Question 1

What can I encode in a QR code?

Accepted Answer

You can encode any text or URL — website links, contact details (vCard), Wi-Fi credentials, phone numbers, email addresses, plain text messages, or app deep links. QR codes can store up to around 4,000 characters depending on the error correction level and content type.

Question 2

What is error correction and which level should I choose?

Accepted Answer

Error correction allows QR codes to be read even if part of the code is damaged or obscured. Higher levels add more redundancy, making the QR code more robust but also larger. Use Low (L) for clean digital displays, Medium (M) for general use, Quartile (Q) for printed materials, and High (H) when the code may be partially covered (e.g. with a logo overlay).

Question 3

Can I use custom colors for my QR code?

Accepted Answer

Yes. Use the QR Color picker to set the dark module color and the Background picker to set the light module color. Make sure there is sufficient contrast between the two colors — low contrast QR codes may fail to scan. Black on white is always the safest combination.

Question 4

What download formats are available?

Accepted Answer

You can download your QR code as PNG (raster image, ready for web, email, or print at fixed resolution) or SVG (vector format that scales to any size without quality loss — ideal for large-format printing or use in design tools like Figma and Illustrator).

Question 5

Is the QR code generator free and does it require an account?

Accepted Answer

Yes, the QR Code Generator is completely free. No account, registration, or email address is required. QR codes are generated entirely in your browser using the open-source 'qrcode' library — no data is sent to any server.
