About Base64
Base64 is an encoding that represents binary data as ASCII text. It is commonly used to embed data in text-based formats like JSON, HTML, or URLs.
Base64 is often used for:
- Encoding small binary payloads for transport or storage
- Basic HTTP authentication strings
- Embedding images as data URLs
Note: Base64 is not encryption. Anyone can decode it back to the original data.
