Multi-Format Encoder

Encode text into Base64, hex, binary, URL, HTML entities, ROT13 and more, all at once.

A multi-format encoder shows the same text in every common encoding at once — Base64, Base64url, hexadecimal, binary, decimal bytes, URL percent-encoding, HTML entities, Unicode escapes, ROT13 and a data URI — so you can copy whichever you need without switching tools.

Frequently asked questions

Why does decoding suggest several formats?

Because the formats overlap. A short Base64 string is frequently also valid hexadecimal, and both will decode without error. The tool shows every interpretation that succeeded and leaves you to judge which result is actually meaningful.

How to use the multi-format encoder

  1. 1Enter or paste your text.
  2. 2Choose the direction.
  3. 3The result appears immediately — copy or download it.
