よくある質問
Is the QR created on a server?
No. A client-side library draws the code on a canvas in this tab.
What barcode format is used?
CODE128, which accepts letters, numbers, and most URL characters.
Can I scan it from the screen?
Yes. Use a phone camera on the on-screen code, or download the PNG first.
Do you store the text I type?
No. There is no account and no log of QR contents on UtilityAll servers.
