Why people use GenApps

Most tool websites upload your files to their servers, queue them, and sometimes keep copies. GenApps is built differently: every tool runs with JavaScript directly in your browser. Your passport photo, your PDF and your invoice data never leave your device — which is why the tools are instant, work on slow connections, and stay free.

The collection focuses on jobs people actually search for: compressing a photo to the exact kilobyte limit an application form demands (FPSC and PPSC want ≤30 KB, NADRA ≤50 KB), making a correctly sized passport photo at home, working out a loan EMI before visiting a bank, generating a GST-ready invoice, or checking a typing speed before a government job test.

Frequently asked questions

Are these tools really free?
Yes — every tool is free with no sign-up, no watermark and no daily limit. The site is supported by advertising, which is why we can keep file processing free.
Are my files uploaded anywhere?
No. Image compression, PDF merging, photo making and everything else happens locally in your browser. You can even disconnect from the internet after the page loads and the tools still work.
How accurate are the calculators?
They use the standard published formulas (reducing-balance EMI, compound interest, Naegele’s rule for due dates, Mifflin–St Jeor for calories) and show results to two decimals. They are planning estimates — for loans, taxes and health decisions, confirm final figures with your bank, tax authority or doctor.
Can I use these tools on my phone?
Yes. Every tool is mobile-first and works in any modern phone browser — useful when a form deadline hits and you only have your phone.

How to use the age calculator

  1. Enter your numbers in the fields above — use the exact figures from your loan, investment or bill for the most useful result.
  2. Press Calculate (most GenApps calculators also update as you type).
  3. Read the headline result together with the breakdown below it — totals, interest and schedules are shown, not just one number.
  4. Change any input and calculate again to compare scenarios side by side.

About this tool

Enter a date of birth to get an exact age in years, months and days, the weekday you were born, your total days (and hours) lived, and a countdown to your next birthday.

Handy for application forms that ask for age “as on” a specific date — change the “age at date” field to any cutoff date used by FPSC, PPSC, universities or employers.

Frequently asked questions

How do I check my age on a specific date?
Set the second date field to the cutoff date (for example the closing date of a job advertisement) and the tool calculates your age as on that date.
Why do forms reject my age?
Many government forms count age in completed years on the closing date. If you turn the limit age even one day before the cutoff, you may be over-age — this calculator shows the exact day count.
Is my date of birth stored?
No. The calculation happens in your browser and nothing is saved or sent anywhere.

Private by design

GenApps tools process everything locally in your web browser using JavaScript. Your files, photos and text are never uploaded to a server — close the tab and everything is gone. The only data our optional server features store is what you explicitly send us (a contact message, a tool rating or a newsletter email).
