A QR (Quick Response) code is a two-dimensional barcode that stores information in a grid of black and white squares. Unlike a traditional barcode, which can only hold a small string of numbers, a QR code can hold URLs, contact details, WiFi passwords, plain text, and more. When someone scans it with a smartphone camera, the encoded data opens instantly — no app installation required on most modern phones.

QR codes were originally developed in 1994 by a Japanese automotive company to track vehicle parts during manufacturing. Because they could be scanned quickly from any angle and held far more data than a standard barcode, they were soon adopted across retail, marketing, payments, and logistics. Today they appear on restaurant menus, product packaging, business cards, event tickets, and payment terminals worldwide.

Using this tool is straightforward:

• Type or paste the text, URL, phone number, or message you want to encode into the input box.
• Click "Generate QR Code."
• Your QR code appears instantly as an image.
• Click "Download PNG" to save it to your device.

The generated code is created fresh with each request and is not stored on our servers, so you can generate as many codes as you like without any usage limits.

Business and Marketing

Businesses print QR codes on flyers, posters, and packaging to link customers directly to a website, menu, or promotional offer. A shopper can scan a code on a product shelf and land on a page with more details, reviews, or a discount code, skipping the need to type a long URL by hand.

Contact Sharing

Instead of exchanging paper business cards, many professionals now share a QR code containing their name, phone number, and email. Scanning it lets the recipient save the contact directly to their phone in seconds.

WiFi Access

Cafes, offices, and guest houses often generate a QR code that encodes a WiFi network name and password. Guests scan it and connect automatically, without needing to type a complicated password.

Payments

Digital wallets and mobile banking apps across Nepal and South Asia rely heavily on QR codes for point-of-sale payments. A merchant displays a code, the customer scans it with their banking app, and the payment completes instantly — no card machine required.

Event Tickets and Check-ins

Concerts, conferences, and flights use QR codes as boarding passes or entry tickets. Each code is unique to the ticket holder, allowing staff to scan and verify entry quickly at the gate.

• Keep the encoded content short. Shorter text produces a simpler, easier-to-scan pattern. Long paragraphs of text create a denser code that can be harder for some cameras to read.
• Test before printing. Always scan your generated QR code with a few different phones before sending it to print, especially for large batches like posters or packaging.
• Leave a quiet zone. QR codes need a small margin of blank space around them to scan reliably — avoid cropping the image too tightly.
• Use high contrast. Black on white remains the most reliable combination. Avoid placing codes on busy backgrounds or low-contrast colors.
• Size matters for print. A code meant to be scanned from a few centimeters away (like a business card) can be small, but a poster meant to be scanned from across a room needs a much larger printed size.

Do QR codes expire?
No. A QR code generated by this tool encodes your data directly (this is called a "static" code), so it will work for as long as the image file exists and the underlying content (such as a website) remains valid.

Can I use this QR code for commercial purposes?
Yes, codes generated here are free to use for personal or business purposes, including printed marketing material and product packaging.

What's the maximum amount of text I can encode?
QR codes can technically hold thousands of characters, but for the most reliable scanning experience, we recommend keeping URLs and text under a few hundred characters.

Why won't my phone scan the code?
Make sure there's enough lighting, the code isn't blurry or too small on screen, and your phone's camera app supports QR scanning (most phones from the last several years do this natively without a separate app).

Is my data safe?
The text you enter is used only to generate the image in real time and is not saved on our servers after the code is created.
