Environment

Resolution
Automatic alt-text
Instagram uses automatic object-recognition software to make a best guess at alt-text for posts. It is helpful but not always accurate, so add your own alt-text whenever you can.

Add alt-text to a new post
- Start uploading a new photo, edit the image and add filters, then tap Next.
- On the caption screen, tap Advanced Settings.
- Under Accessibility, tap Write Alt Text.
- Enter your description and finish posting.
Add alt-text to an existing post
- Go to the photo and tap the three-dot (...) menu in the top-right.
- Tap Add Alt Text.
- Write the alt-text and tap Done.
Caption your videos
Any video posted to a story, reel, or feed post should have captions if it includes speech or music.
Open captions only. Instagram supports only open captions — text added directly to ("burned in") the video that cannot be turned on or off — so add captions when you edit the video. Captions should be synchronized and matched to the spoken words. Follow the DCMP Captioning Key (see Additional Resources) for caption style.
Captioning software by platform
- Mac: iMovie, Final Cut Pro, Adobe Premiere, Headliner.app
- Windows: Microsoft Clipchamp / Movie Maker, Adobe Premiere
- iPhone / iPad: iMovie, Adobe Premiere Rush, Apple Clips, Clipomatic
