QR Code Generator

Yes, it is completely free with no sign-up, watermarks or scan limits. The codes it makes are static QR codes, which means the data (a link, text, Wi-Fi details, etc.) is encoded directly into the pattern. Because nothing is stored on a server, they never expire and work forever — the only way one stops working is if the link it points to goes offline or the printed image is damaged.

Yes. You can change the foreground and background colors, pick a module and corner style, and drop a logo into the center for branded codes. Keep the logo to roughly 20% of the code or smaller, use a high error-correction level so it stays scannable, and stick to dark patterns on a light background — light-on-dark codes can fail on older scanners.

For screens, any size works; for print, generate at high resolution (or use SVG) and aim for at least about 2 × 2 cm. Error correction has four levels — L (7%), M (15%), Q (25%) and H (30%) — that set how much damage a code can survive. Use M for clean digital use, Q for packaging and outdoor signs, and H whenever you add a logo, since the logo covers part of the code.

Yes to both. The QR code is generated entirely in your browser with JavaScript — your link, Wi-Fi password, contact card or any other text is never sent to a server or uploaded anywhere. Once the page has loaded you can even disconnect from the internet and keep generating codes.

Use SVG when you plan to print — it is a vector format that scales to any size, from a business card to a billboard, with no blur or pixelation. Use PNG for digital uses like websites, email and social media, where a fixed-size image is all you need. Both downloads contain the exact same QR code.
