QuickConvertKit - Convert files in your browser. Your data never leaves.

Hey Product Hunt community! 👋 I’m Syed Hassan Fida, co-founder of QuickConvertKit, and I’m thrilled to share what we’ve built. As developers, we were frustrated with online file converters that made us upload sensitive documents, JSON configs, or client work to external servers. So we built something different: a 50+ tool conversion suite that runs entirely in your browser using WebAssembly. Why this matters: • Your files never leave your computer • Conversions happen instantly (no upload/download delays) • 100% free — no watermarks, signups, or limits We built this for developers, designers, students, and professionals who value privacy, speed, and simplicity. Try our most popular tools right now: → MP3 to WAV (lossless, local processing) → JSON Validator & Formatter → HTML to PDF (preserves formatting) → PDF Compressor & Merger We’d love your feedback! What tools would you add? Any workflows we should improve? Check it out and convert with confidence. 🚀 Link: https://quickconvertkit.com
