All Free Online Tools

All tools on ToolBase are completely free to use with no account, no subscription, and no usage limits. Calculation tools (age, date, percentage, number to words, word counter) run entirely in your browser. The Grammar Checker sends text to an external analysis engine that does not store your data. The Screenshot to Document tool uses in-browser OCR — your images never leave your device.

Tools are designed for students, professionals, and anyone who needs fast, reliable calculations and text tools without paying for premium subscriptions. Whether you're checking grammar before a job application, converting numbers for a bank cheque, calculating your exact age for a visa form, or extracting data from a screenshot — each tool focuses on doing one thing very well.

New tools are added regularly. If there's a utility you'd like to see, let us know.

About these free tools

Every tool on this page is completely free to use without creating an account, installing anything, or agreeing to a trial period. There are no usage limits, no daily caps, and no premium version hiding features behind a paywall. Open the tool, use it, close the tab — that is all there is to it.

Most tools run entirely within your browser. Your text, numbers, and images are processed locally on your device and never transmitted to any server. The Grammar Checker is the one exception — it sends your text to an external grammar analysis engine that does not store it. The Screenshot to Document tool uses in-browser OCR, so your images never leave your device.

The tools are built for the tasks that come up constantly in everyday work and study: checking grammar before submitting an assignment, counting words against a limit, converting a number to words for a bank cheque, calculating an exact age for an official form, figuring out days between two dates, or extracting data from a screenshot someone sent on WhatsApp. These are not novel problems — but finding a tool that handles them cleanly, without requiring registration or payment, is harder than it should be.

Frequently asked questions

Are these tools really free?

Yes, completely. The site is supported by Google advertising, not by charging users. There are no hidden fees, no free tier with a paid upgrade, and no expiring trial periods.

Do I need to create an account?

No account is required for any tool. Open the tool, use it, and close the tab. Nothing is stored between sessions.

Is there a word limit on the Grammar or Plagiarism Checker?

There is no hard word limit set by ToolBase. Very large texts may take longer to process depending on your device and internet connection, but there is no artificial cap.

Do the tools work on mobile?

Yes. All tools are designed to work on both desktop and mobile browsers. The layout adjusts to smaller screens and all functionality is available on phones and tablets.

What happens to my data?

Calculation tools (Age Calculator, Date Difference, Percentage, Number to Words, Word Counter) process everything locally — no data leaves your browser. The Grammar Checker sends your text to an external API for analysis; that service does not store the text. The Screenshot to Document tool runs OCR in your browser; your image is never uploaded anywhere. See our Privacy Policy for full details.
