Decode Base64 into Text Online Tool

Decodes Base64 encoded text into plain text. The binary data encoded into Base64 is decoded into text characters. Converting text to Base64 can be useful to visually obscure text while still allowing for easy decoding. Base64 is easily reversed and this obscuring is not cryptographically secure.

How to Use

1. Enter Base64 encoded text into the input box.

2. Press the "Decode" button and Base64 encoded text characters will be decoded into text characters.

3. Pressing the "Decode" button will convert Base64 encoded text in the output box back to the input box

About Base64

Base64 is a is a widely used method for converting binary data into a text format. Base64 converts binary bits into a set of 64 characters consisting of the 26 uppercase letters, the 26 lowercase letters, the 10 numeric digits and the characters + and /. An additional character = is used to indicate the presence of padding bits.

Character Encoding

The selection of character encoding affects how the input text characters are converted into binary data. As Base64 encodes binary data, selecting different text encoding for the input characters results in different Base64 output.

UTF-8 / ASCII	UTF-8 is the 8-bit Unicode encoding. It is designed to be backwards compatible with ASCII encoding and encoded text will be identical to ASCII if only ASCII characters are used as input.
UTF-16	UTF-16 is the 16-bit Unicode encoding. It is the standard encoding used for Strings in Java and Javascript.
UTF-32	UTF-32 is the 32-bit Unicode encoding. Each character in UTF-32 has the same value as its codepoint.
