QR Code Generator: Create Free Custom QR Codes Online
QR codes have become one of the simplest bridges between the physical and digital worlds. Scan a QR code on a restaurant menu, a product box, a flyer or a business card and your phone instantly opens a URL, joins a Wi-Fi network, saves a contact, or triggers a payment. Sigify's QR Code Generator lets you build fully custom QR codes for any of these scenarios โ for free, in your browser, with no signup.
What is a QR Code?
A QR (Quick Response) code is a two-dimensional barcode invented in 1994 by Denso Wave, a subsidiary of Toyota. Unlike a traditional barcode that stores data in a single line, a QR code stores data in both horizontal and vertical patterns of black squares on a white background. The patterns encode up to several thousand alphanumeric characters and include error-correction data so the code remains scannable even when scratched, dirty or partially obscured.
Static vs Dynamic QR Codes
Sigify creates static QR codes. The data is encoded directly into the image โ once printed or shared, it works forever with no backend or expiry. There is no analytics dashboard, no scan counter and no monthly fee. For most everyday uses โ business cards, menus, brochures, packaging, posters โ static is the right choice.
Dynamic QR codes (offered by some other services) store a short URL in the image and forward to a target you can change later. They cost subscription money and create a privacy dependency. With Sigify you control the data directly and the code never breaks.

Why Sigify's QR Code Generator?
Sigify is privacy-first and browser-first. Everything happens on your device โ the QR code is generated locally, your data is never sent to a server, and you can use the tool offline once it has loaded. You can produce unlimited QR codes with unlimited scans for personal or commercial projects.
Customize the QR code by changing foreground and background colors, adding an optional logo, choosing between square, rounded or dot module styles, and picking the appropriate error-correction level (the higher the correction, the larger the code, but the more reliably it scans when damaged or carrying a logo).
How to Use Your QR Code
- Print: Export as SVG for crisp, infinite-resolution print on business cards, posters and packaging.
- Web / Social: Export as 256 px or 512 px PNG for sharing on Instagram, LinkedIn, email campaigns and websites.
- Documents: Drop the SVG into a Word, Google Docs or PowerPoint file as a vector that will never pixelate.
- Scan test: Use any smartphone camera or QR scanner app to verify the code before publishing.
