Choose a QR code generator (website or app).
Enter the content to encode (URL, text, contact info, Wi‑Fi credentials, etc.).
Select the QR type/format if prompted (typically “URL” or “Text”).
Set options if available (size, error correction level, colors, logo).
Generate the QR code.
Download the QR code image (PNG/SVG) or copy the SVG/PNG.
Test the QR code with a phone camera or QR scanner to confirm it works.
Print or publish the QR code at a readable size.
If needed, re-generate with a larger size or higher error correction for better scan reliability.
