What is Base64 Encoding?
Base64 is a group of binary-to-text encoding schemes that represent binary data in an ASCII string format by translating it into a radix-64 representation. It's commonly used when there is a need to encode binary data that needs to be stored and transferred over media that are designed to deal with text.
This encoding helps to ensure that the data remains intact without modification during transport. Base64 is commonly used in HTML/CSS to embed images inline, in email via MIME, and to encode small data structures in URLs.
Local Processing for Maximum Security
Because developers often encode sensitive tokens, hashes, or passwords using Base64, security is critical. Many online tools send your strings to a server to perform the encoding. This tool performs all encoding and decoding locally within your browser using native Web APIs. Your data is never transmitted.
Features
- Universal encoding: Supports full UTF-8 encoding (which prevents issues with special characters or emojis).
- Real-time translation: Text converts instantly as you type.
- Bi-directional: Easily swap input and output panes to switch from encoding to decoding.
