A QR Code Generator is a specialized software tool that encodes text, web links, network credentials, and structured contact information into a two-dimensional Quick Response barcode matrix.
Unlike traditional 1D barcodes that only store numbers horizontally along a single axis, QR codes store data both horizontally and vertically. This allows them to hold hundreds of times more data in a compact, camera-readable square.
Standard QR codes adhere to the ISO/IEC 18004 international specification. The matrix consists of:
QR codes incorporate Reed-Solomon error correction polynomials to restore corrupted or obscured data:
Encodes standard HTTP and HTTPS web addresses. Pointing a phone camera automatically opens mobile browsers like Safari, Chrome, or Firefox directly to your landing page.
Uses the standard WIFI:T:WPA;S:...;P:...;; payload. Allows guests in cafes, hotels, and offices to join your encrypted wireless network with a single tap.
Converts personal and business details into an electronic vCard 3.0. Scanning immediately prompts the smartphone address book to create or update contact records.
Many online QR generators route your links and passwords through intermediate tracking servers or shorten them into dynamic redirects that can expire or leak data.
Todoal’s QR Code Generator runs 100% locally in your browser memory. We do not store, intercept, or upload your WiFi credentials, telephone numbers, or vCard information.

Common questions about creating, customizing, and printing QR codes.
A QR code generator is an online utility that converts digital information—such as website links, WiFi credentials, contact cards (vCards), or plain text—into a 2D matrix barcode that can be scanned by smartphone cameras and dedicated barcode readers.
Yes, this QR code generator is 100% free with no account requirements, no scan limits, no watermarks, and no subscription fees.
Yes. Select the URL tab, paste or type your web address (such as example.com or https://example.com), and the generator will normalize and validate the URL to produce an instantly scannable QR code.
Yes. Choose the WiFi tab, enter your network name (SSID), password, and security encryption type (WPA/WPA2/WPA3, WEP, or None). When scanned by a phone camera, devices can connect automatically without typing passwords manually.
Yes. You can export high-resolution raster PNG images in multiple resolutions up to 2048px, ideal for websites, digital displays, and crisp printed flyers.
Yes. The tool generates pure vector SVG files that scale infinitely without pixelation or loss of clarity, making them perfect for graphic design software, billboards, and large-format printing.
No. The entire encoding and rendering process runs 100% locally inside your browser using pure JavaScript and HTML5 Canvas. Your WiFi passwords, contact details, and URLs never touch an external server.
Level M (15% redundancy) is recommended for general website and text usage. If you anticipate your printed QR code might experience minor smudges, physical wear, or outdoor exposure, choose Level Q (25%) or Level H (30%).
