QR Code Generator

A QR code for a link, Wi-Fi or a business card.

Free, no sign-up, and it lasts

Many generators create a “dynamic” code that points at their own server, which then forwards to your address. When the trial ends the code stops working, and the business cards you printed become waste paper.

Ours

Static code

The address is encoded into the image itself. The code works forever and depends on no service.

  • Generated in your browser
  • Nothing is sent to a server
  • Will not expire in a month
vs
Others

Dynamic code

The code points at someone else’s server, which forwards onward. Handy for statistics, risky for print.

  • Stops working without payment
  • Depends on a third-party service
  • An extra hop when scanned

What size to print

A simple rule: the side of the code should be about one tenth of the distance it will be scanned from.

Business card, label from 2×2 cm — scanned at arm’s length
Flyer, menu from 3×3 cm — easy to pick up and hold a phone to
Poster, stand from 10×10 cm — scanned from one or two metres
Shop window, billboard from 30×30 cm — three metres and beyond, per the rule above

Why a QR code will not scan

No quiet zone around it The code needs a clear margin about four of its own modules wide. Without it the camera cannot find the edges.
Printed too small The most common cause on printed material. Check against the table above.
Poor contrast Light grey on white, or colour on colour, defeats most cameras. Black on white is the safe choice.
The link is too long More characters mean smaller modules. Shorten a long tagged URL before encoding it.
Curved or glossy surface Gloss creates glare and a curve distorts the grid. For bottle and jar labels use matte stock and a larger size.

Before printing a run, test the code on two different phones — and in exactly the form it will be produced. Decode an existing QR code.

Create a QR code for free

Paste a link, text, phone number or any data — the QR code generates instantly right in the browser. Adjust the size with the slider and download a ready PNG for print or publishing. No sign-ups, watermarks or limits: the code is static, so it will work forever and free.

Where to use it: a website or Instagram link on a business card, a venue menu on the table, guest Wi-Fi, a payment link, a greeting card with a surprise. For print keep the physical code size at least 2×2 cm and leave white margins around — then cameras read it on the first try.

FAQ

How to create a QR code?
Paste a link or text into the field — the QR code generates automatically. Choose a size and click "Download PNG" to save the image.
Are QR codes free and permanent?
Yes. A generated static QR code works forever and free — it contains the data directly, without intermediaries or subscriptions.
What QR size to choose for print?
240px is enough for a business card; for a poster or sign use a larger size. The key rule — the QR should be at least 2 cm in real size.
Can I change the link after printing?
No, in a static QR the data is embedded inside. If the link may change, use a dynamic QR via special services.
