What is error correction level?

Error correction allows a QR code to be scanned even if part of it is damaged or obscured. Level L allows 7% of the code to be restored, M allows 15%, Q allows 25%, and H allows 30%. Use H if you plan to add a logo overlay; use L for the most compact code.

What is the maximum amount of text I can encode?

A QR code can hold up to about 4,296 alphanumeric characters or 2,953 bytes. In practice, shorter inputs produce simpler codes that scan faster and more reliably. For URLs, keep them as short as possible.

Should I download PNG or SVG?

Use PNG when you need a fixed-resolution image for printing or sharing. Use SVG when you need the QR code to scale perfectly at any size — for example, on posters, business cards, or web pages.

Is the generated QR code stored anywhere?

No. The QR code is generated entirely in your browser using the qrcode library. No text or image data is sent to any server.

Error correction levels

QR codes have four error correction levels: L (7%), M (15%), Q (25%), H (30%). Higher levels allow the QR code to be scanned even if part of it is obscured or damaged — but produce a denser image.

Frequently Asked Questions

What can I encode in a QR code?: Any text: URLs, plain text, email addresses (mailto:), phone numbers (tel:), SMS (smsto:), Wi-Fi credentials, or vCards.
What error correction level should I use?: M (15%) is a good default. Use H (30%) if you plan to print the QR code in conditions where it might get dirty or partially covered.
