Generate QR codes for URLs, text, WiFi
Built & maintained by Pappu Venkata Subbi Reddy, founder of Clacify
The QR Code Generator turns any text, URL, phone number, email, Wi-Fi credential, or UPI payment link into a scannable QR code you can download as an image or SVG. Type your content, pick a style, set a solid or gradient colour, optionally drop your logo into the centre, and export a crisp file ready to print on a poster, business card, menu, or product label. QR codes have become ubiquitous in India — from UPI payments to restaurant menus to event check-ins — and this tool lets you create a branded one in seconds with no sign-up. Everything is generated in your browser, so the data you encode (which may include payment details or private links) is never sent to a server.
The tool encodes your input using the QR code standard (ISO/IEC 18004), which arranges the data into a matrix of black and white modules with built-in Reed-Solomon error correction so the code still scans even if partly damaged, printed small, or partly covered by a logo. It selects an appropriate version (matrix size) for your data length and error-correction level, then renders the matrix to a canvas — applying your chosen foreground colour or gradient before export — and offers both PNG (for direct printing) and SVG (for lossless resizing in design software) output. Larger payloads produce denser codes, so keeping the encoded URL short yields the cleanest, most reliably scannable result. The QR image is created entirely in your browser with no server round trip.
QR codes are built with redundancy on purpose. The Reed-Solomon error correction baked into the standard means a QR code can lose a meaningful percentage of its modules — up to roughly 30% at the highest correction level — and still decode correctly, which is exactly what makes overlaying a small logo in the centre safe: scanners simply reconstruct the handful of modules the logo covers from the surrounding redundant data. This is the same property that lets a QR code keep working when it is printed on a curved coffee cup, partially smudged, or photographed at an angle. It is not unlimited, though — a logo that is too large, or a foreground/background colour combination with too little contrast, can push a code past what error correction can recover, which is why keeping the logo modest and the colours reasonably contrasted matters more than the code's raw resolution.
PNG is a fixed-resolution raster image — perfect for immediately dropping into a WhatsApp message, a slide deck, or a webpage, but it will look blurry or pixelated if you stretch it far beyond its generated size. SVG is vector data — mathematically defined shapes rather than pixels — so it scales to any size, from a business card to a building banner, with zero loss of sharpness. The practical rule: use PNG for digital/quick use, and use SVG whenever the code is headed to a professional printer or a large-format poster, since a print shop can scale an SVG cleanly to whatever dimensions the job needs.
A UPI payment QR code is just a QR code encoding a specially formatted upi:// URI containing the payee's UPI ID, name, and optionally a fixed amount — any UPI app reads that URI the same way it reads one generated by a bank or PhonePe/GPay. Because this tool encodes whatever text you give it, pasting a correctly formatted UPI URI produces a working payment code, though for accepting real payments most small businesses are better served by the QR code their bank or payment app issues directly, since those are tied to a verified merchant account. Where this tool is genuinely useful for India-specific cases is menus (encode a Google Drive or website link to a digital menu), event check-ins (encode a registration or contact-sharing link), and Wi-Fi sharing (encode a WIFI:S:<ssid>;T:WPA;P:<password>;; string so guests connect with one scan instead of typing a password).
Open Clacify's QR Code Generator, select URL mode, paste your website link, and click Generate. A scannable QR code appears instantly — download it as PNG and use it in print materials, social media, or any digital platform.
Yes. Type the WiFi connection string into Clacify's QR Code Generator in the standard format WIFI:T:WPA;S:YourNetworkName;P:YourPassword;; (replace the network name and password) and click Generate. Anyone who scans the resulting code with a smartphone camera connects to your WiFi automatically — no need to type the password.
