How to Create a QR Code for Free

QR codes are on menus, posters, packaging, and business cards because they do one thing brilliantly: turn a phone camera into a link. Making your own takes seconds, and a well-made code is reliable, on-brand, and — crucially — doesn't expire or depend on some third party staying in business.

What a QR code can hold

• A website link — the most common use, from posters to packaging.
• WiFi credentials — guests connect by scanning instead of typing a password.
• Contact details — scan to save a phone number or full contact card.
• Email, phone, or SMS — kick off a message with one scan.

Making it reliably scannable

A QR code needs enough contrast (dark code on a light background works best), a quiet margin around it, and enough size for the scanning distance — a code on a billboard must be far bigger than one on a business card. Higher error-correction levels let the code still scan even if part of it is smudged or covered, which is what makes adding a center logo possible.

Static codes don't expire

A static QR code encodes the destination directly, so it works forever and isn't tied to any service that might shut down or start charging. Generate it in your browser, download it as a PNG or SVG, and use it anywhere — print or screen.
