AI Generation Prompt
Technical Specification: Free Wi-Fi QR Code Generator
Overview
A high-performance, browser-based tool that enables users to generate machine-readable QR codes for connecting to Wi-Fi networks. The tool focuses on privacy, ease of use, and high reliability, ensuring that the generated codes are instantly compatible with all major mobile operating systems.
Core Features
- Live QR Generation: Instant visual update as the user types their SSID, password, and selects encryption protocols.
- Protocol Support: Dropdown selection for WPA/WPA2/WPA3, WEP, or No-Authentication networks.
- Hidden Network Toggle: Specific flag for networks that broadcast hidden SSIDs.
- Export Capabilities: Buttons to download the QR code as a high-resolution PNG image or a scalable SVG for printing.
- In-Memory Logic: Zero network requests or storage usage. All processing happens in the client's CPU.
User Interface (UI) Layout
- Header: Clean, professional title area with a brief helper text describing the utility.
- Main Tool Area (Split View):
- Left Column (Inputs): Clean form fields with floating labels for SSID and Password. Dropdowns for encryption selection. An "Advanced" accordion for adjusting the QR code error correction level (defaulting to "Medium").
- Right Column (Preview): A prominent white card with a subtle drop shadow containing the rendered QR code. A clear "Download" button sits below the code.
- Footer/Support: (None required by constraints. Minimalistic interaction only).
Design & Aesthetic
- Palette: Use a crisp professional palette:
bg-slate-50for background,#2563eb(Royal Blue) for primary buttons, and#1f2937for typography. Use high-contrast elements for accessibility. - Transitions: Smooth easing functions for form interactions (e.g., input field borders glow softly on focus).
- Responsive Design: Stack the columns vertically on mobile devices. The QR code container should adjust its max-width dynamically based on the viewport.
Technical Constraints & Implementation
- Architecture: Single HTML file. Use CDN links for
tailwindcssand a reliableqrcode.jslibrary. - Security/Compatibility:
- NO LocalStorage/SessionStorage/Cookies: This app must run in a sandboxed iframe. If state needs to be managed, use standard JS variables.
- No Popups: Use CSS-based modal overlays for success messages or printer dialog triggers.
- External Links: Any outbound links must use
target="_blank"andrel="noopener noreferrer".
- Development Directives:
- Use
window.print()functionality for the print feature. - Ensure the SVG export preserves high-contrast vectors.
- Use modern ES6+ JavaScript syntax without transpilation.

Frequently Asked Questions
Everything you need to know about using this application.
How does this Wi-Fi QR code generator work?
It uses the standard Wi-Fi network configuration protocol (WPA/WPA2/WEP) to encode your network credentials into a machine-readable QR matrix. When you scan the generated code with a modern smartphone camera, the device automatically identifies the network configuration and prompts the user to join without manually typing the password. The entire process happens locally within your browser, ensuring no network data is sent to external servers. By relying on client-side JavaScript, we maintain maximum privacy for your sensitive wireless credentials while providing an instant, reliable QR generation service for homes or offices.
Is my Wi-Fi password safe using this tool?
Yes, your network credentials remain entirely private. This application operates locally on your device without any server-side processing, database storage, or logging mechanisms. We do not transmit your SSID or password over the internet at any point during the QR code generation process. Because this tool is architected as a single-file application without persistent storage or external communication, your Wi-Fi details never leave your computer's memory. Once you refresh or close the page, the data is completely erased, offering a high-security workflow for generating connection codes.
Will this QR code work on all smartphones?
Yes, the generated QR codes adhere to the global standard for Wi-Fi network provisioning recognized by modern Android and iOS devices. Simply point the default camera application at the QR code, and it will interpret the payload, identifying the SSID and password needed to initiate the connection handshake. While older devices without native QR scanning support might require a third-party scanning app, nearly all current smartphones provide this functionality out-of-the-box. This ensures a seamless guest onboarding experience for visitors connecting to your wireless network.
Can I customize the QR code for branding purposes?
This tool focuses on high-contrast, high-scanability generation to ensure compatibility across various lighting conditions and camera lenses. By prioritizing error correction levels and standardized formatting, we guarantee that the codes are consistently scannable by even entry-level smartphone cameras. Rather than focusing on aesthetic customization that could reduce scan reliability, we emphasize functionality. The tool allows you to specify the encryption type, which is critical for successful network authentication, ensuring the generated QR code works perfectly every time you need to share access.
