What is a QR Code Generator?
A QR code generator turns a piece of content — a link, plain text, an email, a phone number, or WiFi credentials — into a scannable square barcode that any smartphone camera can read instantly. This tool builds the correctly formatted data string for each content type and renders it as a QR code entirely in your browser.
How to Use This QR Code Generator
- Choose a content type: URL, Plain Text, Email, Phone, or WiFi.

When Do You Need a QR Code Generator?
QR codes are useful on business cards, menus, flyers, packaging, storefront signage, and receipts — anywhere you want someone to jump straight to a link, save your contact details, or join your WiFi network without typing anything in.
Frequently Asked Questions
QR code file formats?
This tool exports QR codes as PNG, a lossless raster format that works well for both web display and print. PNG is the most widely supported format for QR codes across printers, scanners, and apps.
Error correction levels explained?
Error correction lets a QR code stay scannable even if part of it is damaged or obscured. Level L recovers about 7% of data, M about 15%, Q about 25%, and H about 30%. Higher levels add resilience but make the code denser.
Dynamic vs static QR codes?
Static QR codes encode the final content directly and can never be changed once printed. Dynamic QR codes point to a redirect URL you control, letting you update the destination later — but they typically require a third-party service to manage the redirect.
QR code best practices for print?
Use a high error correction level for printed materials, keep enough white space (quiet zone) around the code, test scans before mass printing, and avoid sizing the code below about 2x2 cm for typical phone camera distances.
