Base64 Right-Click Decoder

Decode base64 / URL / HTML / hex on any page and open, preview, or copy the result. No external decoder site needed.

Select any base64 string on any webpage, right-click, and decode it instantly right where you are — no need to visit an external decoder site. Features: • Right-click → "Base64 디코드 → 링크 열기": decodes the selected text; if the result is a URL, it opens in a new tab immediately. • Right-click → "Base64 디코드 → 결과 복사": shows the decoded result in a small on-page overlay with a one-click copy button. • Works on arbitrary base64 text, not just links — tokens, hashes, payloads, anything. • Handles line breaks / whitespace, URL-safe characters (- _), and missing padding automatically. • Everything runs 100% locally in your browser. Privacy: • This extension collects NO data. • No analytics, no network requests, no remote code. • All decoding happens locally on your device. • Minimal permissions: contextMenus, activeTab, scripting. Every action is triggered only by your explicit right-click.
