What this QR code generator does

A QR code is a square pattern that a phone camera turns back into text. What happens next depends on that text: a web link opens in the browser, a Wi-Fi code offers to join the network, a contact card offers to save a new contact, and a tel: code offers to call. This tool writes the text in the right format for each job, draws a styled QR code from it, and lays it out on a poster you can print.

It is useful for almost anyone in India who deals with the public: a cafe sharing its guest Wi-Fi, a PG owner putting the network details on each floor, a real estate agent printing a contact QR on visiting cards, a coaching centre linking its admission form, a wedding family sharing the venue location, or a shop owner putting its website on a carry bag.

Everything is made in your browser. Nothing you type, not even a Wi-Fi password, is sent to a server, and the code works without any account or subscription.

How to make a QR code

1. Pick what the code should do: Website, Text, Wi-Fi, Contact card, Email, SMS, Phone call, Location or Event.
2. Fill in the details. The text that goes inside the QR is shown under the preview, so you can check it.
3. Edit the poster heading and sub-line, for example "Scan to connect to Wi-Fi" or "Scan to see our menu". The name line fills itself from your details, and you can change it.
4. Choose a design: a poster, a fold-in-half table tent, a counter stand, a square sticker or a card. Pick colours, a dot style and a centre icon, or upload your own logo.
5. Choose Download PDF for real print sizes on A4 paper (an A4 poster or table tent, A5, A6 stand inserts, stickers or cards, with cut lines), or download the poster as a PNG. Switch to "QR only" for the bare code as a PNG (600, 1200 or 2400 px), an SVG, or a sheet of 50 or 75 mm QR stickers.
6. Scan it with two different phones, then print.

What goes inside each type of QR code

Phones only act on a QR code if its text follows a known format. These are the formats this tool uses:

The Wi-Fi, SMS and geo formats are the ones described in the ZXing barcode contents guide, which most scanner apps follow. In a Wi-Fi code, the characters \ ; , : " in the network name or password must be escaped with a backslash; the tool does this for you, so a password like chai;2026 still works. Contact cards follow vCard 3.0 (RFC 2426), and mobile numbers are saved with the country code (+91 by default) so they work even when the person scanning is abroad.

Website QR codes

Type the address with or without https://; the tool adds it if it is missing. Use the final address rather than a link shortener, so the code keeps working even if the shortening service stops. If the page might move later, point the code at a page on your own website and keep that page up to date.

Location QR codes

Paste a map link from your browser's address bar, type the coordinates (for example 28.6129, 77.2295), or tap "Use my current location" while standing at the place. The "Map link" option builds a standard map search link that opens in the browser or a maps app on any phone. The "geo:" option hands the coordinates to the phone's default map app instead. A short share link from the map app (such as maps.app.goo.gl) has no coordinates inside, so the tool puts the link itself in the QR; it still opens the place on any phone with internet.

Event QR codes

The event type stores the name, start and end time, venue and a note. Some phone cameras open it straight into the calendar, while others show the details as text, so print the date and time on the poster as well. This is handy for a society function, a school annual day or a wedding reception.

Tips for a QR code that always scans

• Dark on light. Use dark dots on a white or very light background. Inverted codes (light dots on dark) fail on some scanners.
• Give it room. The white border around the code (the quiet zone) is part of the code. Do not crop it or print text right up to the edge.
• Size for the distance. A code on a visiting card is scanned from a few centimetres away; one on a shop board may be scanned from a metre or more. Bigger distance needs a bigger print.
• Less text, easier scan. A long paragraph makes a dense pattern with tiny dots. Keep text codes short, or put long content on a web page and link to it.
• Logos with care. A small, simple logo in the centre is fine because the code then uses the highest error correction. Do not cover the three large corner squares.
• Test before you print fifty. Scan the final file on an Android phone and an iPhone, in normal shop lighting.

Common mistakes

• Wrong Wi-Fi name. The network name is case-sensitive. "Sharma Cafe" and "sharma cafe" are different networks.
• Old details. A changed phone number or Wi-Fi password makes every printed copy useless. Make a new code and replace the old prints.
• Using a screenshot. Screenshots are often blurry when printed. Download the PNG or SVG instead.
• Brand logos. Do not add other companies' logos to your poster unless you have permission. The icons in this tool are plain, generic shapes.
