All in one Base 64 Converter tool

We are offering Base64 Encoder and Decoder to convert your data. It is an effective tool for debugging and testing the decoding process. It will also help you to understand how the Base 4 decoding works. No need to register, copy and paste your data or upload data to encode or decode.

What is Base64?

Base64 is a binary-to-text encoding scheme that converts binary data into a textual format, allowing it to be transmitted as text over text-oriented channels, such as email or HTML. It works by representing binary data using a set of 64 printable characters (hence the name Base64) composed of letters, numbers, and symbols.

Base64 encoding and decoding are methods used to convert data into a format that can be safely transmitted over various systems that may not properly handle binary data. The encoder converts binary data into a text format, consisting of a set of 64 characters, hence the name Base64. This format is used to encode binary data, such as images or files, into a textual representation, making it more suitable for transmission over networks.

Conversely, the decoder performs the reverse operation, converting the Base64-encoded text back into its original binary form. This allows the data to be interpreted and used as intended by the receiving system.
