About Useful Daily Tools
A comprehensive collection of free, simple, and powerful online tools designed to help developers, writers, students, and professionals accomplish everyday tasks quickly and efficiently.
Our Mission
We believe that everyone should have access to useful tools without complexity. Our mission is to provide a clean, fast, and user-friendly platform where you can find the tools you need without signing up or downloading software. The site is supported by optional, consent-based advertising: nothing loads unless you explicitly allow it, and every tool works fully if you decline.

Privacy & Security
All tools run entirely in your browser. Your inputs are never sent to a server or stored anywhere. Analytics and advertising only run if you explicitly opt in through the consent banner, and you can change your mind at any time via the cookie button.
Technology
Built with Eleventy (11ty), a modern static site generator, along with vanilla HTML, CSS, and JavaScript. This ensures compatibility, speed, and a lightweight experience.
How Our Tools Work
Every tool on this site runs as JavaScript inside your own browser. When you count words, format JSON, or merge a PDF, the work happens on your device and the result is created there. Nothing you type or upload is sent to our servers, because the site has no backend that could receive it.
- PDF tools use pdf-lib, an open-source library that reads and writes PDF files directly in the browser.
- Calculators use the standard published formulas (for example the amortization formula for loan EMIs and the compound interest formula A = P(1 + r/n)nt), and each tool page explains the method it uses.
- Generators such as the password and UUID generators use your browser's cryptographically secure random number generator (the Web Crypto API).
How the Site Is Funded
Useful Daily Tools is free to use and has no paid tier. It is supported by advertising, which only loads if you accept it in the cookie settings. If you decline, every tool still works exactly the same.
Corrections and Feedback
If a tool gives a wrong result or a page explains something incorrectly, please tell us through the contact page. Reported problems are checked and fixed, and the explanations on tool pages are updated when a tool's behavior changes.
