About This Tool
Our Base64 Encoder and Decoder makes it easy to convert plain text into Base64 format or decode Base64 strings back into readable text — all in a single click. Base64 encoding is commonly used for embedding images in HTML/CSS, sending binary-safe data through APIs, storing data in JSON or XML, and working with authentication tokens.
Simply switch between the Encode and Decode tabs depending on what you need. When encoding, paste in your plain text and get a Base64 string ready to use anywhere. When decoding, paste in a Base64 string and instantly see the original text — useful for inspecting API tokens, debugging encoded payloads, or reading data your app or browser has stored in Base64.
The tool fully supports Unicode, so text with emojis, accented characters, or non-Latin scripts (like Arabic, Chinese, or Cyrillic) encodes and decodes correctly — something many basic Base64 tools get wrong.
Everything runs client-side in your browser. Nothing you type is ever sent to a server, so it’s safe to use with sensitive tokens or private data. No login, no watermark, no daily limit.
