You can post to Instagram from a computer using the web version, but the process differs slightly depending on whether you use a Mac or Windows machine

Instagram's web version lets you upload photos and videos directly from your computer to your feed, Stories, or Reels. The desktop site works in any modern browser—Chrome, Safari, Firefox, or Edge. You'll need to be logged into your Instagram account, and your image or video file must be saved on your computer already. The upload process takes about two to five minutes from start to finish, depending on file size and your internet speed.

The main limitation: Instagram's web version doesn't let you crop or filter images the way the mobile app does. You'll need to edit your photo or video on your computer first using built-in tools (like Photos on Mac or Photos app on Windows) or free software like GIMP or Canva before uploading.

Key Takeaways

  • Go to instagram.com in your web browser, log in, and click the plus icon in the top navigation to start a new post.
  • Select your image or video file from your computer—Instagram accepts JPG, PNG, GIF, and MP4 files up to 8 MB for photos and 4 GB for videos.
  • Add your caption, location, and alt text directly on the web version, then click Share to publish to your feed.
  • Stories and Reels posted from a computer appear the same as mobile posts, but you cannot add stickers, text, or filters through the web version.
  • If the plus icon doesn't appear, you may be using a restricted account type or your browser may need to be refreshed.

Step-by-step: posting a photo or video to your Instagram feed

Open your web browser and go to instagram.com. Log in with your username and password if you're not already signed in. Look for the plus icon (+) in the top navigation bar on the left side of the screen—it's usually the second icon from the left, after the home icon.

Click the plus icon. A window will open asking you to select a file from your computer. Click "Select from computer" and browse to the folder where your image or video is saved. Click the file once to select it, then click "Open." Instagram will upload the file and show you a preview.

On the preview screen, you can adjust the size or position of your image by dragging the corners. If you're posting a video, you can trim it by clicking "Trim" at the bottom. Once you're satisfied with how it looks, click "Next."

On the next screen, add a caption in the text box. You can mention other accounts by typing @ followed by their username, or add a location by clicking "Add location." Scroll down to add alt text—this describes your image for people using screen readers. When everything looks right, click "Share."

Posting to Stories from your computer

Click the plus icon and select your image or video as described above. Instead of clicking "Next," look for a button or option that says "Story" or shows a Stories icon. Click it to post to your Story instead of your feed.

Stories posted from a computer will appear in your Story for 24 hours, just like mobile posts. However, you won't be able to add text, stickers, filters, or draw on the image through the web version. If you want those features, you'll need to edit your image on your computer first using Canva, Photoshop, or another design tool, then upload the finished version.

Posting Reels from your computer

Reels are short videos, and you can post them from a computer, but the process is more limited than on mobile. Click the plus icon, select your video file, and look for a "Reels" option. Your video must be between 15 seconds and 10 minutes long and in a vertical format (taller than it is wide) for best results.

Once you upload a Reel from your computer, you cannot add music, text, or effects through the web version. If you want to add these elements, edit your video on your computer using free tools like DaVinci Resolve, CapCut, or Canva, then upload the finished Reel. Add your caption and click "Share" when you're ready.

File types and size limits Instagram accepts

Instagram accepts JPEG, PNG, and GIF files for photos. For videos, use MP4 or MOV format. Your photo file should be no larger than 8 MB, and your video should be no larger than 4 GB. If your file is too large, compress it on your computer before uploading—most operating systems have built-in compression tools, or you can use free online tools like TinyPNG or Handbrake.

Your image should be at least 1080 pixels wide for the best quality on Instagram's feed. If you're posting a Reel or Story, use a vertical video format (9:16 aspect ratio) so it fills the screen. If your video is in landscape or square format, Instagram will add black bars to the sides, which looks less polished.

Why the plus icon might not appear

If you don't see the plus icon in the top navigation, your account type may be restricted. Business and Creator accounts sometimes have different posting options than personal accounts. Try switching to a personal account in your settings, or log out and log back in to refresh your browser session.

If the icon still doesn't appear, try a different browser or clear your browser's cache and cookies. Open your browser settings, find the option to clear browsing data, select "Cookies and cached images," and click "Clear." Then go back to instagram.com and log in again. If you're using an older browser version, update it to the latest version and try again.

Editing your post after you share it

After you post, you can edit your caption, location, and alt text by clicking the three dots (⋯) in the top right corner of your post and selecting "Edit." You cannot change the image or video itself once it's posted—you'll need to delete the post and upload a new one if you want to swap out the file.

You can also turn off comments, hide your like count, or archive the post from the same menu. These changes take effect when ready and don't require you to re-post.

Frequently Asked Questions

Can I schedule a post on Instagram from my computer?

The web version does not have a built-in scheduling feature. You can post when ready, but you cannot set a date and time for the post to go live later. If you want to schedule posts, use a third-party tool like Later, Buffer, or Hootsuite, which connect to your Instagram account and let you schedule from a computer.

Why does my video look blurry after I upload it?

Instagram compresses videos to save storage space, which can reduce quality. Make sure your original video file is high quality (at least 1080p resolution) before uploading. Also check that your video is in the correct format (MP4 or MOV) and aspect ratio (9:16 for Reels and Stories, or 1:1 for feed posts). If it's still blurry, try uploading a smaller file size—very large files sometimes compress more aggressively.

Can I post multiple photos in one post from my computer?

The web version does not support carousel posts (multiple photos in one post). You can only upload a single image or video per post from a computer. To post multiple photos together, use the Instagram mobile app, which has a "Select multiple" option when you click the plus icon.

What happens if I close my browser before the upload finishes?

If you close the browser or lose your internet connection before the upload completes, the post will not be saved. You'll need to start over and select your file again. For large video files, make sure you have a stable internet connection and don't close the browser until you see the "Your post has been shared" message.

Can I post to Instagram from my computer without using the web version?

You can use third-party tools like Later, Buffer, or Meta Business Suite to post from your computer. These tools connect to your Instagram account and let you upload, schedule, and manage posts. Meta Business Suite is free and made by Instagram's parent company, so it's the most reliable option if you want an alternative to the web version.
