Medium works well for everyday use. Higher correction adds redundancy but makes the code denser.
Turn text, a website address, contact details or Wi-Fi credentials into a QR code. HedgieTools generates the image directly in your browser, without uploading your content or logo. Your code contains the information you enter, not a HedgieTools tracking link.
Choose Text, URL, Contact or Wi-Fi and complete the fields. The preview updates as you type. Contact codes use vCard 3.0 so compatible scanners can offer to save the details. Wi-Fi codes let supported devices join a network; anyone who has the image can also read the encoded credentials.
Choose PNG for a raster image at your selected pixel size, or SVG for scalable artwork suitable for layouts and print. Both exports use the same artwork as the preview, including colors, logo and a white quiet zone four modules wide. Keep this margin intact when placing the image.
Use dark modules on a light background and leave enough room for the complete code. Longer content and higher error correction produce denser codes. Adding a logo automatically enables High correction and limits its size, but cannot guarantee readability. Test the final exported image on several devices and at its intended print size. These are static QR codes: changing their content requires generating a new image. Website codes continue to depend on the destination remaining available.
