Editing QR codes

After you insert a QR code, you can use the Object properties docker to customize the pixel fill, the background fill, the pixel outline, as well as the pixel shape and corner roundness. When you customize the shape of the pixels, the markers (the three larger squares in the corners, as well as one or more smaller squares in the interior of the code pattern) remain unchanged to maintain the readability of the code. You can also specify the margin around the QR code or weld the pixels together.

Error correction

Visual effects, logos, or text added to a QR code can give it an artistic look but may be considered errors by scanners. You can use the error correction settings to minimize the possibility of error when scanning the QR code. For example, if part of the pixel pattern is covered by a graphic or text, the error correction duplicates some of the hidden data so that this data can be recovered. Four levels of error correction are available. Higher correction levels duplicate a higher percentage of the information, which may limit the amount of new information a QR code can store. This may be a problem for QR codes that are approaching, or already contain, the maximum amount of information before high error correction is applied. In that case, you are prompted to reduce either the correction level or the amount of data in the QR code.

You can move, resize, scale, and align the QR code like any other object. For more information, see Working with objects.

With QR codes, you can use styles to control the appearance of the fill, outline, and other properties. For more information, see Working with styles and style sets. You can also change the default look of QR codes by modifying the default object properties. For more information, see Managing default object properties.
