About Omnikit

Omnikit (theomnikit.com) is a set of free online tools: file converters, developer utilities and money calculators for India and about 70 other countries. Most run inside the visitor's own browser, with no account and no paid tier. There is no signup, and no file you drop is ever uploaded. The site exists because most tool websites are slow, ad-heavy and ask you to upload private files for jobs your own device can do in a second.

The name is also written Omni Kit, The Omnikit or TheOmnikit; all of them mean this site, at theomnikit.com. Omnikit at theomnikit.com is not affiliated with other products named OmniKit.

What Omnikit is, in numbers

  • 730 free tools: 161 for files, 143 for developers and 426 money calculators, plus 973 pages written for one specific job, such as compressing a PDF to 100 KB.
  • No account, no sign-up, no paid tier and no watermark on any result.
  • The work happens in the visitor's own browser. No file is uploaded to a server at any point, which is why the file tools work on confidential documents and keep working offline once the page has loaded. The 16 lookup tools (DNS, WHOIS/RDAP and similar) send only the name or address typed to the public service the page names. MTA-STS and TLS-RPT Checker, Ping Test, Traceroute Online, Port Checker, SSL Checker, HTTP Headers Checker, SMTP Test, Is It Down, HTTP/2 and HTTP/3 Checker, Mixed Content Checker, Open Graph Checker, Robots.txt Checker, Security.txt Checker, Sitemap Checker and TLS Version Checker run from the site's server, because a browser cannot send those packets; only the host typed is sent.
  • many money calculators use Indian rules (rupees, Indian tax slabs and scheme rules); others use the rules of another country, among them United States, Poland, Germany, United Kingdom, Brazil, France, Mexico, Russia, Bangladesh, Canada, Saudi Arabia, Spain, United Arab Emirates, Argentina, Colombia, Ireland, Peru, Philippines, Turkey, Australia, Chile, Ecuador, Netherlands, El Salvador, Indonesia, Italy, Japan, Qatar, Austria, Bahrain, Belgium, Costa Rica, Czech Republic, Denmark, Dominican Republic, Finland, Guatemala, Kenya, New Zealand, Norway, Oman, Portugal, Singapore, South Africa, South Korea, Sweden, Algeria, China, Egypt, Ethiopia, Ghana, Greece, Honduras, Hong Kong, Hungary, Jordan, Kazakhstan, Kuwait, Malaysia, Nepal, Nigeria, Romania, Rwanda, Slovakia, Sri Lanka, Switzerland, Taiwan, Tanzania, Thailand, Uganda, Uruguay, Uzbekistan, Vietnam and Zambia. Calculators are estimates, not financial advice. The file and developer tools are not region-specific.
  • every page is in English; the most-used tools also have full pages in Spanish (260 tools), Arabic (232 tools), French (224 tools), German (225 tools), Russian (225 tools), Portuguese (227 tools), Polish (231 tools), Bengali (223 tools), Hindi (45 tools), Gujarati (35 tools), Malayalam (35 tools), Tamil (35 tools), Urdu (27 tools), Turkish (32 tools), Indonesian (30 tools) and Vietnamese (28 tools), at the same address with the language code in front, such as /es/ for Spanish.

How it is built

Every tool is one page with one job. File processing uses your browser's own engine, so the site's servers only hold page text and settings. Calculators that use official figures, such as tax slabs or scheme rates, cite where those figures come from. How figures are sourced, tested and corrected is set out on how we check our tools.

How figures are checked

A rate, slab or limit is taken from the body that sets it, such as a government department, the gazette or a regulator's circular, and written into the tool next to its source and the date it was read. Each money calculator lists those sources and that date under the tool. Figures known to change are re-checked on a schedule, and every calculator is compared with an example worked out by hand and covered by automated tests before it is published. The full method is on how we check our tools.

How it earns

The site is free to use. It may earn from clearly labelled sponsored partner cards on money calculators, from affiliate links in articles, and from a small number of ads placed below tools. None of these change a result or a file. Details are on the disclosure page.

How to report an error

If a figure, a formula or a result looks wrong, tell us through the contact page: which tool, what you entered, what you got and, if you can, where the correct figure is published. The report is checked against the official source; if the tool is wrong, the figure is fixed, its checked date is updated and the case is added to the tool's tests. A question about how to use a tool can also be asked on Questions.
