast between foreground and background colors for reliable scanning — dark dots on a light background works best.
• When adding a logo, always increase the error correction level to Q or H to compensate for the covered QR data area.
• Use SVG format for print materials to ensure your QR code remains sharp and scannable at any size.
• Test your QR code on multiple devices and apps before mass printing — some heavy customizations may reduce scan reliability.
• For WiFi QR codes, double-check the encryption type matches your router settings to avoid connection failures.
• Use the Auto Style feature for quick professional designs, then fine-tune individual settings to match your brand identity.
