QR Code Generator
Generate a QR code from any URL, text, or message instantly. Free and downloadable.
Overview
Generate a scannable QR code from any URL, plain text, phone number, email address, or structured data string. QR codes are machine-readable optical labels that cameras and scanner apps can decode in milliseconds. They are used in product packaging, business cards, menus, marketing materials, event tickets, and contactless information sharing.
Common use cases
- Create a scannable link to a website or landing page for print materials.
- Share Wi-Fi credentials via QR code on a printed card.
- Generate a QR code for a contact vCard or phone number.
- Add a QR code to event tickets for fast gate scanning.
Examples and notes
- Paste a URL like https://tooler.live to generate a scannable web link QR code.
- Type 'WIFI:S:MyNetwork;T:WPA;P:MyPassword;;' to create a Wi-Fi credentials QR.
- A vCard string generates a QR code that adds a contact when scanned.
Important note
QR code capacity is limited. Very long strings may produce dense codes that are harder to scan under poor lighting or with low-resolution cameras. Keep input concise, especially for print use.
Frequently Asked Questions
What can I encode in a QR code?
URLs, plain text, email addresses, phone numbers, Wi-Fi credentials, vCard contacts, or any short structured string. Keep content concise for easier scanning.
Can I download the QR code?
Yes. Right-click the generated SVG image and save it. You can then paste or print it on any material.
What is the maximum content length for a QR code?
QR codes can technically encode up to 4,296 alphanumeric characters, but very long content produces dense patterns that are harder to scan. Keep input under 200 characters for reliable print use.
What format is the generated QR code?
The QR code is generated as SVG, which is infinitely scalable and suitable for both digital use and high-resolution print output.
