Hey Product Hunt 👋 I built Tools OP because I was tired of utility sites that make you create accounts, watermark your files, or silently upload everything to their servers. Every tool on Tools OP runs client-side in your browser. Your PDFs, images, and text never leave your device. What's included: 🗂 PDF Tools — Merge, split, compress, watermark, convert images to PDF, extract pages as PNG/JPG 🖼 Image Tools — Resize, crop, compress, convert between JPG/PNG/WebP/GIF 💻 Developer Tools — JSON formatter, Base64 encoder/decoder, UUID generator, SHA-256/MD5 hash, regex tester, URL encoder, Unix timestamp 📝 Text Tools — Word counter, case converter, lorem ipsum generator 💰 Finance Tools — EMI calculator, SIP calculator, GST calculator, compound interest 📈 SEO Tools — Meta tag previewer, UTM builder, robots.txt generator 🔒 Security Tools — Password generator, hash generator 🤖 AI Tools (the fun part) — Four Transformers.js-powered tools that run a local AI model right in your tab: AI Text Summarizer — condense long articles instantly Sentiment Analyzer — detect positive/negative tone Language Detector — identify 20+ languages Image Classifier — recognize 1,000 object categories Plus a Browser AI Chat powered by WebLLM (Llama 3.2 + Phi-3.5, running via WebGPU). Chat with an LLM with zero data leaving your device. What makes it different: Zero cookies, zero fingerprinting — analytics use anonymous session IDs that clear on tab close Self-hosted analytics — I built a GA-like dashboard (sessions, scroll depth, bounce rate, JS error tracking) without third-party scripts 100+ blog posts covering every tool with guides, comparisons, and SEO tips Completely free — no freemium gates, no file size paywalls
