Codice QR
Testo, URL, Wi-Fi
Customize
Tip: when adding a logo, keep error correction at "H" so the code stays scannable. Always test with a real phone before printing.

Informazioni su questo strumento
Generate a QR code for any URL, contact card, Wi-Fi credentials, email link, SMS, or arbitrary text - entirely in your browser. Download as PNG or SVG and print, embed in a slide deck, paste into a flyer, or stick on a poster. Nothing is uploaded, nothing is logged, and there's no third-party tracking shortcut baked into the URL.
QR codes are static once printed: they don't expire and don't phone home, but they also can't be edited after the fact. If you need to change where the code points later, link to a URL on a domain you control and update the destination behind that URL rather than the QR itself. For one-off codes like a Wi-Fi password sticker or an event entry, that's overkill - just generate, print, and move on.
Error correction is built into the QR specification: a code with 30% error correction is still readable when nearly a third of the surface is damaged or obscured. The trade-off is that higher correction means a denser pattern. The default in this tool (medium, around 15%) is the right balance for screen and clean print; bump it to high if the code will be printed small or on a surface that might get scratched.
Funzionalità
- URL, text, Wi-Fi, vCard, email and SMS payloads
- PNG and SVG export (SVG scales to any size without blur)
- Adjustable size up to 2048 pixels
- Four error correction levels (L, M, Q, H)
- Custom foreground and background colors
- Runs entirely in your browser - nothing is logged
Come si usa
- Pick the QR type from the tabs (URL, text, Wi-Fi, etc.).
- Fill in the content - the preview updates as you type.
- Adjust the size, error correction level and colors if needed.
- Download as PNG (for printing or pasting) or SVG (for scaling cleanly to any size).
Tutto avviene all'interno del tuo browser con JavaScript e WebAssembly. I tuoi file non vengono mai caricati su un server, mai memorizzati e mai visti da noi.
Domande frequenti
No. They're static images and work forever, as long as the URL or text inside them is still valid. If you point a QR at a URL that later goes offline, the code itself is still readable - it just leads nowhere.
Yes. Modern iOS and Android cameras decode QR natively - no app needed. Point the camera and tap the notification that appears.
SVG scales to any size without blur or pixelation, which matters when you're printing a code at poster size or embedding it in a layout tool. PNG is the right pick if you need an image to drop straight into chat or email.
Not in this tool. QR codes can tolerate a small center overlay thanks to error correction, but doing it safely requires manual layout in a design tool. Generate the QR here with high error correction, then overlay your logo in something like Figma or Affinity Designer.
