QR Code Gadget is a set of free QR tools that run entirely in your web browser. Scan a code from a restaurant menu, decode one from a screenshot, or make your own for a business card. The processing happens on your device using client-side JavaScript, so Wi-Fi passwords, contact details, and links are never sent to a server.

Built and maintained by David. I record a video tutorial for every tool on the site, and you'll find them all in the tutorials. There's more about why I built it this way on the about page.

Frequently Asked Questions

Is QR Code Gadget really free?
Yes, all tools are completely free with no hidden fees, subscriptions, or premium tiers. We support the site through non-intrusive advertising.
Do I need to create an account?
No. There is no account creation, sign-up, or login required. Just open the tool you need and start using it immediately.
Is my data safe?
Absolutely. All QR code processing happens locally in your browser. No QR code images or decoded results are sent to our servers. All processing is local.
Do these tools work offline?
Yes. Once the page has fully loaded, all tools continue to work without an internet connection. This is possible because the tools use client-side JavaScript and can be cached by your browser.
What devices are supported?
Our tools work on any modern device with a web browser, including smartphones (iPhone, Android), tablets (iPad, Android tablets), laptops, and desktop computers. The camera scanner requires a device with a camera.
Can I use QR Code Gadget for commercial purposes?
Yes. QR codes generated with our tool are yours to use for any purpose: personal, commercial, or educational. There are no watermarks, branding, or usage restrictions on generated QR codes.
Do QR codes expire?
No. QR codes are static data encoded into an image, so they do not expire. However, if you encode a URL into a QR code, that website could go offline in the future. The QR code itself will always contain the same data.
What file formats can I download QR codes in?
You can download generated QR codes as PNG (raster image, great for digital use) or SVG (vector image, ideal for printing at any size without loss of quality).
