You can even DM a friend, and upload an Instagram story using your computer. All you need is chrome.
1. Sign into Instagram and go to your profile page.
Using your PC or Mac, sign into Instagram as you normally would. Then navigate from your feed to your profile.
2. Open Chrome Developer Tools.
Right-click and select “Inspect.”
Step 3: Click the “Devices” icon.
Click the small tools icon, which is the 2nd icon from the left in the developer’s panel.
4. Select a phone model.
Once you open the developer tools, use the selection options in the top bar to select a phone model. If you’ve never done this before, your default setting will probably be set to “responsive.”
Choose a phone model.
5. Refresh Screen and you’re ready to post!
Now that you’ve setup your browser to mimic a device, you’re almost ready to post.
Hit the “refresh” button on your browser.
