Base64 Encoder / Decoder

Encode plain text to Base64 or decode Base64 strings back to text in the browser.

When to use it

  • Decode a small API payload while debugging a request or log line.
  • Encode sample text for documentation, test fixtures, or quick command examples.
  • Check whether a copied token-like value is encoded text before investigating further.

Examples

  • Decode SGVsbG8gd29ybGQ= to confirm a fixture value.
  • Encode a small JSON example before pasting it into a config field that expects Base64.
  • Decode a data URI fragment to inspect what is actually embedded.

Limitations

Base64 is encoding, not encryption. Anyone can decode it. Do not treat Base64 output as a secure way to hide secrets.
