Create a QR code people can scan
Choose the right content type
Select Website URL for an HTTPS address, Plain text for a message, Email for an address, or Phone number for a calling link. Wi-Fi codes need the network name, security type and password when the network is protected. Check these details carefully before generating the code. A QR code stores the exact content you enter; it does not automatically fix a misspelled address or provide access to a private network.
Keep the code easy to read
Use a dark foreground on a light background. The generator checks contrast and includes the blank quiet margin that scanners need around the code. Standard error correction is suitable for many uses. Stronger correction can help with modest damage but also makes a dense code larger. Very long messages create more complex patterns. For printed cards, a shorter website address is often easier to scan than a large block of text.
Export the appropriate format
Generate the preview, then choose PNG for a ready-to-share image or SVG for a scalable graphic. A larger PNG is useful for printing or placing in another design. SVG stays crisp when resized, but some messaging apps accept images more readily. Keep the quiet margin when cropping or laying out a poster. Do not place decorations over the code. Test the downloaded file with another phone, including at the size and distance your audience will use.
Know what happens after scanning
The QR code has no added tracking, shortener or expiry. A website code continues to point to the same address, but the destination must remain available. A Wi-Fi code exposes the credentials it contains to anyone who can scan it, so share it only with people allowed to use that network. Generation runs in your browser and does not upload the content to a QR service. If you change a website address or password, generate a new code and replace older printed or shared copies.
