QR Code

Nine payload types: URL, current page URL, plain text, contact vCard, Wi-Fi network, email, phone number, SMS and WhatsApp chat. Four layouts: plain code, card with a caption, code and text side by side, or a badge with a rounded frame. Set the error correction level and drop your logo in the middle (use level H so it still scans), show the encoded value under the code, and offer a Download PNG button with your own file name. The code is drawn in the visitor's browser by a small script loaded from a public CDN, so nothing is stored on your server.
