How to encode or decode Base64

Convert Unicode text to Base64 or decode a Base64 value back to readable text without sending the content to an API.

  1. 1Choose Encode or Decode for the direction you need.
  2. 2Paste the source text or Base64 value into the input editor.
  3. 3Run the conversion, review the result, and copy it when ready.

Encoding behavior

  • Handles UTF-8 text including accented characters and emoji.
  • Rejects malformed Base64 instead of silently returning corrupted text.
  • Base64 is an encoding, not encryption, and does not protect secrets.
