Hey everyone!
As developers and internet users, we handle sensitive documents daily—tax forms, contracts, and personal IDs. Most online PDF editors require you to upload these files to their servers. This always felt like a massive privacy risk to me.
That’s why I built SmartToolsHub (https://smarttoolshub.tech/).
How it works under the hood 🛠️
To solve the privacy issue, I engineered the core features (Merge, Split, Compress) to process everything 100% locally inside the client's browser window.
By leveraging native WebAssembly (WASM), the application does the heavy lifting right on your device. Your confidential documents never touch a remote server, meaning complete data security.
Features:
- 100% Free: No paywalls, no feature restrictions.
- Zero Server Uploads: Complete client-side privacy.
- Fast & Lightweight: Powered by WASM and Tailwind CSS.
We just launched on Product Hunt today! I would love for the community to test it out, give me some technical feedback, and support our launch here:

Let me know what features I should add next!
