The Base64 Encoding tool is used to encode strings into Base64 format. It can convert the input string into Base64 format for transmission and use in different systems.

Features:

1. Input the string to be encoded.

2. The tool encodes the string into Base64 format and displays it in the output area.

3. Supports decoding of Base64 encoding. Input the string that has been encoded in Base64 format.

Use cases:

1. Data transmission: During data transmission, binary data needs to be converted into text data for transmission. Base64 encoding can convert binary data into ASCII text for transmission and use between different systems.

2. Encryption and decryption: Base64 encoding can also be used as a simple encryption method. After encoding the original data, the security of the data can be increased. Base64 encoding can be used for conversion when simple encryption of data is required.

3. Encoding conversion: Sometimes different encoding methods are used in different systems, and encoding conversion is required. Base64 encoding can convert data with different encoding methods, making data exchange between different systems easier.
