The basic steps to share a photo or video on Instagram

Creating a post on Instagram means uploading a photo or video from your phone or computer, adding text and tags if you want, and sharing it with your followers. The process takes about two minutes once you open the app. Instagram stores everything you post — your image, the caption you write, the date and time, and a record of who liked or commented — on their servers, which is why understanding what happens to that information matters.

You can post from the Instagram app on your phone (iPhone or Android), or from a web browser on a computer. The phone app is simpler for most people because it connects directly to your camera roll. The web version works if you prefer a larger screen or want to schedule posts in advance using Instagram's planning tools.

Key Takeaways

  • Open Instagram, tap the plus icon, select a photo or video from your phone, and tap Share to post it — the whole process takes under two minutes.
  • You can add a caption (text description), tag other accounts, add location information, and turn comments on or off before you share.
  • Once you post, Instagram stores your image, caption, and metadata (date, time, location) on their servers and shows it to your followers based on their algorithm.
  • You can delete a post anytime, but Instagram may keep copies of the data for a period even after deletion, depending on their backup systems.
  • If your account is public, anyone on Instagram can see your post; if it is private, only people you approve as followers can see it.

How to post a photo or video from your phone

Open the Instagram app and look for the plus sign icon at the bottom of the screen (on iPhone) or in the top right corner (on Android). Tap it. Instagram will show you your phone's photo library organized by date, with your most recent photos at the top. Scroll to find the photo or video you want to post, or tap it directly if it is recent.

Once you select an image, Instagram shows you a preview and asks whether you want to post a single photo, multiple photos (a carousel), or a video. Choose what you want and tap Next. You can now crop, rotate, or adjust the brightness and colors using the editing tools. These changes only affect how the post looks — they do not change the original file on your phone. When you are satisfied, tap Next again.

The next screen is where you add a caption (the text that appears below your image), tag other Instagram accounts, add a location, and choose whether to turn comments on or off. You can leave the caption blank if you want. When you are ready, tap Share. Your post is now live and visible to your followers (or to everyone, depending on whether your account is public or private).

Adding captions, tags, and location information

A caption is optional text that appears below your image. You can write anything — a description of the photo, a thought, a question for your followers, or nothing at all. Captions can be up to 2,200 characters long. Instagram stores whatever you write as part of your post data, so anything in a caption is recorded and can be searched by Instagram's systems.

Tagging means mentioning another Instagram account by typing the @ symbol followed by their username. When you tag someone, Instagram sends them a notification and links their profile to your post. The tagged person can see that you mentioned them, and their followers may see the tag depending on Instagram's algorithm. Tags are also stored as part of your post data.

Adding a location means selecting a city, neighborhood, or specific place (like a restaurant or landmark). Instagram will display the location name below your caption. This information is stored with your post and can be used to show your post to people searching for that location. You can add a location even if you were not actually there — Instagram does not verify your location against your phone's GPS.

Posting from a computer or web browser

You can post to Instagram from a computer by going to Instagram.com and logging in. Click the plus icon at the bottom left of the screen. Instagram will open a window to select a file from your computer. Choose a photo or video and click Open. The process is the same as on your phone — you can add a caption, tags, and location before clicking Share.

One advantage of posting from a computer is that you can use Instagram's scheduling feature. Instead of clicking Share when ready, you can click Schedule and choose a date and time for the post to go live automatically. This is useful if you want to post when your followers are most active but you are not available at that moment. Scheduled posts are stored on Instagram's servers until the scheduled time arrives.

Understanding what happens to your post after you share it

Once you tap Share, your image, caption, tags, location, and the date and time are sent to Instagram's servers. Instagram stores this information and uses it to decide which of your followers see the post first. The algorithm considers factors like how often someone engages with your posts, how recently you posted, and what type of content you usually share. Your post may appear in your followers' feeds when ready, or it may take hours depending on these factors.

Instagram also stores metadata — information about the image itself that you may not see. This includes the camera or phone model used to take the photo, the exact date and time it was taken, and sometimes GPS coordinates if your phone recorded them. This data is attached to the image file and is stored along with your post.

If your account is public, anyone on Instagram can find and see your post by searching your username, looking at your profile, or seeing it in the Explore section if the algorithm shows it to them. If your account is private, only people you have approved as followers can see your posts. You can change your account from public to private anytime, but posts you shared while public remain visible to anyone who saw them before you changed the setting.

Editing or deleting a post

You can edit a post after you share it by tapping the three dots in the top right corner of your post and selecting Edit. You can change the caption, turn comments on or off, or change the location. You cannot change the image itself — if you want a different photo, you must delete the post and create a new one. Any edits you make are recorded by Instagram, though you cannot see a history of what changed.

To delete a post, tap the three dots and select Delete. The post is removed from your profile and your followers' feeds when ready. However, Instagram may keep copies of the image and data on backup servers for a period of time. This is standard practice for large platforms — they keep backups in case of system failures. Eventually these backups are deleted, but the exact timeline is not public. Once a post is deleted, it is no longer searchable or visible to other users.

Privacy settings that affect who sees your posts

Your account privacy setting controls who can see all your posts at once. If your account is public, anyone can see your posts without following you. If your account is private, only people you approve as followers can see them. You can change this setting anytime by going to Settings, then Privacy, and toggling between Public Account and Private Account.

For individual posts, you can control whether comments are turned on or off. If you turn comments off, people can still see the post and like it, but they cannot write comments below it. You can also block specific people from seeing your posts, or restrict accounts so their comments are hidden unless you approve them first. These settings are found in the three-dot menu on each post.

Frequently Asked Questions

Can I post the same photo to Instagram multiple times?

Yes, you can post the same photo as many times as you want. Instagram does not prevent duplicate posts. However, posting the same image repeatedly may cause your followers to see it as spam, and the algorithm may show it to fewer people if engagement is low.

What happens if I post something and then change my mind?

You can delete the post anytime by tapping the three dots and selecting Delete. The post disappears from your profile and feeds when ready. Instagram may retain copies on backup servers temporarily, but the post is no longer visible to other users or searchable.

Do I have to add a caption to my post?

No, captions are optional. You can post a photo or video with no text at all. However, captions often increase engagement because they give followers context or encourage them to comment.

Can I post a video longer than a few minutes?

Instagram allows videos up to 60 minutes long if you post them as Reels, or up to 10 minutes in your regular feed. Videos longer than that must be edited down or posted to Instagram's video service, IGTV, which has different length limits.

What if I want to post something but hide it from certain people?

You can make your account private so only approved followers see your posts, or you can restrict specific accounts so they cannot see your posts at all. You can also turn off comments for individual posts. There is no setting to hide a post from some followers but not others while keeping your account public.
