💡 Base64 Encoding Guide
🔒 What is Base64?
Base64 is an encoding scheme that converts binary data into ASCII
text format using 64 different characters (A-Z, a-z, 0-9, +, /).
💼 Common Use Cases
Embedding images in HTML/CSS, transferring data in APIs, encoding
credentials, storing binary data in text formats like JSON or XML.
📊 Size Increase
Base64 encoding increases data size by approximately 33%. This is
because 3 bytes of binary data become 4 bytes of Base64 text.
🌐 UTF-8 Support
This tool supports UTF-8 encoding, allowing you to encode and
decode text in multiple languages including special characters and
emojis.
