How Can I Post on Instagram from My Mac or PC!?

The progression goes something like this: First, you don’t spend any time on Instagram at all. Then, you decide that it’s important for your business (because it is).

Earlier, we talked about eCommerce Pictures, and why you should use a DSLR for your media. Some people have achieved great success with guerilla-style, warts-and-all Instagram marketing.

But the vast majority of serious pros use a DSLR and spend some time on the images and videos they create. But what’s the best way to get that photo from an SD card to Instagram? I’ll show you how to post on Instagram from a Mac or PC.

What’s the best way to get your photos from your DSLR to Instagram?

I’ll confess. When I was first doing this, I would message myself the images and videos using Apple’s built-in Messages app. I would save the image to my phone, and then upload it to Instagram.

It works, but it’s a pain. The more you do it, the more frustrated you get with the whole thing.

I love browsing on my computer, it’s a great way to research hashtags and generally appreciate the visual art form that is exploding there. Especially for those with a retina display, high-quality photos are what Instagram was made for.

Improve Your Mac to Instagram Workflow With this Simple Hack

Both Safari and Chrome have built in options to define the “User Agent”.  Just one of many powerful developer tools always lurking under the surface of apps you use every day.

Safari Instructions

If you use the Mac’s default internet browser, Safari, you can easily find this menu at the top of your screen:

If you’re like most people, you’ve probably never clicked that “Develop” menu item in your life.

Don’t worry, I’m not going to ask you to learn coding here!

But, I will show you this simple, simple trick.

You can see that by default, the “User Agent” is automatically chosen.

The user agent is how your browser identifies you, and tells websites what kind of system you are coming from.

I’ll admit that it’s slightly scary that we’re constantly being identified by our browser, our location, our IP address… I suppose that’s just the world we live in. In fact, you’re probably not aware of all the ways you are tracked online, but that’s the subject of another post entirely…

Luckily for us, we can “trick” the system by selecting our own user agent from the menu. You can choose whatever you want, but for our purposes, we’ll select “iPhone”.


  1. Visit
  2. Click Develop -> User Agent
  3. Click iPhone

Instagram will now automatically reload the page, and it will think you are coming from a phone instead of a computer. Now you will see this little icon at the bottom center of your screen:

Just click the camera icon, and you can now upload straight from your computer! No more inconvenient solutions!

Chrome Instructions

In Chrome, the instructions are largely similar. The only difference is that you’ll want to click the menu item that looks like this:

From there, select the icon that looks like this (it’s a little tricky to find):

Use Chrome to Upload to Instagram

Once you’ve clicked that block, you can now switch the user agent in Chrome to whichever device you’d like to test — this works well for tablet testing as well!

As an added bonus, this is a great way to check your website for mobile formatting in general!

Some people check mobile formatting of their website by dragging the screen in and making it smaller, which is definitely a great way to test if your site is responsive and mobile-friendly.

If you want to take things a step further, setting the user agent to phone or tablet gives you an even more accurate representation of how your website will display on these devices, without you actually having to pull out your phone to confirm.

One Last Solution: Using “Later”

The more you dive into Instagram as a content marketing tool, the more you’ll be wanting to schedule posts. For this, I recommend Not only does Later let you upload to Instagram straight from your Mac or PC, it also lets you schedule posts throughout the week, making your workflow that much smoother!

So there you have it! With either the simple hack or by signing up for Later, you can improve your Instagram game and save yourself valuable time and effort. Now you know how to post on Instagram from a Mac.
