Hi Product Hunt community! 👋 I’m the maker of chuyenfilenhanh.com—a blazing-fast, privacy-first file processing toolkit designed to run 100% locally in your browser. 💡 The Problem We Are Solving: Most online file converters and editing tools require you to upload your sensitive documents (financial sheets, contracts, personal photos) to a remote cloud server. For many users and companies, this is a major security risk (data leaks, unauthorized storage, privacy breaches). ✨ What chuyenFilenhanh.com Offers (All 100% Client-Side): Zero Server Uploads: Files never leave your device. Everything runs locally in your browser RAM using native JavaScript & WebAssembly. AI-Ready Conversion: Seamlessly convert Word/Excel/PPT into clean Markdown text to easily feed context into LLMs like ChatGPT, Claude, or Gemini. Core Productivity Tools: Batch image cropping, PDF compression, watermarking, and secure offline editing—completely free and without registration. Proud Milestone: We are thrilled to share that this privacy-first approach recently earned us a Top 500 recognition at AI Riser Vietnam 2026 (supported by Google for Developers). I would love to hear your feedback, feature requests, or ideas on how we can make client-side tools even better for everyone. Let me know what you think! 👇
