Base64 is a method of encoding binary data into ASCII text. It's commonly used for transmitting data in email, storing complex data in XML or JSON, and encoding images in CSS or HTML.
Encode binary files for email transmission and data storage.
Embed images directly in HTML, CSS, or JSON as base64 strings.
Transmit binary data through JSON APIs and web services.
Basic text obfuscation and character encoding for special characters.
Base64 is a binary-to-text encoding scheme that represents binary data in an ASCII string format. It uses 64 characters (A-Z, a-z, 0-9, +, /) to encode data.
Base64 ensures data integrity during transport over systems designed for text data. It's widely used in email, web development, and APIs to handle binary data safely.
No, Base64 is not encryption or security. It's just encoding - anyone can decode Base64 data. Use proper encryption for sensitive information.
Yes, Base64 encoding increases data size by approximately 33% due to the encoding overhead. Every 3 bytes become 4 characters.
Standard Base64 can include line breaks for readability, but our tool handles both formats. For web use, line breaks are typically removed.
