QR Code Generator

QR codes are the easiest way to bridge the physical and digital worlds — print one on a business card, a poster, or a product, and anyone with a phone can scan it instantly. This generator covers the four most-used QR content types: plain text or URL, Wi-Fi credentials (so guests can join your network with one scan), vCard (contact information that imports directly to a phone's address book), and mailto links (pre-fill a recipient, subject, and body).

You can tune all the parameters that matter: size in pixels, error correction level (higher levels make the code more tolerant of damage and partial occlusion, useful if you'll print at small sizes or add a logo), and custom foreground/background colors for branding. Output is available as PNG (a raster image) or SVG (infinitely scalable, perfect for print). The QR code is generated entirely in your browser using the `qrcode` library — no data is uploaded.
