Create a QR code for a website, vCard business card, email, phone, or text. Customize colors, size, and error correction level, then download a ready PNG or SVG file.
For printed materials, we recommend a minimum size of 300px and error correction level H.

Enter data to generate a QR code.
A QR code (Quick Response) is a two-dimensional barcode that can be scanned with a smartphone camera. Unlike traditional barcodes, QR codes store data both horizontally and vertically, allowing them to encode significantly more information - up to approximately 3,000 alphanumeric characters.
The QR code was developed in 1994 by the Japanese company Denso Wave (part of the Toyota group) for tracking car parts. Today, QR codes are widely used in marketing, hospitality, logistics, and business communication. They gained particular popularity during the COVID-19 pandemic, when restaurants began replacing paper menus with QR codes.
Creating a QR code takes just a few seconds:
The free QR code generator supports five data types - each useful in different situations:
Knowing the technical parameters helps create QR codes that are readable in all conditions:
QR codes find use in many industries and scenarios:
The generator lets you customize several parameters affecting the appearance and readability of the code:
Tip: Maintain high contrast between the code and background (minimum 3:1). A dark code on a light background scans most easily.
Error correction is a mechanism that enables reading a QR code even when part of it is damaged, dirty, or obscured. The generator uses the Reed-Solomon algorithm, a standard in QR codes.
Note: A higher correction level means a larger and more complex code. With large amounts of data and level H, the code can become very dense.
