What is the Base64 / URL / HTML Encoder-Decoder?
This tool encodes and decodes text using three common web schemes: Base64, URL percent-encoding and HTML entity encoding.
How to use it
- 1Pick a scheme.
- 2Choose encode or decode.
- 3Enter text and read the result.
How it works
Base64 uses a UTF-8 safe encode/decode path so emoji and accents survive. URL mode uses encodeURIComponent/decodeURIComponent. HTML mode escapes and unescapes the five core entities.
Limitations & notes
- Base64 is encoding, not encryption — it provides no confidentiality.
