A growing collection of free tools for everyday tasks. Flip a coin, generate a secure password, test your typing speed, convert between Roman and Arabic numerals, check live currency exchange rates, and more.
All tools run entirely in your browser — no accounts, no downloads, no data sent to any server. Just open and use.
Alongside our unit converter collection, ConvertToolPro hosts a set of standalone utility tools that don't fit neatly into a conversion category — but come up constantly in everyday life.
Need a random coin toss for a decision? A strong password for a new account? A quick WPM check before a job application? These tools are designed to be fast, distraction-free, and entirely private — nothing is tracked or stored beyond your browser session.
We'll continue adding new tools over time. All are free, with no sign-up and no usage limits.
Flip a virtual coin for heads or tails. Includes a 3D animation, spacebar shortcut, flip history, and running stats. Uses Math.random() — each flip is independent with equal probability.
Generate up to 20 random integers within any range you specify. Supports unique-only mode and keeps a history of previous results. Useful for draws, games, and sampling.
Create secure passwords up to 64 characters long. Choose uppercase, lowercase, numbers, and symbols. Passwords are generated using crypto.getRandomValues() — cryptographically strong and never transmitted anywhere.
Convert any integer from 1 to 3,999 to Roman numerals, or translate a Roman numeral back to its Arabic equivalent. Includes a reference grid for 1–100 and a one-click swap between modes.
Convert between 31 major currencies using live exchange rates fetched from the Open Exchange Rates API. Rates refresh automatically and the tool gracefully falls back to cached data if the API is unavailable.
Measure your typing speed in WPM (words per minute) and accuracy percentage. Choose from three difficulty levels — easy, medium, or hard — with multiple passages in each. Results are shown per-session only and are not stored.
Yes, completely free. No sign up, no account, no limits, no ads inside the tools. Just open and use.
