What is Base64 Encoding?
Base64 is a binary-to-text encoding scheme that represents binary data in ASCII string format. It's commonly used for encoding data in emails, data URLs, and transferring binary data over text-based protocols.
Common Use Cases:
- Email attachments (MIME)
- Data URLs in HTML/CSS
- API token encoding
- Embedding images in JSON
- Basic data obfuscation
- Storing binary in text fields
Note: Base64 encoding increases data size by approximately 33%. It's not encryption and should not be used for security purposes.
