About Eliroo
Small, fast tools for the questions that come up in the middle of something else, and a promise that they stay free.
What Eliroo is
Eliroo is a growing collection of single-purpose tools for the jobs that interrupt your day: a conversion, a percentage, a date difference, a code that will not scan, a paragraph that needs counting. Each one does its job on a single page, answers as you type, and gets out of the way.
Free, and staying free
Every tool is free forever. No account, no usage limits, no trial that quietly ends, no paid tier waiting to appear once enough people rely on it. Display advertising covers the running costs, and the ads stay out of the working area: never above a tool, never between what you typed and the answer, and always in a slot with a fixed size so the page cannot jump while you are reading it.
Install what you use
Any tool here is installable on its own. If the only one you ever need is the kilograms converter, that is what goes on your home screen, opening straight into the tool rather than into a site you then have to navigate.
Who makes it
Eliroo is built and run by Elipix, a small software company based in Finland. No investors and no growth team, just people who got tired of every simple tool wanting an email address first. If you want to reach a person about anything on this site, contact goes to that person directly.
What makes them different
Two things. They are quick: results appear as you type, with no submit button and no results page. And they are free forever, with no account, no usage limits and no paid tier waiting once you rely on one. Every tool also installs on its own, so the one converter you open twice a day can live on your home screen instead of in a bookmark folder.
The trade-offs
Building this way is not free. A few things are genuinely hard or impossible: very large video files, anything needing live data such as currency rates, anything behind a licensed database. Where a tool cannot be built honestly it does not get built, and the ones that do exist say plainly what they cannot do.
How tools get built
Most new tools come from requests. If something is asked for more than once it usually gets built within a few weeks, so if the tool you needed is missing,tell us what you were trying to do. That is more useful than the name of the tool, because it often turns out an existing one already does the job.
Corrections
Some of these tools state facts: conversion factors, formulas, definitions. If you find one that is wrong, please tell us. It gets fixed and the page notes what changed.
