QR code generator

Make a QR code for a link, a text or your Wi-Fi, and download it as a picture.

What the code opens

Without https:// at the start, it's added for you.

Your QR code shows here

Made on your device: what you type is never sent anywhere. Scan the code with your phone before you print it.

How to make a QR code

  1. Choose what the code opens: a Link, a Text or a Wi-Fi network.
  2. Type or paste it. The code appears beside the boxes (below them, on a phone) and changes as you type.
  3. Pick its colours if you like: black on white scans best.
  4. Press PNG or SVG to download it, then scan it with your phone to check it before you print or share it.

Everything happens in your browser: what you type, your Wi-Fi password included, is never sent to EasiFox or anyone else.

What a QR code can open

  • A link: the phone offers to open the page. Use it for a menu, a booking page, a form, a video or your social profile. If you type easifox.com, the code holds https://easifox.com, so phones know it’s a web address.
  • A text: the phone shows it, ready to copy. Use it for a short note, a code to type, an address or instructions.
  • Wi-Fi: the phone offers to join the network, with no password to type. Choose the security your router uses (most use WPA2 or WPA3) and tick The network is hidden if it doesn’t show in the list of networks.

An example

To let guests join your Wi-Fi, choose Wi-Fi and type:

Box What you type
Network name Home Wi-Fi
Password sunny-day-42
Security WPA, WPA2 or WPA3

The code holds WIFI:T:WPA;S:Home Wi-Fi;P:sunny-day-42;;, the format phones read, and is 29 by 29 squares. Pointed at it, the camera of an iPhone or an Android phone offers to join the network. Print it and put it where your guests can see it.

A link is smaller: easifox.com makes a code of 25 by 25 squares. The longer the text, the more squares, and the larger you need to print the code for phones to read it.

PNG or SVG?

  • PNG is a picture about 1,000 pixels wide: right for a document, a slide, an email or a social post.
  • SVG is drawn from lines rather than pixels, so it stays sharp at any size: right for a printer, a poster, a sign or a design app.

Both keep a blank edge of four squares around the code, as the QR code standard asks: phones need it to find the code.

Tips for codes that scan

  • Size: print it at least 2 cm (0.8 in) wide. For a code read from afar, count about one tenth of the distance: a poster read from 3 metres needs a code about 30 cm wide.
  • Contrast: dark squares on a light background. Light squares on a dark background don’t scan on every phone, and the tool warns you when your colours are too close.
  • Margin: keep the blank edge clear of text, pictures and folds.
  • Test: scan the printed code with two phones, from the distance people will use, before you print many.
  • Say what it does: a line next to it, like “Scan for the menu”, gets more scans than a code alone.

These codes use medium error correction: they still scan with about 15% of the squares hidden or damaged, a scratch or a smudge for example.

QR code generator: questions and answers

Do these QR codes expire?

No. The code holds your link, text or network itself, so it works for as long as what it holds does. Some sites make "dynamic" codes that go through a short link of their own, and those stop working when you stop paying; these never do.

Can I use the codes for my business?

Yes, for anything, printed or online, with no fee, no credit to give and no watermark on the picture.

Can I change the link after I print the code?

No. The link is written into the squares themselves, so a new link needs a new code. If you may change it later, point the code to a page of your own site that you can update or redirect.

Can I see how many people scanned my code?

Not from the code itself. For a link, add a tag your site's analytics reads, like ?utm_source=poster, and count the visits that carry it.

How much can one QR code hold?

Up to about 2,300 letters and numbers. Accented letters and emoji take more room, and long texts make dense codes that are hard to scan, so keep it short when you can.

Why won't my QR code scan?

Most often it's printed too small, its colours are too close, or something covers its blank edge. Print it larger, use dark squares on a light background, leave a margin around it, and check that a phone reads it before you print many.
