Tiny Tiny Tools

Small tools, thoughtfully made

About Us

Tiny Tiny Tools is a growing collection of free, focused utilities for everyday tasks. We build calculators, image and PDF tools, text utilities, and converters.

Why we built it

Simple tasks should not require complicated software. Each tool is designed to be easy to understand, quick to open, and useful without creating an account.

Browser-first by design

Where practical, processing happens locally in your browser. This keeps tools responsive and reduces the need to send the files or values you are working with to an application server. Learn more in our Privacy Policy.

Useful for more people

We aim for clear language, keyboard-friendly controls, strong contrast, and responsive layouts. Read our accessibility commitments.

Who operates Tiny Tiny Tools

I'm Sagar Limbu, and I build and maintain Tiny Tiny Tools myself. The site is operated by Brandghar Private Limited, a company registered in Nepal with its office in Kupondole, Lalitpur. The company is the legal publisher; the code, the copy, and the formulas are mine.

This is a one-person project, and I'd rather say so than imply a team. The honest trade-off: fixes can take longer than they would at a company with a support rota, and I don't work weekends reliably. What you get in exchange is that one person reads every email sent to hello@tinytinytools.com, and that person can change the code the same day.

How the tools are built and checked

I'm a developer, not an accountant, a tax adviser, or a clinician. So I don't ask you to trust my judgment on money or health — I show you the arithmetic instead. Every calculator on this site names the formula it uses, the assumptions behind it, what it deliberately excludes, and the published source the rule came from. If you disagree with a result, you should be able to find exactly where our numbers diverge.

In practice that means tax figures trace to IRS publications, unit conversion constants to NIST, and health formulas and their category ranges to the CDC or NIH. Where a rule changes by year, the page states the year it models. Financial and health outputs are estimates for planning, never advice for a decision — the disclaimer sets out the limits.

Calculation logic lives in typed modules covered by unit and boundary tests, and the worked examples on each page are checked against the same code the tool runs. A review date on a page means I checked it on that date; it is not a certification.

Every file tool runs entirely in your browser. Selected files are not uploaded to Tiny Tiny Tools or sent to a third-party processing API — you can confirm that yourself in your browser's network tab, which is a better assurance than anything I could write here.

Open source

Where a piece of that browser-side code is useful on its own, I publish it. strip-image-metadata (npm) is the metadata reader and stripper behind the EXIF remover: it reads the GPS coordinates, camera serial and timestamp out of a JPEG, PNG or WebP and removes them without re-encoding the picture. MIT licensed, no dependencies, and it runs the same in Node as it does in a browser.

Publishing it is partly self-interest. A privacy claim you can read the source of is worth more than one you have to take on trust, and code that other people compile into their own projects gets bugs reported that a closed tool never would.
