QR Code Generator—WiFi, vCard, Logo | DKL App por DKL App

DKL App QRCode Generator makes it simple to create polished QR codes directly from your browser popup. Built as a compact and easy-to-use tool, it helps you generate QR codes for common everyday uses without needing a separate website or external service. You can create codes for website links, WiFi credentials, vCard contact details, email messages, and SMS messages, all from one place. When opened on a webpage, the extension can automatically prefill the current tab’s URL, making it especially quick to turn a page into a scannable code.

The extension is designed to balance simplicity with useful customization. After choosing the type of QR code you want, the popup shows only the fields that are relevant to that format, which keeps the process clear and organized. Once your information is entered, you can preview the QR code and refine its appearance before saving it. Customization options include multiple output sizes, foreground and background color controls, and ready-made color presets for faster styling. You can also choose from several module styles such as square, rounded, dots, classy, classy rounded, and extra rounded, along with different corner styles to better match your preferred look.

For users who want a more branded result, the extension also supports adding an optional logo image in the center of the QR code. This can be helpful for business materials, handouts, contact sharing, or more visually distinctive codes. At the same time, the extension includes practical safeguards to help make codes easier to scan. It validates key input types such as URLs, email addresses, and phone numbers, checks WiFi password length requirements, and warns when selected foreground and background colors may create poor contrast. Character counters are also included for supported fields like URL, SMS message, and email body, helping you stay within suitable content limits.

The experience is interactive and efficient. After a QR code is first generated, the preview can automatically refresh as you continue changing form values or styling options, so you can quickly see the effect of each adjustment. When your code is ready, you can export it as PNG for standard image use or SVG for scalable graphics workflows. The extension also includes sharing features, with external share targets available for URL-based QR codes, while non-link content such as WiFi details, contact cards, email content, and SMS payloads are not sent to third-party sharing sites. On supported browsers, native sharing may also be available for the generated PNG image.

The popup includes light and dark theme support, and your theme choice is stored locally so the extension opens the way you prefer. A reset option is also available whenever you want to clear the current form, remove an uploaded logo, restore the default field view, reset counters, and start again. Based on the package contents, QR code generation happens locally inside the popup, with no indication of a remote backend or cloud processing.

How It Works:
1. Open the extension popup and choose the QR code type you want to create: URL, WiFi, vCard, Email, or SMS.
2. Enter the required information in the fields shown for that format.
3. Adjust optional settings such as size, colors, module style, corner style, and logo upload.
4. Generate the QR code and review the live preview, which can continue updating as you make changes.
5. Check any validation messages, character counters, or low-contrast warnings to improve readability.
6. Download the final QR code as PNG or SVG, or use the available sharing options for supported URL-based codes.

Privacy: - No personal data collected. Based on the package contents, QR generation runs locally in the popup, the selected theme is stored locally, and the active tab URL is only used to prefill the URL field when available. External sharing is limited to URL QR codes, helping prevent WiFi details, contact information, email content, and SMS data from being sent to third-party sharing sites.
