How do I make a QR code for an ethereum address?

Question

I am not super familiar with QR codes.

Is there a piece of open source software I can use o convert an address to a QR code?

Not a duplicate; QR codes have plenty of use cases outside paper wallets. — Mikko Ohtamaa, Apr 03 '17 at 10:41
I think I'm conflating "paper wallets" with "QR code". I imagine there are other forms of paper wallets which aren't QR codes. Duplicate removed. — Richard Horrocks, Apr 03 '17 at 10:48
In what context? Do you want to make you app or site display QR code or do you just need it for your own use one time? — Nicolas Massart, Apr 03 '17 at 12:12
It looks like myetherwallet is producing invalid codes. It should be ethereum:x0... I'm not sure what they are putting in their codes, but it's non standard. — NickJ, Jul 29 '18 at 19:16

Try this:

https://chart.googleapis.com/chart?chs=300x300&cht=qr&chl=0x8CCF9C4a7674D5784831b5E1237d9eC9Dddf9d7F&choe=UTF-8

Where:

chs=300x300 = size
cht=qr = type
chl=0x8CCF9C4a7674D5784831b5E1237d9eC9Dddf9d7F = eth address
choe=UTF-8 = encoding

Some people recommend prefixing this with a scheme – William Entriken Mar 12 '18 at 15:38
@FullDecent Not sure what you mean, so you have any reference for your comment? – DerekC Mar 16 '18 at 15:29
The api is now deprecated. – Boris D. Teoharov Jul 23 '18 at 11:37

I think the simplest way would be to copy your ETH address and paste it in the text field of this website.. http://www.qr-code-generator.com/

With the oficial Ethereum Wallet software you can do it, just need to go to the account and in the right side of the interfice view you have this option => "Show QR-code" click here and the program show you in the screen the QR code for this direccion account.

You can go to https://www.myetherwallet.com/#view-wallet-info and select 'View with Address Only', paste any address, and it'll spit out a QR code (along with some other info)

If you are using Javascript you can use this module (in nodejs or in browser)

Example :

<script src="node_modules/qrcode/build/qrcode.min.js"></script>
<canvas id="qrcodec"></canvas>


<script>
 qrcodelib.toCanvas(document.getElementById('qrcodec'), "your eth address", function (error) {
    if (error) console.error(error)
    console.log('qrcode successfully created');
  });


</script>

alternatively you can use this related module dedicated to Ethereum : https://www.npmjs.com/package/ethereum-qr-code
