This tool uses the open-source qrcode library to generate standard-compliant QR codes entirely in your browser. Here's the process:
| Type | Format | Example |
|---|---|---|
| URL | https://... | Scanning opens the link directly |
mailto:... | Opens email client with address pre-filled | |
| Phone | tel:... | Dials the number on mobile |
| vCard | BEGIN:VCARD... | Imports contact into phone's address book |
| WiFi | WIFI:T:WPA;S:...;P:...;; | Auto-connects to the network |
| Text | Raw text | Displays message when scanned |
| Level | Recovery | Best For |
|---|---|---|
| L | 7% | Clean digital use, smallest codes |
| M | 15% | Default — general purpose |
| Q | 25% | Printed materials, moderate wear |
| H | 30% | Damaged surfaces, curved objects, small print |
These are real content samples you can paste in to verify that your scanner reads the output correctly:
| Type | Sample Input | Expected Scan Result |

| Text | Hello from ToolHubNest! | Displays: Hello from ToolHubNest! |
| vCard | Name: Alex Chen · Email: [email protected] | Adds contact "Alex Chen" |
| WiFi | SSID: HomeNet · Password: wifi123 | Connects to HomeNet |
All outputs are validated against the ISO/IEC 18004 QR code standard.
A QR (Quick Response) code is a two-dimensional barcode that stores data as a matrix of black and white squares. Smartphones and dedicated scanners read the pattern and decode it into text, URLs, contact information, or other data.
This generator supports URLs, plain text, vCard contacts, WiFi configuration (SSID + password), email addresses, and phone numbers. Use the type selector or let auto-detection choose the best format.
L (Low) works best when the QR code is clean and unobstructed — it produces the densest codes. M (Medium) is a good default for most uses. Q (Quartile) and H (High) can recover more data if the code is damaged, printed on textured surfaces, or partially obscured.
No. This QR code generator runs entirely in your browser using the open-source qrcode library. The text you enter never leaves your device. Disconnect from the internet and it still works.
PNG is a pixel-based image at your chosen size — perfect for screens and social media. SVG is a vector file that scales to any size without pixelation, making it ideal for print, logos, and large-format displays.
