About ClickZM

What ClickZM is

ClickZM is an independent website with 379 free tools: PDF and image tools, text and SEO utilities, developer tools, unit converters, finance and tax calculators, network tests such as the internet speed test, and more. There is no account and no sign-up.

Each tool page starts with a short answer to the question people search for, then the tool, the steps to use it and the questions people ask most. The site is available in English, Spanish, French, German and Hindi, and as an Android app on Google Play.

Where your files and data go

• In your browser: PDF, image, audio, video, text and calculator tools. Files are read and processed on your device and are not uploaded to ClickZM.
• On ClickZM's server: website, SSL, WHOIS (RDAP), port and IP checks, because a browser cannot run them. Only the address you enter is sent.
• Public services: DNS tools ask public DNS-over-HTTPS resolvers. The speed test measures against Cloudflare's network or ClickZM's server. AI tools send the text you enter to Anthropic's Claude to produce the answer.

The privacy policy lists every case in detail, including analytics and advertising.

How the tools are checked

Every release is checked with automated tests for the calculations and file tools, and the PDF and image tools are run on realistic sample files before they go live. Worked examples on the pages (for example, ₹5,000 a month for 10 years at 12% in the SIP calculator) are checked by an automated test against the formula shown on the page.

If a result looks wrong, tell us with the inputs you used. Confirmed errors are fixed and the page is updated.

Finance and tax content

Calculators that touch money show the formula they use on the page, so you can check the result yourself. Rules and rates come from official or primary sources:

• India income tax: the FY 2026-27 slabs and rules published by the Income Tax Department.
• India GST: the rate slabs notified by the GST Council.
• Small-savings schemes such as PPF: the rates announced by the Ministry of Finance each quarter.
• US sales tax: Tax Foundation state rates as of 1 January 2026.

These pages are reviewed when the rules change, such as a new budget or a quarterly rate revision. Every result is an estimate for planning. It is not financial, tax or legal advice; for a decision, check with your bank, a tax professional or the official source.

Ads and affiliate links

ClickZM is free because it shows ads and some affiliate links. They never change a calculation or a result, and the tools work the same with an ad blocker.

Translations

Pages in Spanish, French, German and Hindi are translated from the English originals. If a translation reads badly or is wrong, please let us know.
