Kool Captions Open the app
Instagram Reels

Add captions to your Instagram Reels, free

Upload your reel and get word-by-word captions sized for Instagram, timed to your voice — Hinglish or your language — ready to post in minutes.

Why captions matter on Reels

Most Reels are watched on mute in the feed, so a reel with no captions loses the viewer in the first second. Captions hold attention, make the hook readable, and open your reel to anyone scrolling silently — which is almost everyone. Word-by-word captions in the style creators use are the ones people actually stop for.

How to add captions to a Instagram Reel

  1. Upload your reel and pick Hinglish or your language. Paste your script if you have one.
  2. Pick a style and fix anything. Every word is already timed — choose one of 56 looks, tweak the font and position, fix any word.
  3. Export in 9:16 at 720p, 1080p or 4K, made right in your browser, then post straight to Instagram.

Everything you get

Word-by-word timing

Each word appears exactly as it is said — the karaoke style that holds viewers — not a whole line at once.

56 caption styles

Pop-ins, boxed and outlined looks. Pick one, then change the font, colour, size and position.

The key word, emphasised

One word per caption is highlighted — numbers, money, power words — with an optional emoji and a quick zoom.

Paste your script

Have the script? Paste it before transcribing and the captions follow your spelling, timed to your voice.

Cleaner voice, music underneath

One switch removes hiss and room noise and sets the volume Instagram and YouTube expect; add music and it ducks under your voice.

Export up to 4K, or .srt

720p, 1080p or 4K made in your own browser, or an .srt file for any other editor.

Questions

Do captions really increase reel views?

Most feed views happen on mute, so captions keep silent viewers watching, which is what the algorithm rewards. They also make your reel accessible to more people.

What size are the captions?

The whole frame is 9:16 for Reels; captions are positioned in the safe zone so Instagram’s UI never covers them. You can move them anywhere.

Can it do Hinglish and other Indian languages?

Yes — Hinglish in Roman letters, plus Hindi, Tamil, Telugu, Marathi, Bengali, Punjabi and Gujarati.

Is it free?

Yes — 3 free videos with the whole editor, no card. Sign in with Google.
