Encode / Decode

Base64, URL, and HTML entity encoding and decoding utilities.

**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. ### Use cases - Developers inspecting or preparing data for APIs - Troubleshooting URL encoding issues in web applications - Quickly escaping HTML for rendering or debugging - Decoding Base64 payloads or configuration values - Anyone who needs fast, private text encoding/decoding in their browser
