About UsefulTools

UsefulTools is a collection of 182+ small, useful tools — random generators, file converters, calculators, image and PDF utilities, text tools and more. The idea is simple: when you need a quick job done, you shouldn't have to install an app, create an account, or wonder who is looking at your files.

Everything runs on your device. The site is a set of static pages; every tool is JavaScript executed by your own browser. Images you convert, PDFs you split, passwords you generate and text you paste are never uploaded to a server — the site has no upload backend at all. This makes the tools fast, private, and free to run.

Free, forever. There are no paywalls, accounts, daily limits or watermarks. If the site shows ads in the future, they will only ever cover hosting costs — never at the expense of tool quality or your privacy.

Built to last. Because the entire site is static, it can be hosted anywhere and will keep working even under heavy traffic. Bookmark your favorite tools — they are not going anywhere.
