Question 1

Is this free?

Accepted Answer

Yes, completely free, with no sign-up and no limit on how many QR codes you generate or scan.

Question 2

Is the content I enter sent to a server?

Accepted Answer

No. Every QR code is generated entirely on your device using JavaScript — the text, link, or contact details you enter are never uploaded anywhere.

Question 3

Do I need to install anything?

Accepted Answer

No. Every tool runs directly in your web browser using JavaScript — there's nothing to download or install.

Question 4

Is there a limit on how many QR codes I can generate or scan?

Accepted Answer

No hard limit. The batch generator caps a single run at 200 lines to keep the page responsive, but you can run it as many times as you like.

Question 5

What types of QR codes can I generate?

Accepted Answer

URLs, WiFi networks, contact cards (vCard), email, SMS, phone numbers, plain text, calendar events, GPS locations, WhatsApp chat links, and app download links.

Question 6

Do QR codes generated here expire?

Accepted Answer

No. These are "static" QR codes — the content is encoded directly into the pattern, so it works forever and doesn't rely on any server staying online.

Question 7

Does this work on mobile?

Accepted Answer

Yes — it works in any modern browser on desktop or mobile. The camera scanner uses your device's back camera automatically where available.

Question 8

How is this free?

Accepted Answer

Because all processing happens in your browser, there's no server cost per QR code. The site is supported by advertising rather than charging per use.
