Building a Privacy-First PDF Toolkit That Runs Entirely in Your Browser

The Problem Ever needed to merge a few PDFs or compress a large file, only to find yourself uploading sensitive documents to some random website? I've been there too many times. Most online PDF tools: Upload your files to their servers Have unclear privacy policies Are bloated with ads and upsells Require registration for basic features I wanted something better: a tool that's fast, free, and respects your privacy. The Solution I built PDF Tools Online - a completely client-side PDF processor. Your files never leave your device. Core Features 📄 PDF Merge - Combine multiple PDFs into one document ✂️ PDF Split - Extract specific pages or split into separate files 📉 PDF Compress - Reduce file size without significant quality loss 🖼️ PDF to Image - Convert PDF pages to PNG/JPG 📷 Image to PDF - Create PDFs from multiple images Tech Stack The app is built with: React - For the UI pdf-lib - Client-side PDF manipulation Tailwind CSS - Styling Vite - Build tool Why Client-Side Processing?
