How It Works
QR codes store data as a grid of dark and light modules. This generator uses the Reed-Solomon error-correction algorithm (level M, which tolerates up to 15 % damage) to encode your text into a binary matrix. The matrix is then rendered as a scalable SVG image — a vector format that prints crisply at any resolution. The four quiet-zone modules of white space on every side are required by the QR specification so that scanners can locate the code boundary. Module count grows in discrete 'versions' as the encoded string gets longer; a typical short URL fits comfortably in a Version 3 (29 × 29) or Version 4 (33 × 33) code.
Examples
Website Link
Generating a QR code for a homepage URL at 300 px.
Result: A 300 × 300 px SVG QR code is produced that links to https://bettercalculators.net.
Large Print Code
Bumping the size to 600 px for a poster or business card print.
Result: A 600 × 600 px SVG QR code is produced — same data, larger display size, no loss of quality.
Frequently Asked Questions
Is my data sent to a server?
No. The QR code is generated entirely inside your browser using JavaScript. No text or URL you enter leaves your device, so this tool is safe to use with private links or internal company URLs.
What format is the generated QR code?
The code is produced as an SVG (Scalable Vector Graphics) image. SVG is resolution-independent, meaning it looks sharp whether you display it at 100 px on screen or print it at full poster size. You can right-click the image to save it or copy it.
How much text can a QR code hold?
A standard QR code can hold up to about 4,296 alphanumeric characters at error-correction level M. Shorter inputs produce smaller, easier-to-scan codes. For best scan reliability, keep URLs short — using a link shortener if necessary.
