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 heic to jpg converter

  1. Add your image using the upload box or drag and drop. Your file stays on your device — it is never uploaded.
  2. Choose your settings (target size, format or dimensions).
  3. Check the live preview and the before/after file sizes.
  4. Download the processed image. That is it — no account, no watermark.

About this tool

iPhones save photos as HEIC, which many websites, Windows PCs and application portals refuse. This tool decodes HEIC/HEIF files locally (using the open-source heic2any decoder) and re-encodes them as standard JPG.

Your photos never leave your device during conversion.

Frequently asked questions

Why can't portals open my iPhone photos?
HEIC is Apple's efficient format, but support outside Apple devices is patchy. JPG works everywhere.
Does it work for Live Photos?
It converts the still image from the HEIC file. The motion part of a Live Photo is not included.
Can I stop my iPhone saving HEIC?
Settings → Camera → Formats → “Most Compatible” switches future photos to JPG, at the cost of larger files.

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).
