How to Add Captions to Instagram Reels on iPhone

By the iPhone Captions editorial team · Updated 2026-06-28

Captions matter on Reels because most people watch muted. You have two ways on iPhone: Instagram's own captions sticker for a quick job, or a captioning app first when you want your own style and a cleaner result.

How do I add captions to an Instagram Reel?

Fastest: in the Reel editor, tap the sticker icon and choose the Captions sticker — Instagram auto-transcribes your audio. For more control (custom fonts, word-by-word animation, brand style, offline), caption the video in an app like Subly first, then upload the finished clip to Reels.

Option 1 — Instagram's captions sticker

  1. Add your clip to a Reel. Record or upload, then move to the editing screen.
  2. Open stickers. Tap the sticker icon at the top.
  3. Pick 'Captions'. Instagram transcribes the audio automatically.
  4. Edit and style. Fix any wrong words, choose a text style and color, and reposition.

Free and quick, but the styling is limited, it only works inside Instagram, and you can't reuse the captioned video elsewhere.

Option 2 — caption first in an app

Captioning before you upload gives you a custom look (fonts, word-by-word highlight, brand colors), one captioned file you can post to Reels, TikTok and Shorts alike, and it works offline. Burn the captions in, then upload to Reels as a normal video.

Keep captions in the middle of the frame, clear of the Reels UI — the right side (icons) and bottom (caption/handle) get covered.

Frequently asked questions

Does Instagram add captions to Reels automatically?
Yes — the Captions sticker auto-transcribes your audio. Open stickers in the Reel editor and pick 'Captions', then correct any errors. It's free but styled only lightly and stays inside Instagram.
Why aren't my Reel captions showing?
If you used a standalone SRT it won't display — Instagram needs captions from its sticker or burned into the video. Also check you didn't place the text under the Reels UI, where it's hidden behind icons.
Can I use the same captioned video on TikTok and Shorts?
Yes, if you caption it in an app and burn the text in. Instagram's sticker captions only live inside Instagram, so for cross-posting, caption in an app first.
