how to create a WhatsApp link with a pre-filled message
A wa.me link with the text parameter opens the chat with the message already typed: the person only taps send. The hard part is encoding the text without mistakes. The generator below does that and shows the bubble preview.
The accented a takes 2 UTF-8 bytes (%C3%A1), the comma becomes %2C and the question mark becomes %3F.
The line break is %0A and the exclamation mark is encoded as %21 so the link survives HTML and Markdown.
The asterisks become %2A and the emoji takes 4 bytes. When opened, WhatsApp shows Promo in bold.
Opens WhatsApp so the person chooses who receives it: good for share buttons.
Build https://wa.me/ plus the number with country and area code, then ?text= and the URL-encoded message. Here you type the number and the text and the link comes out ready, with line breaks, accents and emojis already encoded. Whoever clicks opens the chat with the message written, needing only to tap send.
No. It opens the chat with the text filled in, but whoever clicked still has to tap send. No link can send a message on someone's behalf.
No. Write the text normally, with accents, emojis and line breaks, and the tool returns the encoded link along with a preview of how the bubble looks in WhatsApp.
Yes, it is an ordinary web link. On networks with a single bio link it opens WhatsApp on phones; on a computer it opens WhatsApp Web or the app. Test both before publishing.
Enter the number with its country code (or leave it blank and write only a message to create a share link that opens the contact list). The link appears here, ready to copy, test and turn into a QR code.
Links you copy or test show up here.
