58 free tools for everyday questions — no sign-up, no clutter
Tools In Orbit is a free collection of small web tools that each do one job well: convert a unit, check a loan payment, format a JSON file, compress a photo, or just find out your zodiac sign and life path number. Every tool opens instantly on a phone or a computer and works without an account.
Most tools run entirely in your browser, so the numbers, text and images you enter never leave your device. Each tool page explains the formula or method behind the result, with tips and answers to common questions, so you can see how a number was calculated instead of trusting a black box.
The swirling orbit above shows every tool at once — tap any icon for a quick preview. If you prefer a plain list, here is everything grouped by what it helps you do.
