Technical details
- It builds an official wa.me link with the number and, if you add one, the encoded message.
- Enter the number with its country code. Spaces, dashes and the + sign are removed, but leading zeros aren't: use +44 7700 900123 or 447700900123, not 0044 7700 900123.
- The message appears typed in the chat, but the person decides whether to send it.
- Download as PNG (128 to 1024 px) or SVG, which scales without losing sharpness for print. The code is static: it doesn't expire, doesn't go through any server and doesn't track scans.
