Base64 Encoder / Decoder


This page, explained below.

Base64 is a binary-to-text encoding scheme that is commonly used to encode data, especially when that data needs to be stored and transferred over media designed to deal with text. This encoding helps to ensure that the data remains intact without modification during transport. Base64 is used commonly in a number of applications including email via MIME, as well as storing complex data in XML or JSON.

The Base64 encoding scheme uses a specific set of 64 different ASCII characters (A-Z, a-z, 0-9, + and /) to represent the data. Also, an equal sign (=) is used as a special character for padding in certain situations. Base64-encoded data takes about 33% more space than the original data.

Our Base64 converter tool is here to simplify and automate the process of encoding and decoding Base64 strings. This is useful in a myriad of instances. Developers may need to encode images in Base64 to inline them in CSS files, saving HTTP requests. Or, you might need to decode a Base64 string you received, in order to inspect the data. In privacy-focused applications, Base64 can be used to encode a piece of data, obscuring it from casual view.

To use this tool, simply type or paste your data into the Input Text field and click the relevant button. If you're encoding, you'll input plaintext and receive a Base64 string. If you're decoding, you'll input a Base64 string and receive plaintext. The tool processes the conversion client-side - your data isn't shared over the internet, so you can be confident your data remains secure.

Quick and efficient, this tool is an invaluable aid for anyone who regularly deals with Base64 encoding and decoding, whether you're a web developer, a data analyst, or a cybersecurity professional.
