Instagram is really easy to use photo app where tweaking anything is easy, that includes adding, deleting or editing captions. You can add a caption to a photo or video you've already shared, or edit or delete the caption you originally included. To add, edit or delete a caption:
- Tap, 'three horizontal dots' if you are using an iPhone or 'three vertical dots' if you are using an Android phone, above your photo or video
- Tap Edit
- Edit, delete or add a caption, then tap Done
- When you tap the 'comment icon' (a small chat cloud) below a post, the word 'Edited' will appear above captions that have been edited.
