Base64 Encoder/Decoder

Base64 Encoder/Decoder is a lightweight and portable software application that enables you to seamlessly encode and decode files to and from Base64, as the name implies.
It can be used to securely transmit data over the Internet, for example. The tool comes equipped with just a few standard options that can be seamlessly configured by all user levels.
Since installation is not a prerequisite, you can drop the executable file anywhere on the hard disk and just click it to run.
It is also possible to save Base64 Encoder/Decoder to a USB flash disk or similar storage unit, in order to run it on any computer easily, as long as it has .NET Framework installed.
Plus, the Windows registry does not get updated with new entries, and no additional files are created on the HDD without the user's consent.
The interface is represented by a simple window with a clean structure, where the "what you see is what you get" concept clearly applies, as there are no other options available, aside from the ones visible in the main frame.
Selecting a file is possible through the file browser, since drag-and-drop is not supported. All you have to do is specify the output directory and file name, and specify the action between encoding to Base64, and decoding. Note that User Account Control (UAC) must be deactivated, and files with the same name are automatically overwritten (this option cannot be changed).
Unfortunately, the tool failed to deliver accurate results during our tests. Decoding a previous encoded file did not result in matching content. We must also take into account that Base64 Encoder/Decoder has not been updated for a long time, and it may not be fully compatible with newer operating systems. Users should look for more powerful applications.
