Use cases

  • Encode text as URL-safe Base64
  • Decode Base64-encoded data
  • Percent-encode or decode URL components
  • Work with JSON payloads and API tokens
  • Escape or decode reserved HTML characters

Keep in mind

  • Base64 is encoding, not encryption. It does not hide or protect the underlying data.
  • URL encoding does not encrypt data — it only makes characters safe for URLs.
