About Us

Qwikora (Simple Tools. Smarter Everyday.) is a growing set of free online tools for everyday jobs: working out a loan instalment, adding GST, counting the days between two dates, merging a PDF or shrinking a photo. There are currently 15 tools, and each one is built to do one thing clearly.

You do not need an account. Open a tool, enter your values or choose a file, and get the result.

• Simple. One tool, one screen, clear labels and plain-English explanations.
• Free to use. No sign-up and no paywall. If the site shows advertising, it is clearly labelled and kept away from the tool itself.
• Privacy-conscious. The tools run in your browser, so your files and text are not uploaded to Qwikora servers. Optional analytics or advertising cookies only load after you agree. Details are in the Privacy Policy.
• Honest about results. Calculators show the formula behind the answer, and the Disclaimer explains what the results are and are not.

Browse by category, or see every tool on the All Tools page.
