QR codes that update as you type

Enter what scanners should open—often a full https:// link. Adjust size, colors, and error correction; the preview follows. Download PNG or SVG, or Copy image. Built in your browser; no signup.

QR code controls and preview

Menus, Wi‑Fi cards, and event links—export, then test with a real phone.

1 Link or text · 2 Size & correction · 3 Colors & optional logo · 4 Download, copy, or scan-test

Your QR

Use a full https:// URL when you can. L fits longer payloads; H helps worn or outdoor prints. If the text is too long for your level, we lower correction until it fits. A center logo appears on PNG and Copy image; SVG is modules only.

Quick size

Encoder runs in this tab. Your characters are not sent to us to draw the pattern.

After the encoder loads, changes in Link or text update the preview. Generate QR code redraws and scrolls to the result on small screens.

  • QR is drawn in your browser—not sent to our servers to encode
  • Scan with a real phone before a big print run
  • Optional logo on PNG and copy; SVG stays a plain vector grid

When this helps

You need a square people can scan—menus, flyers, Wi‑Fi cards, or short links on paper.

  • URLs, plain text, mailto:, tel:, or WIFI: strings
  • Higher error correction for outdoor or rough handling
  • A small logo on PNG or copied image; SVG without the badge

If a phone will not read it, shorten the text or try a lower correction level.

Keep it scannable

Type the exact string a camera should read. Watch the live preview while you change size and correction—we step correction down when the payload is long. Then grab PNG, SVG, or Copy image and test on a phone.

How it works

  1. Enter text in Link or text; the preview updates as you type (or press Enter for Generate QR code).
  2. Pick Size (128–520 px) or a quick preset and Error correction (we may use a lower level if the data does not fit).
  3. When controls appear, set QR color, Background, or Transparent; optional Add logo / Remove logo (logo on PNG and Copy image only, not SVG).
  4. Use Download PNG, Download SVG, or Copy image; Generate QR code redraws and scrolls on narrow screens.

Privacy: The QR is drawn on your device. Other scripts on the page (for example analytics) may load separately; the encoder itself does not send your payload to us to build the code.

FAQ

  • Do you see my URL? No. Encoding runs in your tab.
  • Error correction? Higher levels survive damage but fit less text. We lower the level automatically when needed.
  • Commercial use? The file is yours; respect trademark rules if you add a logo.
  • Why no code? The string may be too long—shorten it or pick a lower correction level.
  • Mobile? Yes—the layout stacks and the preview stays reachable.
