About Base64

• Base64 is a binary-to-text encoding scheme that represents binary data in ASCII format
• Commonly used for encoding data for transmission over text-only channels
• Used in email, APIs, and web applications for data representation
• Increases data size by ~33% but makes it safe for text-based transport
• This tool works 100% client-side - no data is sent to servers
