Mime Tool

Mime Tool is a lightweight and portable application that gives you the possibility to encode and decode text and files using the MIME Base64 encoding methods. It's wrapped in a simple interface and features intuitive options for all users, not only those experienced with such software.

Intuitive interface for encoding and decoding text

The GUI is made from a single window split into two parts for inputting text and viewing results returned by the program. You can type or paste text to decode in the upper pane and view encoded results in the lower pane, or vice versa.

Enter text or load files

Text can be loaded from files by indicating an item using the file browser, whose contents are immediately displayed in the window. Data can be encoded or decoded with the click of a button, as well as encoded or decode to file, after specifying the saving directory, file name and extension.

Set the encoding method

Unfortunately, Mime Tool is not explicit concerning the supported file types, but we've noticed that it works with plain text documents. You can pick the encoding method between Unicode and ANSI, enable instant encoding to perform tasks automatically while typing characters, as well as select and copy text.

Portability advantages

The entire program's packed in a single .exe file that can be dropped in a preferred folder on the disk or copied to a USB flash drive, in order to run it on any machine without setup. It doesn't add new entries to your system registry or need DLLs or other components to work properly. However, it auto-creates an updates an .ini file to remember your settings on exit.

Evaluation and conclusion

It worked smoothly in our testing, without freezing, crashing or showing error messages. We haven't come across any OS compatibility issues on newer Windows, although it hasn't been updated for a while. CPU and RAM usage was minimal. Thanks to its approachable UI and options, Mime Tool can be easily used.
