A QR code is a two dimensional code that allows users to store specific information in black and white. It is essentially used with products and is unique for each one of them. The Free QR Code Generator allows users to create such codes in different colours and can contain any alphanumeric data. Some of these include text, birthdays, specific numbers, email addresses, URLs, etc. Once the software is downloaded and installed onto a device running on any Windows OS, users are given a choice to enter the data as per their requirements and a unique code is generated which can be used for any purposes. Saving it and using it as a logo, getting it printed on a T shirt and other accessories are some of the most common reasons for users to get the Free QR Code Generator. Though it sounds very complex, it is actually very easy to generate such codes. The interface of the software contains a space in which users need to type their text, number, etc. As soon as the user starts doing this, the window on the right side of the interface starts generating the code. It can be as specific as a logo for a group or company or as trivial as an SMS. Users can customize the pixel size, the level of transparency and also the error correction level. When the code is ready, it can be saved in JPG, PNG and a few other formats so as to print the same at a later stage. The Free QR Code Generator also allows the code to be changed, should there be a necessity. For all those who are using the freeware for professional reasons, this feature can prove to be quite handy should there be any mistakes in the previous one.
