Static QR codes (the kind these generators produce) never expire — they encode the destination directly. Dynamic QR codes from third-party services can expire when the service shuts down or you stop paying. For business cards and flyers, static codes are safer.

What size should I print a QR code?

A good rule of thumb is the code should be at least 1/10th of the scanning distance. For a poster scanned from 2 metres, print at 20cm. For a business card scanned from 30cm, 3cm square is enough. Always print at 300 DPI to keep edges crisp.

Will the QR code still scan if I add a logo?

Usually yes. Our generators use high error-correction (level H), which lets you cover up to 30% of the code with a logo and still scan reliably. Always test with two different phones before printing a thousand copies.

Can I track how many people scanned my QR code?

Not with a static QR code — it goes straight to the destination. If you need scan analytics, encode a short URL you control (e.g. yoursite.com/promo) and track visits with your own analytics. We don't offer hosted tracking.

What's the difference between UPI and BHIM QR?

UPI is the underlying Indian payment standard; BHIM is the government's official UPI app. A QR code generated for either format works with every UPI-compatible app — Google Pay, PhonePe, Paytm, BHIM — because they all read the same upi:// URI.

Can I generate a WiFi QR code for guests?

Yes — use the WiFi QR generator, enter the network name (SSID), password and encryption type (WPA/WPA2 is standard). Guests scan the code with their camera and tap to join. Works on iOS 11+ and Android 10+.

Tools hub

All Qr Tools

QR codes for every job — URL, WiFi, UPI, vCard, WhatsApp, payments and more.

30 free tools · no signup · no watermark · runs in your browser

QR codes are the fastest way to bridge print and digital — a printed code on a flyer, business card or restaurant menu opens a website, joins a WiFi network, dials a number or launches a WhatsApp chat in two taps. The QR Tools hub has a dedicated generator for every common payload type, so you don't have to remember the right URI scheme (mecard:, WIFI:, upi://, mailto:) — pick the right tool, fill in the fields, and download a high-resolution PNG.

All QR generation happens in your browser. The library encodes the payload, applies error-correction (so the code still scans even if part of it is smudged or printed badly), and renders a PNG at any size you choose. There's no watermark, no expiry, no tracking redirect, and no account required. The PNGs are vector-sharp at any print resolution.

For static information like a WiFi password, a business card or a payment UPI ID, a self-hosted QR code is the right answer — it works forever, doesn't depend on anyone else's service, and doesn't leak scan analytics to a third party. Use a dynamic / tracked QR service only when you genuinely need to swap the destination after printing.
