What is error correction level?

Error correction allows a QR code to be scanned even when partially damaged or obscured. Level L recovers 7%, M 15%, Q 25%, and H 30% of the data.

Can I use a custom foreground and background color?

Yes. Use the foreground and background color pickers. Ensure there is strong contrast between them for reliable scanning.

Frequently Asked Questions

What content types can a QR code hold? +

URLs, plain text, email addresses, phone numbers, and Wi-Fi credentials. Select the type from the dropdown and the tool formats the data correctly for each.

What is the error correction level? +

It controls how much of the QR code can be damaged and still scan. L = 7%, M = 15%, Q = 25%, H = 30% data recovery. Use H for codes that will be printed on physical materials.

What size should I choose for printed materials? +

Use 512×512 or 1024×1024 px for print. Larger sizes produce sharper results when printed on flyers, business cards, or posters.

Can I use custom colors? +

Yes. Use the foreground and background color pickers to match your brand. Ensure strong contrast between them — low contrast QR codes may fail to scan.

Is my data sent to a server? +

No. QR codes are generated entirely in your browser using the QRCode.js library. No data, URL, or password is ever sent to any server.
