Create QR codes online for free. Encode links, Wi-Fi passwords, contact cards and text into scannable codes in just a few seconds.

QR codes are everywhere: restaurant menus, event tickets, Wi-Fi passwords, product packaging. They pack a link or a chunk of information into a pattern any phone camera can read in a second. A free online QR code generator lets you create your own in less time than it takes to type this sentence. Small businesses use them to collect reviews, teachers share resources with a scan, and event organisers skip paper tickets entirely.

h2>What you can put in a QR code

• Website links: the classic use — point straight at a page.
• Wi-Fi credentials: guests join your network without typing a password.
• Contact cards: share your details with one scan.
• Plain text: short messages, coupons or instructions.
• App links: send people directly to a download page.
• Payment details: many payment apps let customers pay by scanning your code at the till.

How to create a QR code online

1. Open the generator and choose the content type.
2. Enter your link, text or details carefully — a typo becomes permanent once printed.
3. Customise colours or style if the tool allows, keeping contrast high.
4. Generate, then scan it with your own phone before sharing.

Making codes that actually scan

• Contrast is king: dark codes on light backgrounds scan best. Fancy low-contrast designs look nice and fail often.
• Size matters in print: a code on a business card needs to be at least 2 cm across; billboards need much more.
• Test in real conditions: scan from the distance people will actually use, in similar lighting.
• Shorten long links: less data means a simpler pattern that scans faster and works at smaller sizes.

Common mistakes

Skipping the test scan: always verify with at least two different phones before printing hundreds of flyers.

Linking to temporary pages: QR codes on printed material live for years. Point them at stable URLs you control.

Frequently asked questions

Do QR codes expire?

The pattern itself never expires, but the link inside can break if the destination page disappears.

Can I track scans?

Only if you route the code through a link-tracking service first. A plain QR code has no analytics.

Are QR codes safe?

They can link anywhere, so only scan codes from sources you trust.

What image format should I download?

PNG works well for print. If you need exact dimensions, resize the exported image afterwards.

Conclusion

QR codes bridge the physical and digital worlds in a single scan. Keep the design high-contrast, test before you print, link to stable pages, and they will just work — on menus, packaging, posters and anywhere else a link needs to escape the screen.
