QR codes are everywhere now — on menus, business cards, flyers, product packaging, and event posters. They're just a fast way to send someone from the physical world to a digital one: point a phone camera, tap the notification, done. The best part is you can make your own in under a minute, for free, without installing anything.
What a QR code can hold
A QR code is really just an image that encodes a bit of data. The most common types:
- A website URL — the classic "scan to visit."
- Plain text — a message, a code, instructions.
- Wi-Fi credentials — guests scan to join your network without typing the password.
- Contact info (vCard) — scan to save your details straight into contacts.
- Email or phone — scan to start a message or call.
For 95% of people, it's the URL type: you have a link, you want a code that opens it.
How to make one
- Decide what the code should do (usually: open a link).
- Paste your URL into a QR generator.
- Download the image — PNG for screens, SVG if you'll print it large (SVG stays sharp at any size).
- Test it with your own phone before you print or publish it.
That last step matters. Printing a thousand flyers with a broken code is a bad day. Always scan your own code first.
Tips for codes that actually scan
- Keep good contrast. Dark code on a light background scans best. Low-contrast color combos can fail.
- Don't shrink it too small. On print, aim for at least 2 x 2 cm; bigger if people scan from a distance.
- Leave the quiet zone. That white margin around the code isn't wasted space — scanners need it.
- Use a short URL when you can. Less data means a simpler, more reliable code.

The bottom line
A QR code is a scannable shortcut to any link or bit of text. Paste your URL, download the image (PNG for screens, SVG for print), and — most importantly — test it on your own phone before it goes live. That's the whole process.
