QR Code Generator – Make Free Custom QR Codes for Links, UPI, WhatsApp and Text
What does this tool do?
A QR code is a square barcode that a phone camera or a payment app can read in a second. This generator creates one for you, free and without signing up. It supports four types of content: a website link, a UPI payment request, a WhatsApp chat and plain text. You can change the colours, choose the image size and place your own logo in the centre, then download the QR as a PNG image or print it straight away.
The QR code updates live as you type, so you can see the result before you download it.
The four QR types
- Link / URL: opens a website, a Google Form, a social media page or any web address when scanned.
- UPI: opens a payment screen in a UPI app with your UPI ID (VPA) filled in. You can add an optional amount in rupees and a name, so customers only need to confirm and pay.
- WhatsApp: opens a chat with your number. You can add a default message, such as a greeting or an enquiry, which is filled in for the customer.
- Text: shows any short message, address or note when scanned.
How to use it, step by step
- Pick a tab: Link, UPI, WhatsApp or Text.
- Fill in the details for that tab (see the examples below).
- Choose the QR colour and background colour, or tap one of the quick themes (e-Mitra Blue, Navy Black, Green, Red).
- Select the quality: 400 px, 600 px (HD) or 1000 px (Ultra HD). Use the largest size if you plan to print on a banner or poster.
- If you want, upload a logo for the centre. Use the ✕ button to remove it.
- Click PNG Download to save the image, or Print to print it. Allow pop-ups in your browser if the print window does not open.
What to enter in each tab
Link: type the full address, starting with https://, for example https://www.example.com
UPI: your UPI ID in the form name@bank, an optional amount, and the name you want shown.
WhatsApp: your number with the country code and no plus sign or spaces. For an Indian number, write 91 followed by the 10 digits, for example 919876543210.
Text: keep it short. Very long text makes a crowded code that is harder to scan.
Supported formats and sizes
The QR is saved as a PNG image, in 400, 600 or 1000 pixel squares. The tool uses the highest error-correction level, which lets the code still be read even if a small part is covered. That is why a logo in the centre works. The downloaded file is named after the tab you used, for example Emitra_QR_UPI.png.
Where is it useful?
- Shops, CSC and e-Mitra counters: a UPI QR on the counter for quick payments.
- Visiting cards and posters: a link to your website, services page or Google Maps location.
- Customer support: a WhatsApp QR so customers can message you without saving your number.
- Events and notices: text details, schedules or addresses on invitations and notice boards.
Tips for a QR code that scans every time
- Keep strong contrast: a dark QR colour on a light background works best. Avoid pale colours, and avoid a light code on a dark background, because some scanners fail on it.
- Use a simple, bold logo and do not make it too large. Always scan the final code before using it.
- Print the QR at least about 2 cm wide, and leave a blank margin around it.
- Test it with more than one phone and more than one app.
Frequently asked questions (FAQ)
Does the QR code expire?
No. The code simply contains your information, so it keeps working. If you change your link or number, you will need to make a new QR.
Can I make a QR for Wi-Fi or a contact card?
This tool supports link, UPI, WhatsApp and text. For other types, enter the required text in the Text tab, but standard apps may not recognise it as a Wi-Fi or contact code.
My QR code will not scan. What should I check?
Make sure the colours have high contrast, the logo is not too big, the text is not too long, and the printed size is large enough.
Can anyone read the information inside?
Yes. Anyone who scans the code can see what it contains, so never put passwords or private information in it.
Is it free for commercial use?
The tool is free to use. Make sure that any logo you add belongs to you or that you have permission to use it.
