QR code generator
Turn links and text into QR
Your QR code will appear here once you enter something.
What you enter is turned into a QR code on this device only. It's never sent to a server or saved.
How to use
- Under Content type, choose Text / URL, Wi-Fi, or Contact.
- Enter the content and the QR code appears in the preview right away.
- Adjust size, margin, error correction, and colors under Settings if you need to.
- Save it with Download PNG or Download SVG, or use Copy image to paste it somewhere.
FAQ
Do these QR codes expire?
No. The content is stored in the QR code itself, with no redirect server or short link in between, so it keeps working as long as the content is valid. The flip side is that you can’t edit it after printing. If the link may change, you’ll need to make a new code.
How do I make a Wi-Fi QR code?
Choose Wi-Fi, then enter the network name (SSID), password, and security type. Guests can scan it with their phone camera to join without typing the password. The name and password must match your router exactly, including capitalization. The password isn’t saved.
It says there’s too much to fit in a QR code.
A QR code can only hold so much data, and higher error correction leaves less room. Lower the error correction or shorten the content. For long text, put it on a web page and make a QR code for the link.
Which error correction level should I use?
The default, Medium (15%), works well for screens and normal printing. Pick High or above for stickers that may get scratched, or if you plan to place a logo over the code. Higher levels survive more damage but make the pattern denser.
PNG or SVG?
PNG is an image at the size you choose (200 to 1024 px), handy for documents and chats. SVG stays sharp at any size, which suits posters and design work. Files are saved as kitvoo-qr.png and kitvoo-qr.svg.
Why do I see a warning after changing colors?
The warning appears when the two colors are too close, or when the QR color is lighter than the background. Some scanner apps can’t read those combinations. A dark code on a light background scans most reliably.
Copy image doesn’t work.
Some browsers or permission settings block copying images to the clipboard. If the button shows “Copy failed”, use Download PNG and paste the file instead.
