What is Base64 Encoding?
Base64 is a binary-to-text encoding scheme that represents binary data in an ASCII string format. Each Base64 character represents exactly 6 bits of data. It is widely used to transfer data over media that are designed to handle textual data, such as embedding inline images in HTML/CSS, or transmitting keys in HTTP headers.
Unicode & UTF-8 Compatibility
Native browser methods like `btoa()` and `atob()` fail when handling non-ASCII Unicode characters (such as emojis or non-English characters), throwing a "character out of range" error. The Fawru Base64 tool implements robust UTF-8 byte conversion, ensuring emojis (like 🚀) and international text are encoded and decoded perfectly.
