FuaHub
230+ free online tools. Zero uploads, zero tracking.
FuaHub is a privacy-first web toolkit featuring 230+ online tools for PDF, images, text, and code. Unlike traditional tools that upload files to servers, FuaHub processes everything 100% locally in your browser using WebAssembly and Canvas API. Your files never leave your device. Features include PDF merge/split, image compression, HEIC to JPG, JSON formatter, and UUID generator. Fast, free, and works offline.
Hey Product Hunt community! 👋
I built FuaHub out of personal frustration: every time I needed to merge a PDF, convert an iPhone HEIC photo, or format a JSON payload, traditional online tools required uploading my files to unknown remote servers. For sensitive contracts, tax records, or personal photos, that always felt like an unnecessary privacy risk.
So I built FuaHub — a 100% client-side web toolkit with 230+ online tools.
⚡ Key Features:
• 🔒 100% Private: Everything runs locally inside your browser using WebAssembly & Canvas API. Your files NEVER leave your device.
• 🌐 Offline-Ready: Once the page is loaded, client-side tools work even without an internet connection.
• 🚀 Zero Friction: No login, no accounts, no watermarks, and no limits.
From PDF merging and HEIC conversion to regex testing and password generation, FuaHub aims to be your privacy-first digital Swiss Army knife.
I’d love to hear your thoughts! Which tool category do you find most useful in your daily workflow, and what tools should I build next?
Thanks for checking out FuaHub! 🙌
