How Base64 Encoding Works
Base64 is a binary-to-text encoding scheme that translates binary data into a set of 64 ASCII characters (A–Z, a–z, 0–9, +, /) with = padding. It is universally used in email protocols (MIME), Basic Auth headers, and inline image Data URIs.
Frequently Asked Questions
Does Base64 encrypt my data?

Does this encoder support UTF-8 special characters and emojis?
Yes! ToolMint properly handles multi-byte UTF-8 characters and emojis without mangling accents or symbols.
