Before using a QR code on a website, in a layout, or on printed materials, test it with a smartphone.
Make sure the code scans successfully and opens the correct action: a link, contact, Wi‑Fi network, message, call, social profile, or payment details.
For print, use a large enough QR code and leave clear space around it.
Avoid placing the code too close to the edge of a design, cropping it, or putting it on a busy background.
The stronger the contrast between the code and the background, the more reliably cameras can read it.
If you change colors, add a frame, adjust the shape, or include a sticker or logo, test the final downloaded version.
The design must not interfere with scanning. This is especially important for business cards, menus, labels, packaging, flyers, posters, badges, and promotional materials.
For digital use, PNG, WebP, JPEG, or JPG are practical choices.
If the QR code needs to scale without quality loss, SVG is usually the better option.
For physical materials, you can also open the print version and check how the code will look on paper.
