Tools OP
One Place for All Your Tools — all in your browser.
All-in-one platform with 37+ free online tools: PDF merge, image resize, JSON formatter, EMI calculator, Base64 encoder, word counter, and more. Browser-based, no sign-up.
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
