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.

  3. Copy it with one click, or download it if the tool offers a file.
  4. Generate again as many times as you like — it is free and unlimited.

About this tool

Create QR codes for a website link, plain text, a Wi-Fi network (guests scan to join — no password typing), or a WhatsApp chat link for your shop. Choose a size and download a print-ready PNG.

These are static QR codes: they never expire and work offline because the information is encoded in the pattern itself.

Frequently asked questions

Do QR codes expire?
Static QR codes like these never expire — the data is inside the pattern. (Dynamic QR services that redirect through their servers can expire; these don't.)
What size should I download?
512 px is fine for screens and small prints; choose 1024 px for posters and shop counters.
Can I add my logo in the middle?
Not here — keep the pattern clean for reliable scanning. Print it as-is; scanners read it instantly.
Is it free for business use?
Yes, use the codes commercially — on menus, packaging, visiting cards and shop windows.

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).
