What is Base64?
Base64 turns binary data into plain ASCII text so it can travel safely through email, JSON, HTML and URLs. It is used for data URLs, API tokens, basic auth headers and embedding small images in CSS.
Base64 Encoder / Decoder
Encode or decode text (UTF-8 safe — emoji and all languages work), or convert a file into a Base64 data URL for embedding.
