Everything runs locally in your browser - your files never leave your device.</p> <h2> Why I Built This </h2> <p>I was tired of online tools that upload your files to unknown servers, require signup for basic operations, slap watermarks on everything, or limit you to a few free uses per day.</p> <p>So I built something different: a toolkit where ALL processing happens on YOUR device.</p> <h2> Tech Stack </h2> <ul> <li> <strong>C++ core</strong> compiled to <strong>WebAssembly</strong> (with SIMD)</li> <li> <strong>ONNX Runtime Web</strong> for AI model inference</li> <li> <strong>Cloudflare Pages</strong> for hosting</li> <li> <strong>28 languages</strong> with full i18n support</li> </ul> <h2> Features </h2> <h3> Image Tools </h3> <ul> <li>Compress, resize, crop, convert (JPG/PNG/WebP/AVIF/HEIC)</li> <li>GIF maker, collage creator, meme generator</li> <li>QR code generator and reader</li> </ul> <h3> AI-Powered Tools </h3> <ul> <li>Remove Background - works great on portraits and products</li> <li>Colorize Photos - brings black and white photos to life</li> <li>Enhance Photo - fixes dark, noisy, or dull images</li> <li>Cartoonize - turn photos into cartoon style</li> <li>OCR - extract text from images</li> </ul> <h3> PDF Tools </h3> <ul> <li>Merge, split, compress PDFs</li> <li>Convert images to/from PDF</li> </ul> <h3> Computer Vision Lab </h3> <ul> <li>Edge detection, contour analysis</li> <li>Histogram analysis, watershed segmentation</li> <li>Hough transform, feature detection</li> </ul> <h2> The Privacy Angle </h2> <p>Every single operation - including AI inference - runs in your browser. The AI models are downloaded once, cached locally, and executed via WebAssembly. No server ever sees your files.</p> <h2> Try It Out </h2> <p>Check it out at <a href="https://pixlane.media" rel="noopener noreferrer">pixlane.media</a> - completely free, no signup required.</p> <p>I would love to hear your feedback and suggestions for new tools!</p> webdev javascript webassembly opensource
