Free online utilities for the small jobs that do not fit anywhere else: generating a strong password, finding out your IP address, counting how old you are in seconds, converting cups to grams at midnight when you cannot remember. Every tool is ad-light, signup-free, and runs in your browser.
What you can do here
Security and secure sharing
The Password Generator creates cryptographically secure passwords with configurable length, character classes, and a readability mode (pronounceable passwords that are still strong). Runs locally using the Web Crypto API, so the generated password never leaves your device. The QR Code Generator makes a QR from any URL, text, contact card, or Wi-Fi credentials and downloads as PNG or SVG.
IP and networking
The What Is My IP tool shows your public IPv4 and IPv6, ISP, and approximate location. Supporting guides explain IPv4 addresses, IPv6 addresses, public vs private IPs, static vs dynamic IPs, how to hide your IP, how to change your IP, how to find your ISP, and geolocation accuracy.
Time and dates
The Age Calculator gives your age in years, months, days, plus total hours, minutes, and seconds, and the day of the week you were born. The Date Calculator computes difference between any two dates. The Hours Calculator works as a time card with start, end, breaks, and hourly rate. The Time Zone Converter handles all IANA timezones with live current-time.
Conversions and home
The Cooking Measurement Converter handles cups, tablespoons, grams, ounces, adjusting weights for ingredient density. The Speed Distance Time Calculator solves any of the three given the other two. The Electricity Cost Calculator estimates daily, monthly, and annual cost of running any appliance. The Scientific Calculator offers full scientific functions in a browser-based calculator that works on keyboard and touch.
Privacy, in plain English
The Password Generator, QR Code Generator, and most other tools here work without sending your input to any server. The Password Generator uses the Web Crypto API locally. The QR Code Generator renders the code client-side in JavaScript. The What Is My IP tool is the one exception — it reads your IP from our server because your browser cannot see its own public IP, but we do not log it.
Frequently asked questions
Is the Password Generator really secure?
Yes. It uses the browser’s crypto.getRandomValues(), which is the cryptographically secure random source used by TLS. The generated password is never transmitted.
Why does the IP tool show a different city than I am in?
IP geolocation is approximate, typically accurate to city but sometimes only to region level. It gets worse on a VPN, corporate network, or mobile data. The geolocation accuracy guide covers why.
