It's a collection of 99+ free online tools designed specifically for developers.</p> <p><strong>The Problem I Solved:</strong></p> <p>As a developer, I found myself constantly jumping between 10+ different websites to handle simple tasks:</p> <ul> <li>Format JSON or beautify JavaScript</li> <li>Convert images to PDF or vice versa</li> <li>Test regex patterns</li> <li>Check DNS records</li> <li>Generate QR codes</li> <li>And so many more...</li> </ul> <p>I wanted ONE place where I could access all these tools without installation, registration, or bloatware.</p> <p><strong>What I Built:</strong></p> <p>OnlineView is a unified platform with tools across multiple categories:</p> <p>📄 <strong>PDF Tools:</strong></p> <ul> <li>Edit PDFs (add text, annotations)</li> <li>Merge multiple PDFs</li> <li>Compress PDFs</li> <li>Add watermarks</li> <li>Convert PDF to images</li> </ul> <p>🖼️ <strong>Image Tools:</strong></p> <ul> <li>Image converter (PNG, JPG, WebP, BMP)</li> <li>Convert images to PDF</li> <li>HEIC to JPG converter (for iPhone photos)</li> <li>QR code generator</li> <li>SVG to PNG converter</li> </ul> <p>💻 <strong>Developer Tools:</strong></p> <ul> <li>JSON formatter &amp; validator</li> <li>JavaScript beautifier</li> <li>SQL formatter</li> <li>RegEx tester (with live matching)</li> <li>PHP sandbox</li> <li>CSS &amp; YAML formatters</li> <li>Markdown to HTML converter</li> <li>Color picker (Hex, RGB, HSL)</li> </ul> <p>🌐 <strong>Network Tools:</strong></p> <ul> <li>Check your IP address (IPv4/IPv6)</li> <li>DNS lookup</li> <li>Website uptime checker</li> </ul> <p>🛠️ <strong>Utilities:</strong></p> <ul> <li>Password generator</li> <li>Word counter (words, characters, reading time)</li> <li>Unit converter</li> <li>Hash generator (MD5, SHA-256, etc.)</li> <li>Lorem Ipsum generator</li> </ul> <p><strong>Why This Approach:</strong></p> <p>✅ <strong>100% Browser-Based</strong> - All processing happens locally on your device<br> ✅ <strong>Privacy-First</strong> - Your data never leaves your browser or goes to any server<br> ✅ <strong>Zero Installation</strong> - No downloads, no dependencies, no bloatware<br> ✅ <strong>Completely Free</strong> - No premium plans, no hidden fees<br> ✅ <strong>Fast &amp; Lightweight</strong> - Built with vanilla JavaScript (no heavy frameworks)<br> ✅ <strong>Mobile Friendly</strong> - Works perfectly on smartphones and tablets</p> <p><strong>Tech Stack:</strong></p> <ul> <li>Vanilla JavaScript (no React, Vue, or frameworks)</li> <li>HTML5 &amp; CSS3</li> <li>Browser APIs (pdf-lib, pdf.js, and native Web APIs)</li> <li>Optimized for performance</li> </ul> <p><strong>Current Status:</strong></p> <p>The site is live at onlineview.net and launching on Product Hunt tomorrow!
