Builds QR codes for URLs, WiFi, contacts and plain text, drops a logo in the middle, and downloads as PNG or SVG.

How to use it

1. Pick a type (URL, Wi-Fi, contact, message)
2. Enter the content — the preview updates as you type
3. Adjust error correction, size and colors
4. Save as PNG or SVG (use SVG for print)

Common questions

Does the QR code I make expire?

No. The content sits inside the QR itself rather than behind a shortened URL, so it keeps working for as long as the image exists.

Which error-correction level should I pick?

M is plenty for ordinary use. Choose H if you are putting a logo in the middle or printing onto something that may get damaged. The higher the level, the denser the QR.

How do I use the WiFi QR?

Enter the network name (SSID), the password and the security type. Pointing a camera at it connects without typing the password. It works with the stock iOS and Android cameras.

What is the minimum size for printing?

At least 2cm × 2cm in the real world, with a quiet margin of at least four module widths around it. The margin is added for you.

I added a logo and it says it cannot be read.

The logo is covering too many modules. Shrink it, or raise the error correction to H (30%). This tool actually re-reads the QR it made, so keep adjusting until the message turns green.
