Hey Product Hunt! 👋 I'm Fatih, the maker of webkitzero.com As a developer, I regularly need to compress videos, convert PDFs, or format images. But every time I searched for a free tool, I was forced to upload my sensitive files to unknown cloud servers, wait for queues, and worry about data privacy. That’s why I built webkitzero. It’s a completely serverless, offline-first web tools ecosystem. By utilizing Next.js Static Export, WebAssembly (like FFmpeg.wasm), and Web Workers, every single tool runs locally in your browser. 🚀 What’s inside? Media: Offline Video Compressor, Video-to-GIF, Image Converter AI & PDF: On-device AI Background Remover, Local PDF RAG Chat Dev & Security: JWT Decoder, OpenAPI Workbench, Security Headers Analyzer The best part? Since there are no server costs for processing, it's incredibly fast and free. Your files never leave your device. I’d love to hear your feedback, bug reports, or feature requests. What tool should I add next? Cheers! 🚀
