Tips that scan
- Dark dots on a light background.
- Use error correction Q or H if you will print it small or cover a corner with a logo.
- Download SVG for posters; PNG for WhatsApp and print-at-home.
Wi-Fi codes use the standard WIFI:T:WPA;S:name;P:pass;; format. Need a short link on a poster? Generate the code, then compress the PNG with the image compressor.
