Encode / Decode

About

**Convert text between encodings instantly — all locally, nothing leaves your browser.**

Encode / Decode is a fast, lightweight Chrome extension that gives you three essential text transformation tools in one clean popup:

- **Base64** — Encode any Unicode text to Base64, or decode Base64 back to readable text. Full Unicode support via UTF-8.
- **URL** — Percent-encode strings for safe use in URLs, or decode percent-encoded sequences back to plain text.
- **HTML Entities** — Escape special HTML characters (`&`, `<`, `>`, `"`, `'`) for safe rendering, or decode named entities (&amp;, &lt;, &gt;), numeric character references, and hex references back to their original characters.

### Features

- **All processing is local.** Your text never leaves your browser — no servers, no telemetry, no network requests.
- **Copy with one click.** Every output has a dedicated copy button with visual confirmation.
- **Keyboard shortcut.** Press `Ctrl+Enter` to encode without reaching for the mouse.
- **Character counts.** See output length at a glance.
- **Clear error messages.** Invalid input is explained in plain language, not cryptic error codes.
- **140+ interface languages.** Switch languages on the fly from the dropdown — includes RTL support for Arabic, Hebrew, Persian, Urdu, and others.
- **Clean, accessible UI.** Built with WAI-ARIA tab semantics, keyboard navigation, and screen-reader labels.
