QR Code Generator

1. Pick the type of QR you want along the top.
2. Fill in the fields — the code appears immediately, no button to press.
3. Adjust colours, size, border and error correction if you need to.
4. Add a centre logo if you want one, and read the warning if it appears.
5. Download the PNG for screens and everyday printing, or the SVG for large-format printing.
6. Scan the result with your own phone before you use it anywhere.

A QR code is not a link to a service; it is the data itself, encoded. A Wi-Fi QR literally contains your network name and password, and a UPI QR contains your UPI ID and the amount. That is exactly why generating them on someone else's server is a poor idea, and why this one does not.

Both downloads come from the same source data. The PNG is drawn to a canvas at whole-pixel modules so the edges stay sharp; the SVG is built from the module grid, which makes it infinitely scalable and tiny — the right choice for printing on a banner or a shop board.

Worked example

What your result means

Higher error correction makes a denser code that survives damage, dirt and a centre logo. Use H when printing on something that will be handled; M is right for a screen.

The quiet zone matters. The white border is part of the code — scanners use it to find where the code begins. Reducing it below four modules is the most common reason a printed QR stops working.

Test before you print. A code that scans on your screen can fail on paper at a different size, in poor light, or through a scratched phone camera.

• Never print a QR you have not scanned yourself, in the size and material you are actually using.
• Dark foreground on a light background. Inverted codes — light on dark — fail on many scanners.
• A UPI QR with no amount lets the customer type it. That is what you want for a counter code; fix the amount only for a specific bill.
• A Wi-Fi QR contains your actual password in readable form. Anyone who photographs the code has your password, so treat a printed one like a written one.
• For printing larger than about A4, use the SVG. It stays sharp at any size, where a PNG will not.
• Shortening a long URL first makes the code much less dense and far easier to scan from a distance.
• WhatsApp numbers need a country code. A 10-digit number is treated as Indian and +91 is added.

Limitations of this tool

• The SVG download contains the QR code only. An uploaded logo is not included, because the SVG is built from the code data rather than the rendered picture — use the PNG when you need the logo.
• Static codes only. The content is fixed at the moment you download it, so a URL cannot be changed later without printing a new code. Dynamic codes require a redirect service, which would mean a server.
• No scan tracking or analytics, for the same reason.
• Very long text produces a dense code that needs a good camera and steady light. Keep URLs short.
• Logos are placed centrally at a fixed size. There is no shaped-eye, gradient or artistic styling.
