QR Code Generator
Make a QR code for a link, WhatsApp chat, UPI payment, Wi-Fi network, email or phone — then download it as a crisp PNG or SVG.
Scan with your phone camera to test before printing.
Private by design — everything is processed on your device. Nothing you type or upload is sent to our servers.
What it does and why it matters
A QR code lets anyone open a link, start a WhatsApp chat, pay you by UPI or join your Wi-Fi just by pointing a phone camera at it. Businesses use them on menus, flyers, packaging, shop counters, event standees, business cards and social posts.
This generator runs entirely in your browser, so the content you encode never leaves your device. The codes it makes are static, which means they never expire and keep working forever. For printing, download the SVG for perfectly sharp edges at any size, or a large PNG for quick sharing.

Are these QR codes free to use commercially?
Yes. The codes are free for personal and commercial use, and they do not expire because they are static.
Do the QR codes expire?
No. Static QR codes encode the content directly, so they keep working as long as the destination (such as your website) exists.
Is my data uploaded anywhere?
No. The QR code is generated in your browser and nothing is sent to Klaslead's servers.
Which format is best for printing?
Use SVG for print because it stays perfectly sharp at any size. Keep strong contrast — dark code on a light background — and leave a quiet margin around it.
Can I make a UPI payment QR code?
Yes. Choose UPI, enter the UPI ID, payee name and an optional amount and note. Any UPI app can scan it.
