What is a QR code generator?

A free QR code generator that stays out of your way.

A QR code generator turns a piece of information, such as a web address, a WiFi login or a contact card, into a square pattern that a phone camera can read. Kuadro builds that pattern in your browser, so you can try a design, scan it from the screen and download it without creating an account.

Static codes hold the content inside the image, which makes them free and permanent but impossible to change after printing. Dynamic codes hold a short link instead, which lets you change the destination later, route people by device, run A/B tests and see scans by day, device and referrer. Dynamic codes are part of the paid plans, so you can start with the free editor and upgrade when you need them.

Whatever you choose, the scannability meter checks your design before you print it. It decodes the preview and warns you when a colour, a logo or a shape makes the code harder to read. Pick a content type above to open a generator with its own guide, steps and answers.

Frequently asked questions

What people usually ask before starting.

Yes. The editor, the scannability meter and downloads in PNG, JPG, WEBP and SVG are free, and you can create static codes without an account. Dynamic codes, analytics, landing pages, custom domains, teams and the API belong to the paid plans.

A static code stores the content inside the code itself. A dynamic one stores a short link that redirects, so you can change the destination later and count scans.

Yes, with dynamic QR codes. You can also route by device or country, and split visits between variants for A/B tests.

Yes. Every dynamic QR code supports an expiry date and an optional password; after the date, the link stops redirecting.

Static codes never expire, because the content lives inside the image. A dynamic code keeps redirecting until the expiry date you set, if you set one. If a plan ends, existing dynamic codes keep redirecting, but you can no longer create new ones.

Yes. Add your domain and verify it with a TXT record in your DNS; then pick it on each code.

The editor recalculates a scannability meter with every change of colour, logo or text, and warns you before you download.

There are 23 content types: website URL, plain text, email, phone, SMS, WiFi, vCard and MeCard contacts, WhatsApp, Telegram, FaceTime, Instagram, TikTok, X, GitHub, LinkedIn, location, calendar event, UPI, Pix, PayPal, Bitcoin and Ethereum. Each one has its own generator page.

Yes. The barcode generator supports Code 128, Code 39, EAN-13, EAN-8, UPC-A, ITF, ITF-14 and Data Matrix, checks the value against each format and downloads as SVG, PNG, JPG or WEBP.

Yes. You can create API keys, review the request log and set up webhooks to receive events.
