The Technical Details
Quick Response (QR) codes are two-dimensional matrix barcodes invented in 1994 by Denso Wave. They store data using a grid of black squares on a white background, which can be scanned by camera devices. QR codes utilize Reed-Solomon error correction, allowing them to remain completely readable even if up to 30% of the barcode is damaged, dirty, or obscured. This error correction capability makes them ideal for physical world applications like menus, ticketing, and product labeling.
Unlike traditional 1D barcodes that read horizontally, 2D QR codes store data both vertically and horizontally. This allows them to hold hundreds of times more data—up to 4,296 alphanumeric characters. Our generator builds these vector grids locally using modern canvas APIs, meaning all matrix rendering, rendering overlays, and file formatting happen immediately on your CPU without server latency.
Frequently Asked Questions
What do the error correction levels (L, M, Q, H) mean?
Error correction levels determine how much of the QR code can be damaged or covered while still remaining scanable. Level L corrects up to 7% damage, Level M up to 15%, Level Q up to 25%, and Level H up to 30%. Higher levels increase the density of the pattern.
Should I download PNG or SVG?
Download PNG if you need a standard image for websites, emails, or social media. Download SVG if you plan to print the QR code on physical materials like business cards or banners, as vector SVGs can be scaled to any size without losing crispness.
Is this QR code generator free and safe to use?
Yes! Our generator is 100% free and runs entirely inside your web browser. No registration is required, no analytics track your data, and your inputs are processed completely offline for absolute privacy.
Can I embed a logo inside the QR code?
Yes! By setting your error correction level to 'H' (High, up to 30% damage tolerance), you can safely superimpose a small logo in the exact center of the QR code using any image editor, and scanners will still read the code perfectly.
Why is my QR code too dense or hard to scan?
The density of a QR code increases with the length of the text encoded. To keep the pattern simple and easily scannable, we recommend using short URLs or a URL shortener service for long web addresses.
Do QR codes expire?
No, static QR codes never expire because the data is encoded directly into the pattern itself. As long as the URL or text inside is valid, the QR code remains active indefinitely.
