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 base64 encode / decode

  1. Type or paste your input into the box above.
  2. The result updates instantly as you type in most text tools — no button to press.
  3. Use the copy button to take the output exactly as shown.
  4. Your text never leaves your device, so it is safe for drafts and snippets.

About this tool

Base64 represents binary data as safe text — used in data URIs, email attachments, JWTs and APIs. Encode any text (full Unicode/Urdu supported) or a small file, and decode Base64 back to readable text.

Note: Base64 is an encoding, not encryption — anyone can decode it. Never use it to “hide” passwords.

Frequently asked questions

Why is Base64 output ~33% longer?
It packs 3 bytes into 4 characters from a 64-character alphabet — the size increase is built into the format.
Can I convert an image to Base64?
Yes — use the file option to get a data URI you can paste into HTML or CSS.
Does decode handle Urdu/emoji?
Yes, text is handled as UTF-8, so Urdu, Arabic and emoji round-trip correctly.

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).
