💡 How to Use
Type a URL or any text into the input field and the QR code preview updates in real time. Adjust the size slider to set the resolution, then download as an SVG file or copy the image directly to your clipboard. Typical uses include embedding links in business cards, posters, and product packaging, or sharing Wi-Fi passwords and contact details. Download as SVG for print use — it stays crisp at any size.
