Will the QR code still scan if I customize the colors?

Yes, as long as there's enough contrast between the foreground and background colors — dark foreground on a light background is always the most reliably scanned.

What is the difference between PNG and SVG downloads?

PNG is a raster image ideal for websites and social media; SVG is a scalable vector format that can be enlarged to any size without pixelation, making it perfect for billboards, posters, and print media.

Is my encoded content uploaded to any server?

No. The entire QR code generation takes place locally inside your browser. No URLs, Wi-Fi passwords, or contact details are ever uploaded or stored.

How does the Wi-Fi QR code work?

When scanned with a mobile camera, the device automatically prompts the user to join the Wi-Fi network without manually typing the password.

Which error correction level should I choose?

Use Medium (15%) for everyday digital or small print use; use High (30%) if you intend to place a logo in the center or print on curved or outdoor surfaces.

Understanding the QR Code Generator

QR Code Generator creates customizable, high-resolution Quick Response (QR) matrix barcodes for URLs, Wi-Fi credentials, vCard contact cards, email messages, phone numbers, and plain text with customizable colors, brand logos, and error correction levels.

How It Works

Select content type (URL, Wi-Fi, vCard Contact, Text, Email, SMS).
Enter your payload data in the input fields.
Customize colors (foreground and background), dot styling, and upload an optional center brand logo.
Select Error Correction Level (Low, Medium, Quartile, High) and download in PNG or vector SVG format.

How to Get the Best Results

Error Correction with Logos: When placing a logo in the center of a QR code, always select Level H (High / 30% recovery) so the code remains 100% scannable.
High Contrast Rule: Ensure high contrast between the dark foreground modules and light background — dark codes on white backgrounds scan most reliably.
Vector SVG for Print: Download in scalable SVG format when printing QR codes on banners, posters, and business cards for crisp lines at any size.
