About

Creates wa.me links to open WhatsApp chats without saving the contact. Useful for websites, signatures and promotion.

How to generate a WhatsApp link

The UtilNexo WhatsApp link generator turns a phone number into a clickable link (wa.me) that opens a chat directly in WhatsApp. It is ideal for contact buttons on websites, social media, and printed materials.

The link follows the official WhatsApp format: https://wa.me/ followed by the number in international format, without spaces, parentheses, or signs. The tool automatically removes formatting and adjusts the country code.

You can include a pre-filled message that the customer will see when opening the chat. Just type the desired text and the tool encodes it all into the link.

The generated link can be copied and pasted anywhere: website buttons, social media bios, email signatures, or even a QR Code. All processing is local and instant.

Examples

  • Number (11) 91234-5678 → https://wa.me/5511912345678.
  • With message "Hi, I have a question" → the link opens the chat with that text already filled in.

Limitations

  • The number must be in international format (country code + area code + number), without extra zeros or special characters.
  • The link only works if the number has an active WhatsApp account; the tool does not verify whether the number is valid.

How to use the WhatsApp link generator

  1. 1Type the phone number.
  2. 2Add an optional message.
  3. 3Copy the generated link and use it anywhere.
