Instagram is one of those mobile-first platforms that just don't seem to care about the desktop. The app has a barebones Web view that only recently started letting people sign up for the service. Until then, people without smartphones had no way to sign up for Instagram.

Things aren't that bad anymore and you definitely can sign up on the Web, but it's still not possible to post photos from there. Even the official Instagram app for Windows doesn't let you post photos from all devices. It didn't work for us on a Windows 10 laptop, though if you have a Windows 10 convertible with a camera, your experience might be different.

If you want to avoid using third-party apps, then you could try an Android emulator such as Bluestacks. You can install Instagram for Android via the emulator and start uploading pictures and videos just as you would on a smartphone. But that's very complicated way of doing something that should be relatively simple.

Thankfully, there are third-party apps that will help you use Instagram on the desktop. This does mean that you allow a third-party app access to your Instagram account and some data and if that makes you uncomfortable, you probably will just have to wait until Instagram releases an official tool for this. If it's not an issue, here's what you need to do.

Download and install Gramblr on your PC and Mac.

Open the app and create a Gramblr account. You will need to provide your Instagram username and password during sign up.
The app will open a new tab or window in your browser and prompt you to select an image.
Now, either click the big box and choose a file to upload or drag and drop an image or video.
Click and drag on the image to crop it.
Hit the green Save button.
You can now apply filters or other effects and once done, hit the green Continue button.
Now write a caption and add your hashtags.
Below the image, you can type Instagram usernames to tag people as well.
Click Send.
