Instagram introduced a huge change today, launching a fully-functional web app that lets you upload photos from a phone browser, no app needed. Instagram didn't officially add the option to desktop browsers, but it's there -- you just have to find it.
Many Instagrammers -- myself included -- shoot photos on a dSLR camera and edit them on their computer before uploading to Instagram. That means having to transfer the finished photo to a phone (via AirDrop or email), which is cumbersome, at best.
This workaround cuts that step out, making dSLR uploads easier than ever.
How to upload photos to Instagram from a desktop browser
Most browsers have a way of letting you change the "User Agent" -- the thing that tells a website what kind of device you're on. So, even when you're on a laptop or desktop, you can trick a website like Instagram into showing you the mobile site. That's what we're going to do.
On Safari, it's easy. Go to Safari > Preferences > Advanced. Check the box at the very bottom that says, "Show Develop menu in menu bar."
Now open a private browsing window. Head to Develop > User Agent > Safari -- iOS 10 -- iPhone. Go to Instagram.com, sign in and click the camera button at the bottom of the screen to upload a photo from your desktop.
In Chrome, open an Incognito window and go to View > Developer > Developer Tools. A sidebar will pop up with a bunch of scary code -- just ignore it. At the top of that sidebar, to the left of Elements, find the icon that looks like a tablet and phone. Click it.
Now go to Instagram.com, sign in and click the camera button at the bottom of the screen to upload a photo from your desktop.
