Everyday utilities: the small tools you will use weekly
Every household and office accumulates the same small tasks: make a QR code for the guest Wi-Fi, invent a password that is actually strong, work out someone's exact age, convert cups to milliliters, figure out what time the meeting is in another country. None of these deserve an app install. Eight small tools here handle them in seconds, entirely in your browser.
QR Code turns any link, text, or Wi-Fi credential into a scannable code you can download and print — restaurant menus, event posters, business cards. Password Generator builds strong random passwords with configurable length and character sets; because it runs offline, the password never touches a server. BMI Calculator and Age Calculator answer the health and paperwork questions instantly — the age tool counts years, months, and days, which matters more than expected on official forms.
Date Calculator adds or subtracts days from a date, counts working days between two dates, and finds the weekday of a future deadline. Unit Converter handles length, weight, volume, temperature, area, and speed — cooking conversions, travel distances, furniture measurements. Time Converter and Random Number round out the set: timezone math for remote teams, and fair draws for giveaways or decision-making.
How to choose: it is less about choosing and more about bookmarking — these are the tools people pin and return to. Practical tips: generate passwords at 16+ characters with symbols for anything that matters, and never reuse them; make Wi-Fi QR codes with the password embedded so guests connect with one scan; and when converting units for baking, convert weight rather than volume wherever possible — it is more precise.
Everything here is free, works on mobile, and sends nothing to any server. The tools remember nothing between visits, so each use starts fresh.
Frequently asked questions
Are the generated passwords stored anywhere?
No. Password Generator runs offline in your browser using your device's random source, and the result is never transmitted or saved. Refresh the page and it is gone — copy it straight into your password manager.
Do the QR codes I create expire?
No. The QR image encodes your content directly, so it works for as long as the content itself is valid. That is why Wi-Fi and contact codes you print keep working years later.
Which unit categories does the converter support?
Length, weight, volume, temperature, area, speed, and data size. For cooking, prefer weight conversions over volume for accuracy.
