Hey Product Hunt! 👋 I built ZetTool because I kept bouncing between five different websites just to do simple everyday things — checking my BMI, converting a case (UPPERCASE/lowercase/Title Case), counting words for an assignment, or converting a number into words for a cheque. ZetTool brings all of these into one free, no-sign-up site — 20+ tools including calculators (Age, EMI, BMI, Fuel Cost), a Unit Converter, PDF tools (Merge, JPG to PDF, Word to PDF), and text tools like the Case Converter and Word Counter. A couple of things I focused on: No sign-up, no ads clutter — open a tool, get your answer, done Privacy-first — most tools (including Case Converter, Word Counter, PDF tools) run entirely in your browser using JavaScript, so nothing you type or upload ever touches a server Free forever — no premium tier, no paywall Would love your feedback — especially if there's a tool you wish existed that isn't here yet. I read every comment! 🙏
