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://preview.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).
