Question 1

What types of QR codes can I generate?

Accepted Answer

You can generate QR codes for URLs/links, plain text, SMS messages, email addresses, and phone numbers. Each type encodes the data so scanners automatically perform the right action (open link, send SMS, call, etc.).

Question 2

What error correction level should I use?

Accepted Answer

L (7%) is fine for clean digital display. M (15%) is the default and works well for most uses. Q (25%) and H (30%) are recommended if you plan to print the QR code or add a logo overlay, as they allow the code to be scanned even if partially damaged.

Question 3

Can I customize the QR code colors?

Accepted Answer

Yes. You can set custom foreground and background colors. For best scannability, use dark foreground on light background (high contrast). Avoid inverting colors as some scanners cannot read inverted QR codes.

Question 4

How do I download the QR code?

Accepted Answer

Click the Download PNG button for a high-resolution image, or Download SVG for a vector format that scales without quality loss. SVG is recommended for printing.
