QR Code and Barcode Tools: Create, Scan and Print Codes for Free
QR codes are everywhere now — on shop counters for UPI payments, on restaurant tables for menus, on posters, packaging and wedding cards. Barcodes do the same job for products and billing. With ToolNest you can create both, and even scan QR codes, without installing any app and without paying for a "premium" code that expires.
Create a QR code in seconds
Open the QR Code Generator, paste any link or text — your shop's UPI ID, a WhatsApp number, your Instagram profile, a Google Maps location or plain text — choose a size and download the QR as a clean PNG image. Print it, stick it on your counter or share it on WhatsApp. The code is a standard QR, so every phone camera and payment app can read it, and it never expires. The QR Code was invented by DENSO WAVE, whose official QR Code website explains how it works; UPI payments in India run on the NPCI network.
Scan a QR code without an app
Got a QR image saved in your gallery or received on WhatsApp, but your camera is not reading it? The QR Code Scanner reads QR codes from an uploaded image or your camera, right in the browser, and shows you the link or text hidden inside — useful for checking a payment QR before you scan and pay.
Barcodes for shops and stock
The Barcode Generator creates standard barcodes (Code 128, EAN and other common formats) from any number or product code. Small shops use it for billing labels, schools and offices use it for books, files and inventory — generate, download and print on normal paper or sticker sheets.
Common questions
Do QR codes made here expire? No. These are static QR codes — the information sits inside the code itself, so it works forever, free.
Is it safe to create a UPI QR here? Yes. The code is generated in your browser; your UPI ID is never uploaded or stored anywhere.
Can I scan a QR from a screenshot? Yes — that is exactly what the QR Code Scanner is for.
