Hello, Tool Vault!SGVsbG8sIFRvb2wgVmF1bHQhUnderstanding Base64 Encoding
Base64 is a binary-to-text encoding scheme that represents binary data in an ASCII string format by translating it into a radix-64 representation. It is widely used in MIME email formatting, embedding images in CSS/HTML (Data URLs), and transmitting complex data over network protocols that only support text.
Security & Privacy Assurance
Encoding and decoding are handled strictly on your device using native browser crypto and text encoder utilities. Zero network transmissions.
