Frequently Asked Questions

What can I encode in a QR code?

QR codes can encode URLs, plain text, phone numbers (use 'tel:+15551234567'), email addresses (use 'mailto:'), SMS messages, Wi-Fi credentials, vCard contacts, and more.

What image format is downloaded?

QR codes are downloaded as PNG files, which are suitable for both digital use and print. PNG supports sharp edges at any resolution, making it the ideal format for QR codes.

Are generated QR codes stored on your server?

No. QR codes are generated entirely in your browser. Nothing is stored or transmitted to any server.

How much data can a QR code hold?

A standard QR code can hold up to 3,000 alphanumeric characters or 7,089 digits, but shorter content produces simpler QR codes that scan faster and more reliably. URLs should ideally be under 300 characters.
