All Tools Together is a free online toolkit with 284 tools across 19 categories. We focus on practical calculators and utilities that run entirely in your browser — no accounts, no uploads, and no tracking of your inputs.
Our mission
Useful tools should be fast, free, and respectful of privacy. Most of our calculators, converters, PDF tools, and image tools process everything on your device. You can use them instantly without signing up or sending sensitive data to a server.
How we build and verify tools
Every calculator uses standard, publicly documented formulas (loan amortization, BMI / Mifflin-St Jeor, unit conversions based on international definitions, etc.). We check results against known examples and reference implementations. Financial and health tools include clear explanations, step-by-step how-tos, and FAQs. Content is reviewed for accuracy and updated when formulas or best practices change. Last major content review: October 2026.
