Most online PDF editors require you to upload these files to their servers. This always felt like a massive privacy risk to me.</p> <p>That’s why I built SmartToolsHub (<a href="https://smarttoolshub.tech/" rel="noopener noreferrer">https://smarttoolshub.tech/</a>).</p> <h3> How it works under the hood 🛠️ </h3> <p>To solve the privacy issue, I engineered the core features (Merge, Split, Compress) to process everything 100% locally inside the client's browser window. </p> <p>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.</p> <h3> Features: </h3> <ul> <li>100% Free: No paywalls, no feature restrictions.</li> <li>Zero Server Uploads: Complete client-side privacy.</li> <li>Fast &amp; Lightweight: Powered by WASM and Tailwind CSS.</li> </ul> <p>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:<br> <a href="https://www.producthunt.com/p/smarttoolshub" rel="noopener noreferrer">https://www.producthunt.com/p/smarttoolshub</a></p> <p>Let me know what features I should add next!</p> productivity pdftodoc privacy opensource
