Frequently asked questions
Why add captions to Instagram Reels?
Instagram reports that 40% of Stories and Reels are viewed without sound. Captions ensure your message gets across regardless, increase average watch time, and make your content accessible to a wider audience.
What's the difference between Story captions and Reel captions?
Stories are 9:16 vertical and disappear after 24 hours, so bold and simple captions work best. Reels are also 9:16 but live on your profile permanently — they benefit from more polished, on-brand caption styling that matches your feed aesthetic.
What caption styles perform best on Instagram?
Clean sans-serif fonts with a subtle text shadow or background box perform well on Instagram. Word-by-word highlight animations are trending. Keep font sizes large enough to read on mobile and leave margins so captions don't overlap the UI.
Can I export directly to Instagram from this tool?
The tool exports a finished MP4 file with captions burned in. You can then upload that MP4 directly to Instagram as a Reel or Story — no extra steps needed.
