What it does

QR Builder turns text (including URLs) into a QR code you can scan with a phone camera.

This tool is fully client-side: it does not upload your content.

How to use it

• Open: https://tedt.org/tools/qr-builder.html
• Paste or type your content.
• The QR code updates as you type.
• Press ⌘/Ctrl+Enter to force a render (helpful if you’re pasting large content).

Notes

• QR generation uses the qrcodejs library loaded from jsDelivr.
• If scanning fails, shorten the content (long strings force denser codes).

Options

• Size: Larger sizes are easier to scan at a distance.
• Error correction (ECC): Higher ECC is more tolerant, but increases density.
• Colors: For reliability, keep strong contrast (dark foreground, light background).
