Add to ZIP option in context menu for WinRAR

there is a option, you can set by going in setting.. Go to Options-> Settings-> Compression -> (Compression Profiles)Create Default-> Archive Format-> Select Zip-> Click Ok-> Again Ok----> You Are Done :)

There is also another way to use an existing profile or create a new profile and add that new profile to the context menu without setting or changing your default profile:

1) Right-click on the file you would like to ZIP. 2) Click 'Add to archive...' from the Context Menu.

If you already have a profile set that you would like to use, such as 'Add to ZIP', then all you have to do is:

4) Click the 'Profiles...' button. 5) Left-click the profile you want to add to the context menu to highlight it. 6) Click the 'Edit' button to the right. 7) Use the existing name or change it if you want. 8) If you want the context menu item to execute immediately, then check 'Immediate Execution' or leave it unchecked if you want it to pop-up the options box before processing. 9) Check 'Add to context menu' to add that profile directly to the context menu for future use.

If you don't have a profile already set for ZIP files, then:

4) Set all of the settings you want in the options dialogue to process these types of files when executed from the context menu. 5) In the General tab, click 'Profiles...' and select 'Save current settings to a new profile...' 6) Change the 'Profile name' to something more descriptive to let you know what it does. (e.g. 'Add to ZIP') 7) If you want the context menu item to execute immediately, then check 'Immediate Execution' or leave it unchecked if you want it to pop-up the options box before processing. 8) Check 'Add to context menu' to add that profile directly to the context menu for future use.
