ToolsKit is an independent website that offers free online utilities: calculators for tax, discounts, margins, attendance, marks, grades and dates, plus tools for text, images, PDFs and JSON.

Why we built it

Many online tools ask you to upload files, create an account or click through cluttered pages. We wanted tools that are quick, readable and respect your privacy, so every tool on this site runs inside your browser.

How we write our tools

• Every calculator uses a formula that is shown on its page, with a worked example.
• We test tools with valid and invalid inputs, including boundary cases such as leap days and zero values.
• Pages explain limits, for example that grading systems and conversion formulas differ between institutions.

Who runs this site

ToolsKit is operated by the site owner of toolskit.store. You can reach us at contact@toolskit.store or via the contact page.

Corrections and suggestions

If you find a mistake or want a new tool, please write to us. We review reports and update pages when a formula, rate or explanation needs correcting.

Funding

The site is free to use. We may show advertising in the future to cover hosting and development; ads are always kept separate from tool controls. See the Privacy Policy.
