About ToolsFiesta

ToolsFiesta is a growing collection of free online tools for everyday tasks — calculators for loans, savings and percentages, tools for writers, and utilities for developers. Each tool is designed to do one job well, load quickly and give clear, accurate results.

Why we built it

Many tool websites are slow, cluttered or ask you to sign up before you can use them. We wanted the opposite: simple pages that open instantly on any device, explain how each result is calculated, and respect your privacy.

Your privacy comes first

Our tools run in your web browser. The numbers and text you enter are processed on your own device and are not uploaded to our servers. You can read more in our Privacy Policy.

How the site is funded

ToolsFiesta is free to use and supported by advertising. Ads help pay for hosting and the time it takes to build and maintain new tools. We aim to keep ads unobtrusive and never let them get in the way of the tools themselves.

Accuracy

We test every tool carefully and describe the formulas we use on each page. Even so, results are provided for general information only. For important financial, legal or medical decisions, please confirm results with a qualified professional.
