How to Post to Instagram on a Desktop
You can access Instagram on your PC or Mac using a web browser to review your feed, like and comment on posts, view your profile, and follow or unfollow people. Instagram also recently added the ability to send and receive direct messages. You can also post photos or videos.
Use the Instagram for Windows Desktop App
The Instagram for Windows desktop app works the same as the web version. You can post photos or videos, view posts, like and comment, and follow and unfollow users. Instagram for Windows doesn’t work with older PCs or Macs, though.
Workarounds for Older Computers
If you want to post photos and videos to Instagram from your desktop and you have a Mac or older PC that can’t run the Instagram for Windows app, there are some workarounds.
BlueStacks
BlueStacks is a free Android phone emulator. It emulates the Android version of Instagram on a PC or Mac, making it possible to upload photos to Instagram. Install BlueStacks, then download Instagram. Sign in to your Instagram account, and your Instagram feed appears as it does on a phone.
Flume
Flume is a Mac-only Instagram app that allows you to upload photos, post to Instagram from a Mac, edit photos, and more. It also includes some power-user functions the mobile Instagram app doesn’t offer, such as hover shortcuts and ways to promote your brand.
If there’s a photo on your desktop computer you want to post on Instagram, a low-tech solution is to email yourself the picture, access that picture from your phone, then post it to Instagram.
Dropbox
Use Dropbox, the free cloud-based storage app, to share photos on your desktop computer to your mobile device, then access those photos in Instagram.
Pixlr
Pixlr isn’t a desktop Instagram workaround. Instead, it’s a photo app with features similar to Instagram. Pixlr calls itself a “next-generation online photo editor.”
