How to use it

- Fill in the details. The preview updates as you type.
- Optionally pick a colour, add a line of text under the code or your logo, and choose the PNG size.
- Tap “Download PNG” (or “Download SVG” for printing), then test-scan it with your phone before you print or share it.

UPI payment QR codes
Enter your UPI ID and name, and optionally an amount and a note. The code holds a standard UPI payment link, so any UPI app can read it, and the money goes straight to the bank account linked to your UPI ID. Leave the amount empty if customers pay different amounts. For a fixed fee — say a monthly tuition fee — fill it in so nobody types the wrong number. There are more tips on the UPI QR code generator page.
Tips for a QR code that always scans
- Keep it dark on light. Black or another dark colour on white works best. Light colours such as yellow or sky blue often fail.
- Keep the white border. Scanners need the empty margin around the code to find it — don’t crop it off.
- Print it big enough. At least 2–3 cm wide for a visiting card, and bigger if people will scan from a distance, like a poster on a wall.
- Keep the content short. A short link makes a simpler code that scans faster, even from a cracked or dim phone camera.
- Logos are optional. When you add one, the code automatically uses the highest error correction so it can still be read. Keep the logo simple.
- Always test-scan with two different phones before printing hundreds of copies.
PNG or SVG?
PNG is an ordinary image — use it for WhatsApp, documents and normal prints. Medium (1024 px) is plenty for an A4 sheet. SVG is a vector file that stays sharp at any size, so printers prefer it for banners, standees and flex boards. Need a printable page? Turn the PNG into a PDF with JPG to PDF, or shrink it for an upload form with Compress Image.
