Whether you're browsing developer forums, GitHub issues, Reddit, or tech communities where Base64 is commonly used, this extension automatically detects Base64 strings on the fly, replaces them in-place with readable text, and lets you manage your own frequent Base64 snippets in seconds. ✨ What's New in v1.1.0: • 🔖 Quick Base64 Snippets Manager: Save frequent contacts (email, URL, etc.) with custom tags directly in the popup for instant Base64 copying. • 💡 Smart Auto-Detect & Instant Decoder: Paste or type any Base64 string into the popup to see a real-time decoded preview with one-click "Copy Text" and "Use Plain" actions. 🌟 Key Features: • ⚡ Auto-Scan & In-Place Replacement: Automatically identifies Base64 strings as you browse (including dynamic SPA content) and replaces them with decoded text. • 💡 Smart Auto-Detect & Instant Decoder: Need to decode Base64 from WeChat, Slack, terminal, emails, or PDFs? Simply paste it into the popup input box for instant auto-detection and one-click plaintext copying. • 🔖 Quick Base64 Snippets Manager: Frequently sharing your email or URL as Base64 to prevent spam? Save them once with custom tags; the extension automatically encodes them and syncs across all your devices via chrome.storage.sync. • 📋 One-Click Copy: A discreet copy icon appears right next to decoded text and saved snippets. One click copies it to your clipboard with instant visual feedback. • 🔍 View Original Base64 on Hover: Hover over any in-page decoded text to inspect the original Base64 string in a tooltip. • 🛡️ Smart Anti-False-Positive Filter: - Full UTF-8 support for non-Latin scripts (Chinese, Japanese, Korean), emojis, and special characters. - Intelligent heuristics filter out ordinary English words, Git commit hashes, UUIDs, and pure numbers to keep webpages clean. • 🎛️ Minimalist ON/OFF Toggle: Click the extension icon to toggle the decoder with a clean switch. Turning it off instantly restores the original text without refreshing the page. • 🔒 100% Privacy & Security: All processing occurs entirely locally inside your browser.
