How to make your QR Code

Any Website, Blog, Social Media, App...

Use the complete web address.

Type or paste it into our QR Code Generator and test it before printing.

Example: https://jwbiz.com/ but replace with the one you want to use.

Major Benefit: A Dynamic QR Code will point to a web page, meaning the content of that web page can easily be changed.

Change the sections in red bold text for your own case-sensitive credentials.

Copy and paste the one you want into a document. Take care not to remove any of the : or ; characters or it won't work.

When you have made the changes, copy and paste into our QR Code Generator and test it.


WPA

If your Connection Security Type is WPA2 or WPA3 do include the digit - just use WPA as detailed below.

WIFI:S:your-ssid;T:WPA;P:your-password;;


WEP

WIFI:S:your-ssid;T:WEP;P:your-password;;


Tip: There is no real need to print on paper - just keep the code in your phone, and others can scan it to join your network from there.

You can make a Static QR Code for many uses.

However, once you have printed it or used it on the web, you will never be able to change the content it points to.

For example, you could make a vCard, but if you ever had to change details, such as your address or phone number, it would be nothing other than totally useless!


The best solution is to always use Dynamic QR Codes that can have the content they point to very easily updated.

A QR code minimum size should be 2.2 cm so that modern devices can decode them. For business cards try 76px x 76px but measure them first.
