Base64 Decode is a free online tool that converts Base64-encoded strings back into readable plain text. Base64 is a binary-to-text encoding scheme commonly used in email attachments, data URIs, API responses, and web tokens like JWTs. When you receive Base64-encoded data and need to read or process the original content, this tool makes the conversion instant.
All decoding happens entirely in your browser using JavaScript — no data is ever sent to a server. The tool fully supports UTF-8 encoded content, so it correctly decodes text in any language including emojis and special characters that were originally Base64-encoded.
