Multi-Format QR Code Creation
This free online QR Code Generator allows you to instantly produce custom barcodes for links, local Wi-Fi networks, WhatsApp chats, emails, and social media channels. Designed for absolute privacy and execution speed, all encoding operations are calculated locally inside your web browser. This means your personal details, network passphrases, email templates, and numbers are never sent to external servers or logged. Because it does not rely on heavy dynamic script libraries or server processing, pages load instantly on any device. Supported modes format data blocks according to standard device connection rules. Pointing any native iOS or Android camera at the generated patterns automatically initiates connections, opens URLs, prepares messages, or loads profiles.

Frequently Asked Questions
Do QR codes generated here expire?
No. These QR codes are static, containing standard configuration strings that are parsed locally by modern scanning devices. They will remain functional indefinitely as long as your targets (URLs, phone numbers, or passwords) do not change.
How does the WhatsApp QR Code work?
It creates a standardized wa.me URL containing the recipient's phone number and message. When scanned, the WhatsApp app launches a direct chat window on the user's phone, containing your pre-filled message.
Can I use the URL tab for videos or images?
Yes. Simply paste the link to your hosted video (e.g., YouTube, Vimeo) or hosted image into the URL field. When scanned, the target device's web browser will open the media page directly.
What is the purpose of the Error Correction level?
Error Correction (Reed-Solomon) allows the QR pattern to remain readable even if it is partially covered, scratched, or dirty. High error correction levels (H) can recover up to 30% of lost data but result in a slightly more complex and dense visual pattern.
Are my Wi-Fi credentials or phone numbers stored?
No. Everything runs inside your browser using raw, in-memory script modules. You can even generate your custom codes while offline by disabling your internet connection entirely.
