How to Make an Image Square: Ultimate Guide (2026)
Learn how to make any image square without cropping out important content, using your phone's built-in editor, free web tools, or Instasize.

Instagram lets you fix a caption, tags, or location on a post at any time after it's live — no need to delete and repost. Here's exactly what you can change, what you can't, and how.
Open Instagram App
Start by opening your Instagram app on your phone.
Go to Your Profile
Tap on your profile picture at the bottom right corner to go to your profile page.
Find the Post You Want to Edit
Scroll through your posts to find the one you need to edit.
Tap the Three Dots
Tap the three dots in the upper right corner of the post.
Select 'Edit'
From the menu that pops up, select 'Edit'. Now you can change the caption, add or remove hashtags, and tag people.
Save Changes
Once you're happy with the changes, tap 'Done' (iPhone) or the checkmark (Android) to save.
Editing a post gives you the chance to:
Use Instasize for Image Edits
Before uploading, use the Instagram image resizer to resize, crop, and optimize your images. Instasize can also help you add borders and backgrounds to make your posts stand out. It is also worth checking your Instagram caption formatting before publishing, because the media itself cannot be swapped afterward.
Check Hashtags
Make sure your hashtags are still relevant and trending.
Engage with Comments
Editing your captions can re-ignite conversations in the comments section.
Nope, you can't change the actual photo or video once it's posted. But you can use the tips above to edit the caption, tags, and other details.
If the 'Edit' option isn't showing up, make sure your app is updated to the latest version. Sometimes, restarting the app or your phone can help, too.
There's no limit! Edit as many times as you need to get it right.
No, followers don't get a notification when you edit a caption, tag, or location. The only visible sign is the word "Edited" appearing under the caption when someone taps the comment icon — it doesn't say what changed.
Yes — the edit option is available on instagram.com as well as the mobile app, though most people find it faster to make small caption or tag fixes from the app.
