Make your Reels work without sound

Many people watch Reels on mute. Captions make sure your message lands anyway – and videos that are easy to follow get watched longer, which helps your reach.

Instagram’s caption sticker only offers a few looks. With HeyCaptions you can choose bold, minimal, karaoke or boxed styles, change colors and fonts, and correct any word before you post.

Captions that look the same everywhere

Your download is a normal MP4 with the subtitles burned in, so they look exactly the same on Reels, Stories, Facebook, WhatsApp Status and wherever else you share it.
