Frequently Asked Questions

What can I encode in a QR code?

QR codes can encode URLs, plain text, email addresses, phone numbers, SMS messages, WiFi network credentials (SSID + password), vCards, and more. URLs are the most common use case, letting anyone who scans the code go directly to your website or link.

How do I make a QR code for a WiFi network?

Select WiFi as the content type, enter your network name (SSID), password, and security type (WPA/WEP/none). The generated QR code, when scanned by a phone camera, will prompt the user to join your network automatically — no typing required.

Are QR codes permanent?

A static QR code encodes data permanently — the QR image itself doesn't expire. However, if you encode a URL, the QR code only works as long as that URL is live. If you need to change the destination without reprinting, consider a dynamic QR code service that uses a redirect URL.

How small can I print a QR code?

The minimum printable size depends on the density of the code. A simple short URL can print reliably at 2×2 cm (about 0.8 inches). More complex content generates denser codes that need to be larger. For reliable scanning, aim for at least 2.5 cm × 2.5 cm and use a high error correction level for printed materials.

Do I need an account to generate QR codes?

No. AllTools QR Code Generator is completely free with no account, no watermark, and no limit on how many codes you generate. Just create and download.
