👋 Hi Product Hunt! I'm excited to share **Base64 Buddy** — a Chrome extension I built to make Base64 encoding and decoding faster, simpler, and more private. As a developer, I found myself constantly switching between online Base64 tools whenever I needed to inspect API payloads, generate Data URIs, or decode files. Most tools were cluttered with ads, required uploading data to external servers, or lacked useful features like previews and file metadata. So I built Base64 Buddy. ✨ Key features: • Encode and decode files directly in your browser • Real-time image and file previews • Data URI support • Smart file type detection • Detailed file metadata and history • Dark mode • 100% offline and privacy-first No sign-ups, no uploads, and no tracking. Everything happens locally on your device. I'd love to hear your feedback: 👉 What Base64-related features would make your workflow easier? 👉 Are there other developer utilities you'd like to see integrated in the future? Thanks for checking it out and supporting indie builders! 🚀
