What is Base64?
- Base64 is an encoding scheme that converts binary data into ASCII text using 64 printable characters.
- It is commonly used to embed images, transmit data in URLs, and encode email attachments.
- Base64 is NOT encryption. It is reversible and provides no security on its own.
- Each Base64 character represents 6 bits of data; every 3 bytes of input become 4 Base64 characters.
- The alphabet used is A-Z, a-z, 0-9, +, / with = used for padding.
For actual data security, try our Hash Generator (SHA-256).
