Features such as Chat Reactions and Chat Reply are included, and Lenses for video calls will soon be added, along with the ability to send Snaps from the computer.
An interesting feature is the privacy screen that hides the Snapchat window when it's not the frontmost task.
"With so many in our community spending more time online – whether it is for remote learning or working, streaming or just plain browsing – we saw a huge opportunity to make it easier for our community to stay connected throughout their day," the company said.
A team of Australian-based Snap engineers played a key role in developing Snapchat for Web.
Ryan Thomas, who leads the Sydney based engineering group, said: "We've got a very talented team of local engineers who build Calling for Snapchat, and have extended this onto Snapchat for Web.
"With over 100 million Snapchatters making calls to their friends on Snapchat every month, we knew this was a critical element to get right. We're pleased that an important part of the Snapchat for Web experience has been created here in Australia and will be utilised by people all over the world."
