What is the QR code generator?

A QR code, or Quick Response Code, is a two-dimensional barcode that stores information in a square grid pattern. A smartphone camera can scan it to open a website, save a contact, connect to Wi-Fi, show text, or start other actions.

This tool creates QR codes directly in the browser for URLs, plain text, email, phone numbers, and other data. It supports real-time preview, high-resolution PNG download, foreground and background color customization, and local-only processing.

Use cases and setup

Marketing, store, and personal use

Business cards can link to a portfolio site or LinkedIn profile.
Flyers and posters can link to event pages or coupon downloads.
Product packaging can link to how-to videos or authenticity checks.
Stores can use QR codes for Wi-Fi connection, smart ordering, waitlist registration, menus, payment, or feedback surveys.
Personal use includes invitations, maps, study materials, lost-item tags, pet tags, and hidden messages.

Scanning reliability

Enter the full URL including https:// when encoding a website address.
Use strong brightness contrast between foreground and background colors, especially when applying brand colors.
For print, use at least 2 cm x 2 cm size in the source recommendation.
Leave enough quiet zone margin around the code and avoid overlapping nearby design elements.
Long URLs make QR patterns more complex, so a short URL can improve scan reliability.
Always test the downloaded PNG with a smartphone camera before printing or publishing.

Privacy and permanence

Static QR behavior

A QR code generated by this tool has no built-in expiration date; the encoded data is inside the pattern itself.
The code stops being useful only if the encoded destination, such as a website URL, disappears or changes.
The generated codes are 100% free for personal and commercial use in the source FAQ.
Input data is processed with browser JavaScript and is not stored or sent to a server.
