Complete guide on how to upload pictures from your computer on Instagram
Earlier this year, Instagram announced that you could send and receive direct messages from your computer while browsing your feed. It's a welcome addition, and undoubtedly more convenient to use a full keyboard, but the social network is still missing a key feature: Officially supporting the ability to post photos from a Mac or PC.
That's all right, though, because there's an unofficial trick that makes it possible to post photos to your feed directly from your computer. The process takes a little bit of effort to get set up, but once you do it, it's pretty simple to keep going.
Note that you won't be able to use this trick to post videos. For now, it's a photo-only tip.
Most web browsers have a way of letting you change the "user-agent" -- the thing that tells a website what kind of device you're on -- to make it look like you're on a different device.
These steps can be used to post to Insta from Chrome, Firefox, and the new Microsoft Edge browser. I'm using Chrome as the example below, but the process is nearly identical for all three browsers.
Open Chrome, visit Instagram.com and sign in to your account. Right-click anywhere on the page and then select Inspect (Inspect Element in Firefox) from the list of options.
By default "inspect" tab will open at the bottom but you can change the position where you like to follow the short video under.
A window with random text will show up at the bottom of the page. The only thing we care about is the small tablet icon in the top-left corner of the Inspector tool. In Firefox, that icon is on the top-right of the inspector tool.
Click on the icon that looks like an iPad with an iPhone next to it. The Instagram interface should refresh, giving you the mobile website, complete with the + button to create a post. If you don't have the post button, refresh the page until it shows up. It may take more than one refresh.
When you're done posting your photo, click on the tablet icon again and close the Inspector tool.
Post Instagram photos from the Safari browser
Open Safari and click on Safari in the menu bar at the top of your Mac's screen. Next, click on Preferences and then select the Advanced tab.
At the bottom of the page will be a checkbox labeled Show Develop menu in the menu bar: Check it.
Next, open a new Safari window or tab and go to Instagram.com. It'll be the normal Instagram site, but that's about to change. Click on Develop in the menu bar at the top of your screen, then go to User Agent > Safari -- iOS XX -- iPhone. The "XX" part of that will change based on the current version of iOS, but the gist of the option will remain the same.
Refresh the tab or window with the Instagram site loaded, and as it reloads you'll now find a + icon at the bottom of the page. Click on the + sign to pick a photo on your Mac and then go through the steps just like you were on your phone, including selecting filters, editing, and all of that fun stuff.
When you're done, make sure you change your user-agent back to the Default setting to avoid viewing all websites in their mobile state.
Pretty easy, right? And now that you know how to quickly switch between the desktop and mobile versions of Instagram's website, you can effortlessly post photos without having to wait for edits you make on your computer to sync to your phone.
I prefer Google Chrome, so you can also use this extension from the Google store which I using.
There's also a lot of video on Youtube.
