1. Send your location to a contact
WhatsApp allows you to send photos and videos to contacts, as well as share a contact or document but you can also send your location. This is very handy if you're meeting a friend somewhere, especially if you opt for Share Live Location, which allows your contact to see your Live Location for the duration you choose so they can track you. Duration times are set at 15 minutes, 1 hour or 8 hours.

iOS: Chat > Specific chat > Tap on "+" to the left of the message box > Location > Share Live Location > Select time frame.

Android: Chat > Specific chat > Tap on the paperclip to the right of the message box > Location > Share Live Location > Select time frame.

2. Reply to a group message privately
It's possible to reply to a group message privately in your one-to-one chat, without having to find the one-to-one chat you have with that particular person.

iOS: Press and hold a message in a group chat > Select More > Reply Privately. The message will appear in your one-to-one chat with the text box below, as it does if you reply to a specific message like above.

Android: Press and hold a message in a group chat > Select the three buttons in the top right corner > Reply Privately. The message will appear in your one-to-one chat with the text box below, as it does if you reply to a specific message like above.

3. Turn words bold, italic or strikethrough
Sometimes certain words need more emphasis and shouty caps just don't cut it. Don't worry, WhatsApp allows you to make whichever words or phrases you want bold, italic, or strikethrough them altogether.

iOS & Android: Add an asterisk either side of the word or phrase for *bold*. Add an underscore either side of the word or phrase for _italic_. Add a tildes to either side of the word or phase for ~strikethrough~.

4.Archive your chats
Archive Chat allows you to hide a conversation from your Chats screen. It does not delete the chat - it just allows you to remove it from your main chat screen without losing it, helping you organise your conversations.

You can archive groups or individual chats, and they will disappear until you pull down from the top of the Chats display and tap the Archived Chats tab. You can also archive all chats.

iOS: Chats > Specific chat > Swipe right to left > Archive / Settings > Chats > Archive All Chats.

Android: Chats > Long press on chat > Press the archive folder at top right of the screen

5. Sending a group message without making a group chat
The message will be delivered to every receiver you have chosen. Plus, all the necessary contacts will get the message in the usual way. Their answers will be seen only by you and not the other contacts on the list.
iOS & Android: go to Chats > Menu > New broadcast. Press "+" or enter the names of receivers.

6.Bubble messages
