Check both the code and its destination before distribution
A code without an expiry date can still point to a deleted page. Scan the saved image with another device and inspect its domain, path and readability at the actual print size. Wi-Fi passwords are not autosaved, but a generated Wi-Fi QR image contains the connection information.
About this tool
- The QR code itself has no expiration date.
- Your content is encoded directly in the QR code without going through Rakuruno.
- If a linked page is removed or its address changes, the QR code will no longer open that destination.
- Generation and autosave happen in your browser. Your input is not sent to an external server.
QR code generation uses qrcode-generator under the MIT License.
Frequently asked questions
Do the QR codes expire?
No. The QR code itself does not expire. If it contains a URL, however, it may stop working if the linked page is removed or its address changes.
Is my input sent to a server?
No. The QR code, preview, and downloaded image are all created locally in your browser.
Is my Wi-Fi password safe?
Your Wi-Fi password is not sent to a server and is not saved in localStorage or any other browser storage. The password field is cleared when you reload the page. Only non-password data, such as the SSID and settings, is saved for 30 days from the last save. The QR code image itself contains the connection details, so share it carefully.
What should I do if the QR code will not scan?
Use a quiet zone of at least four modules, turn off inversion, and save a larger image. Shortening long content can also make the pattern easier to scan.
What is the difference between PNG and SVG?
PNG works well in most apps. SVG stays sharp when enlarged, which makes it useful for print and large displays.
