What is a QR code?
A QR (Quick Response) code is a two-dimensional barcode that stores information — a website link, a phone number, WiFi credentials, plain text — as a pattern of black and white squares. Any modern smartphone camera can read it: point the camera at the code, and the phone shows a notification that opens the link or connects to the network. No app is needed on Android or iPhone.
QR codes were invented in 1994 for tracking car parts in Japan, but the smartphone era turned them into the fastest bridge between the physical and digital world. In Pakistan they exploded in popularity after 2020: restaurant menus, JazzCash and easypaisa payment counters, event tickets, electricity bills and even rickshaw advertisements now carry QR codes. The codes you create with this tool are static — the data is baked directly into the pattern, so they never expire, never redirect through a third-party server, and keep working forever at zero cost.
How to use this generator
- Pick a QR type. Choose URL/Text for websites, Google Maps locations, payment links or any text; WhatsApp to let people start a chat with your number (with an optional pre-filled message); or WiFi so guests can join your network with one scan.
- Enter your details. The preview updates instantly as you type — there is no "generate" button to press.
- Style it. Change the foreground and background colors to match your brand, select a size, and upload a logo if you want one in the center. We automatically raise the error-correction level so a logo doesn't break scanning.
- Download. Grab a PNG for screens and everyday printing, or an SVG vector file for large-format printing like banners and signboards. Always scan the final printout once with your own phone before distributing it.
Popular QR code use cases in Pakistan
- Restaurant and café menus. Print a QR linking to your menu PDF or Google Drive file on table tents. Customers scan instead of handling shared menus, and you can update prices without reprinting.
- Business cards and shop counters. A WhatsApp QR on your visiting card or counter lets customers message you instantly — no typing numbers, no mistakes. Combine it with our WhatsApp link generator for click-to-chat links you can also share online.
- JazzCash, easypaisa and Raast payments. Encode your payment link, till ID or account details so customers can pay without dictating numbers across the counter. Small shops across Karachi, Lahore and Islamabad already do this daily.
- WiFi sharing at homes, offices and guest houses. Stick a WiFi QR near the entrance and guests connect without asking for the password — especially handy for long, complex passwords.
- Lost-and-found tags. This is what we do at Nishaaan: a QR tag on your luggage, pet collar, bike or keys lets any finder scan and contact you anonymously — without exposing your phone number. See how a QR tag works.
- Marketing, flyers and CVs. Link printed material to your website, portfolio, location pin or social profiles. A QR turns a static flyer into a measurable digital touchpoint.
Printing tips for reliable scanning
- Keep strong contrast. Dark code on a light background scans best. Avoid yellow-on-white or light-grey combinations.
- Mind the size. A good rule of thumb: minimum 2 × 2 cm for close-range scanning, and roughly 1 cm of QR width for every 10 cm of scanning distance for posters and banners.
- Leave a quiet zone. Keep a white margin around the code — our downloads include one. Don't crop it off in your design.
- Never stretch. Resize proportionally only. A squashed QR code may not scan at all.
- Use SVG for big prints. Vector files stay razor-sharp at any size — ideal for shop signboards and event banners.
- Outdoor durability matters. Paper QR codes fade and tear in rain and sun. For anything attached to your belongings — luggage, pets, vehicles — a laminated or metal QR tag like a Nishaaan tag survives the Pakistani weather and keeps working for years.
Frequently asked questions
Is this QR code generator really free?
Yes, completely free. There is no signup, no watermark, no expiry and no limit on how many QR codes you create. The QR codes are generated in your browser and belong to you forever.
Do the QR codes expire?
No. These are static QR codes — the data (your URL, WhatsApp link or WiFi details) is encoded directly into the pattern. They never expire and never stop working, no matter how many times they are scanned.
Can I add my logo to the QR code?
Yes. Upload any image (PNG, JPG or SVG) and it will be placed in the center of the QR code. We automatically use a high error-correction level so the code still scans reliably with a logo.
Should I download PNG or SVG?
Use PNG for websites, WhatsApp Status, social media and most printing. Use SVG when a printer or designer asks for a vector file — SVG scales to any size (banners, billboards, signboards) without losing sharpness.
Can I make a QR code for my JazzCash or easypaisa payments?
Yes. Generate your payment link or Raast/IBAN details as a URL or text QR code, or use the WhatsApp tab so customers can message you to confirm payment. Many small shops in Pakistan print such codes at the counter.
What is a WiFi QR code and how does it work?
A WiFi QR code encodes your network name (SSID), password and encryption type in the standard WIFI: format. When a guest scans it with their phone camera, the phone offers to join the network automatically — no typing the password. It works on both Android and iPhone.
Is my data uploaded to your server?
No. The QR code is generated entirely inside your browser using JavaScript. Your links, WiFi passwords and logo images never leave your device.
Why do some QR codes fail to scan after printing?
The most common reasons are low contrast (light colors on light backgrounds), printing too small (keep at least 2 x 2 cm), or stretching the image. Keep dark foreground on a light background and test with a phone before mass printing.
