Annoying.</p> <p>## What I built</p> <p>A collection of simple tools that run entirely in your browser:</p> <ul> <li>🖼 <strong>Image Compressor</strong> – compress JPG/PNG client-side</li> <li>📄 <strong>PDF Compressor</strong> – same for PDFs</li> <li>🔄 <strong>WebP Converter</strong> – convert images to WebP instantly</li> <li>📝 <strong>Lorem Ipsum</strong> – customizable placeholder text</li> <li>🔤 <strong>Text Case Converter</strong> – camelCase, snake_case, kebab-case, and 7 more</li> <li>🔍 <strong>Text &amp; JSON Diff</strong> – paste two texts, see the diff highlighted </li> <li>📱 <strong>QR Code Generator</strong> – generate and download QR codes</li> </ul> <p>## The key difference</p> <p>Nothing gets uploaded to a server. Everything processes locally in your browser.<br> No account. No tracking. Always free.</p> <p>👉 <a href="https://onlinetoolprovider.com" rel="noopener noreferrer">https://onlinetoolprovider.com</a></p> <p>Would love feedback on what tools you'd want to see added next!</p> webdev productivity tooling opensource
