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.

Terms of Use

Use of the tools

GenApps provides free online tools for personal and business use. You may use the output (compressed images, PDFs, invoices, QR codes and so on) for any lawful purpose.

Estimates, not advice

Calculator results are estimates based on standard formulas and the inputs you provide. They are not financial, tax, legal or medical advice. Loan terms come from your bank, tax obligations from your tax authority, and health decisions from your doctor.

Your content

Files you process remain yours. Because processing happens on your device, GenApps never receives, stores or claims any rights over your content. You are responsible for having the rights to any material you process (for example, YouTube thumbnails belong to their creators).

Availability

Tools are provided “as is” without warranties. We may add, change or remove tools at any time.

Acceptable use

Do not use GenApps for unlawful purposes, to infringe intellectual-property rights, or to attempt to disrupt the service.
