QR Code Generator

Generate downloadable QR codes from plain text, URLs, vCard contact cards, or Wi-Fi credentials. Uses the qrcode library with fixed settings: 300x300px output, errorCorrectionLevel M, and a margin of 2 modules. Encoding is fully client-side.

1. Pick a tab: Text/URL, vCard, or WiFi. 2. For Text/URL, type the content and press Enter or click Generate. 3. For vCard, fill in any of first name, last name, phone, email, organization, job title, and website, then Generate (Copy vCard copies the raw VCARD text). 4. For WiFi, enter SSID (required), password, encryption, and hidden-network flag, then Generate. 5. Click Download PNG to save the 300x300 image.

WiFi strings follow the WIFI:T:<enc>;S:<ssid>;P:<pass>;H:<hidden>;; format with WPA/WPA2, WEP, or nopass encryption; special characters in SSID/password are backslash-escaped. vCard output is VERSION:3.0 with FN/N/TEL/EMAIL/ORG/TITLE/URL fields. Error correction is fixed at level M (~15% recovery). Input exceeding the encoder capacity shows a "text too long" error and no image is produced.
