Free tools

There are 91 free tools on Tools, grouped by category: loan and EMI, investment, savings and government schemes, interest, tax and salary, retirement and pension, returns, trading, PDF and image, exam and education, health and pregnancy, career, business documents, text tools, code minifiers, developer tools, WhatsApp tools and everyday utilities.

Yes. Every tool on Tools is free to use, and each is marked Free.

No. The tools work without an account and without signing in. Just open a tool and use it.

No. The PDF, image and document tools do the work in your own browser, on your device. Your files are not uploaded to Ur Next Door or anywhere else, and each page that takes files says so.

No. The tools run in your browser. What you type, such as salary, loan amounts, tax details or the details on an invoice or receipt, is not sent to Ur Next Door and is not stored. A document generator makes its PDF in your browser tab.

Some tool pages load chart or PDF libraries from a public content delivery network. That network sees your IP address and which page you are on, as with any file a page loads. Your own data and files still stay in your browser.

Yes, the first time you choose a file. The PDF tools load a free PDF library then. The file itself is still worked on in your browser and not uploaded.

Yes. The tools work on phones as well as on computers, in your phone's web browser.

Open Tools and look under the category, or type the tool's name or what you need, for example merge pdf or emi, in the site's search bar. Matching tools show in the results and under the Tools tab of the search page.

Each tool page also links to other tools in the same category.

Each tool page has the tool itself, an explanation of how it works with a worked example, and a short FAQ.

Use them for planning only. The figures are estimates, not tax advice, and the pages say so. The Income Tax Calculator, for example, does not handle capital gains and does not round figures the way a filed return does.

The Income Tax Calculator covers tax year 2026-27, FY 2025-26 and FY 2024-25, under the old or new regime, by age. Other tax tools name the year they use on their own page.

Not all of them. The Income Tax Calculator shows surcharge with its marginal relief. Where a tool leaves surcharge out, such as the Job Offer Comparison, the page says so.

No. They give estimates for general information, not medical advice or a diagnosis, and say so on the page. Talk to a doctor about your own health.

There is no exam photo and signature resizer, because exam sizes could not be checked against the official notices. Use the Image Resizer for a size in pixels, or the Image Compressor for a size in KB, as given in your exam's notice.

Image Compressor, Image Resizer, JPG to PDF, Merge PDF, Split PDF and Compress PDF.

Yes. There is a GST invoice generator, a rent receipt generator, a quotation generator and a salary slip generator. Each is downloaded as a PDF.

The Age Calculator, which can also give your age on a given date, the Percentage Calculator, which also works out marks, and CGPA to Percentage.

For practice tests, see Test series.

Pregnancy due date, pregnancy week by week, ovulation, baby age, with corrected age for premature babies, and BMI.

Under Career and Jobs there is a notice period calculator, a salary hike calculator and a job offer comparison. Under Tax and Salary there are salary, HRA, gratuity and income tax calculators.

Loan and EMI calculators (including home, car, personal and education loans, prepayment and eligibility), investment (SIP, lumpsum, SWP, mutual fund, step-up SIP, XIRR and more), savings schemes (PPF, EPF, FD, RD, NSC, Sukanya Samriddhi, Post Office MIS, SCSS), interest, tax and salary, retirement and pension, returns and trading. See them all on Tools.

A JSON formatter, a code compiler, a JWT decoder, Base64 and URL encoders, a regex tester, a diff checker, a UUID generator, a Unix timestamp converter and a password generator, plus 7 code minifiers for HTML, CSS, JavaScript, JSON, XML, SVG and SQL.

No. The minifiers remove only spaces and comments that do not change what the code does. Text inside strings and attribute values is kept exactly, JSON numbers keep every digit, and JavaScript without semicolons still runs.

A WhatsApp link generator, a WhatsApp number validator, a WhatsApp QR code generator and a WhatsApp message formatter.

Text tools: word counter, case converter and remove line breaks. Everyday: a QR code generator for links, text, Wi-Fi and UPI payment, a unit converter and a date difference calculator.

The calculators work only from the numbers you type, so the result is an estimate, not an offer. A lender's figure can differ because it adds charges a calculator leaves out, such as tax on the processing fee, insurance or a prepayment fee, and because each lender uses its own rules and checks.

Check your loan agreement or ask your lender for the final figure.

The tools now live on the main site at Tools, at urnextdoor.com/tools.
