By Alva Chew 2 min read Updated November 11, 2026

Format WhatsApp messages without remembering the symbols. Type or paste your message, select the words you want to style, and press a button. You see how it will look in WhatsApp, then copy it. Free, no sign-up.

How it looks in WhatsApp

WhatsApp formatting symbols

  • Bold: put an asterisk on each side, *like this*.
  • Italic: put an underscore on each side, _like this_.
  • Strikethrough: put a tilde on each side, ~like this~.
  • Monospace: put three backticks on each side, “`like this“`.

The symbols have to touch the words, with no space in between. You can combine them, for example *_bold italic_*.

Formatting that helps customers

  • Bold the one thing the customer must notice, such as an order number, a price or a deadline.
  • Use monospace for codes customers copy, such as discount codes and tracking numbers.
  • Strike through an old price to show a discount.
  • Keep it light. A message with every second word in bold is harder to read.

Sending the same messages over and over?

If you keep formatting the same order updates, delivery times and discount codes, AeroChat can send them for you. It answers your customers on WhatsApp and your other channels, pulls the order number and tracking from your store, and replies in the customer’s own language.
