Text Encoding Converter
Type or paste any text to instantly see it represented as UTF-8 hex bytes, binary, Unicode code points, Base64, URL-encoded and HTML-entity-escaped — all computed locally in your browser, side by side.
How it works
Whatever you type in the input box is instantly converted into six common encodings shown below it: UTF-8 hex bytes, binary, Unicode code points, Base64, URL encoding and HTML entities. Click "Copy" next to any result to copy it to your clipboard.
Tip
Unicode code points are shown per character (using proper code point iteration), so emoji and other characters outside the Basic Multilingual Plane are represented correctly, unlike naive string indexing.
Is this reversible?
This tool only converts text into these formats, it does not decode them back into text. To go the other direction, use a dedicated decoder for that specific format.
