Base64 Encode

Tool guide
Convert UTF-8 text and Base64
Encode text as Base64 or decode Base64 into UTF-8 text. The encoding is reversible and provides no encryption.
How to use
  1. Enter text or a Base64 string.
  2. Choose Encode or Decode.
  3. Use the file/Base64 tool for images or binary files.
Example and expected result
Text: hello
Base64: aGVsbG8=
Decoded: hello
Capabilities and limits
  • This page handles text; arbitrary binary data may not display as readable text.
  • Base64URL uses a different alphabet with - and _.
Troubleshooting
Check padding, the alphabet and any Data URL prefix. For garbled output, confirm the original character encoding.
Data processing and storage
Text is converted in the current page without automatic saving. Sensitive Base64 content remains recoverable.
