QR Code Generator
Generate a crisp QR code for any link or text in seconds. Choose the size and foreground color, then download a PNG that scans reliably from screens and print. Everything runs in your browser — nothing is uploaded.
What this means
A QR code is a square of black-and-white modules a phone camera can read in a fraction of a second. It can hold a URL, plain text, Wi-Fi credentials or contact details.
How we calculate it
Formula
QR encodes your data into a matrix using Reed–Solomon error correction, scaled to the size you choose.Worked example
Turn your website URL into a QR code for a poster.
- 1Paste your URL into the text field.
- 2Choose the size and color.
- 3Download the PNG and add it to your design.
Important assumptions
- Very long text needs a larger QR to stay scannable.
