Base64 Encoder and Decoder
A simple, fast, and secure tool to encode text into Base64 strings or decode Base64 strings back into readable text. Base64 encoding is 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 textual data.
How to use
- Encode: Paste your text into the left box and click Encode to see the Base64 result.
- Decode: Paste your Base64 string into the right box and click Decode to see the original text.
What is Base64?
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. The term Base64 originates from a specific MIME content transfer encoding.
Common Uses
- Email Attachments: Sending binary files (images, documents) via email.
- Data URIs: Embedding small images directly into HTML or CSS files to reduce HTTP requests.
- Basic Obfuscation: Hiding data from casual view (though it is NOT encryption).
