Instagram was built for phones, but you do not need one to post a photo or video. You can also do it from a computer using a browser like Chrome, Safari, or Edge. Here is how it works, based on what users report and what Instagram’s help pages say.
Post from the Instagram website
This is the simplest way to post. In fact, most users rely on it.
- Open your browser and go to instagram.com.
- Log in with the account you want to use.
- Find the “+” (Create) icon. It usually sits near the top of the page or in the left menu.
- Choose Post.
- Select a photo or video, or drag the file into the upload box. Common formats include JPG, PNG, and HEIC.
- If asked, adjust the crop or size. Then continue.
- Add filters or edits if you like. Then continue again.
- Write your caption. You may also see options for location, tags, alt text (a short description for accessibility), and turning off comments.
- Click Share to post it.
If you do not see a Create button
Some users say the “+” icon does not show up on certain browsers. So a common workaround is to make your browser show the site as if it were a phone.
- Open your browser’s developer tools. On Windows, this is usually the F12 key. On Mac, there is a similar shortcut.
- Find the device toolbar or mobile view option in the panel. Then turn it on.
- Pick a mobile device from the list.
- Refresh the page. The site should now look like the app, with a “+” button.
This is not an official Instagram feature. It is just a trick some users rely on, so it might look a little different in your browser.
“Your post could not be shared” error
Some users hit an error that says “Your post could not be shared. Please try again.” One Reddit user said the problem cleared up around April 2024 after they tried again on a Mac using Chrome and Firefox. However, that is just one person’s experience, not a confirmed fix, so it may not work the same way for you.
Other users say converting their image to JPG fixed the same error. That suggests the problem is sometimes tied to the file format instead of the site itself.
Photo quality and sizing tips from users
People who post a lot of photos from a PC share a few tips. These come from user experience, not official advice, so treat them as things worth trying.
- Turn on the “Upload at highest quality” option in Instagram’s settings, if your account has it.
- Resize images to exactly 1080 pixels wide before uploading. Height can vary, up to about 1350 pixels, according to user reports. This can help avoid the blurry look that comes from compression.
Because these are user tips and not confirmed rules, results can vary from one account to another.
Third-party desktop apps
A few tech sites mention third-party apps, such as Gramblr, as another way to post from a desktop. However, these apps ask for your Instagram login, and Instagram did not make them. So only use tools you trust, and know the risk before you type in your password.
If you also manage content on other platforms, tools built for video editing or creating thumbnails with an AI thumbnail tool can save time when you prep posts. In addition, if you post on many networks, remember that Twitter has its own history of outages, so upload issues are not unique to Instagram. Finally, if you want to limit how much Instagram tracks you, there is a separate guide on ad tracking too.
