QR codes that connect the physical world to your digital content

A QR code is a bridge between something physical — a business card, a poster, a product label, a restaurant table — and something digital — a website, a WiFi network, a vCard, a payment link. The code itself is just a pattern of black and white squares that a phone camera decodes in a fraction of a second. What you put behind that pattern determines its value. Chaudify's QR tools let you create that pattern for any destination, with full styling control and no signup.

URL QR codes are the most common — scan to open a webpage. But the use cases within that are surprisingly varied: a restaurant menu QR on a table, a LinkedIn profile QR on a conference badge, a product page QR on packaging, a WiFi QR for a cafe so guests don't ask for the password, an app-store QR on a flyer to drive installs, a portfolio QR at a networking event. Each one has slightly different design needs — a menu QR benefits from brand colors, a WiFi QR needs to be large enough to scan from a wall, a business card QR should be small and elegant. Our URL QR tool covers all of these with presets and styling options.

WiFi QR codes solve a specific pain: sharing a network without dictating the password out loud or typing it into someone's phone. A scanned WiFi QR connects the device directly — SSID, password, and encryption type all encoded. For cafes, offices, Airbnbs, and events, that's a better guest experience and fewer typos. Our WiFi QR tool supports WPA/WPA2, WEP, and open networks, with size presets and styling so the code matches your venue.

Email, phone, and text QR codes encode contact information directly — scan to add a vCard or dial a number. These are ideal for business cards, name badges, and print materials where you want someone to save your contact or call you immediately. Our email QR, phone QR, and text QR tools generate these in multiple formats and sizes.

Styling matters because a generic black-and-white QR on a white business card looks like a mistake, not a design choice. Our tools let you set dot color, corner color, background color, gradients, dot style (dots, rounded, classy, square), and logo placement in the center. High error correction keeps the code scannable even with a logo in the middle or colors that reduce contrast. Download as PNG, SVG, JPEG, or PDF depending on whether you need transparency, infinite scaling, or print-ready output.
