The photo sharing platform - which is owned by Facebook - will now allow users to access their DMs from the site, rather than only getting them through the app.
However, the roll out is just a test on a "small percentage" of Instagram's global users, with more details on a possible full launch coming in the future.
As reported by The Verge, the DM service will basically be the same as it is on the mobile version.
User will be able to create new groups or start a chat with someone - either from a profile page or the DM screen - while you can also share photos from the desktop, double-tap to like a message, and see the number of unread messages you have.
Furthermore, you can also get desktop DM notifications if you enable them for the whole website in your browser.
The publication added that when asked why the company was prioritising web DMs over other things - such as an iPad app - a company spokesperson said the new update will help users "stay in touch with the people you care about".
