Add Captions to Instagram Reels
A lot of Reels get watched with the sound off. CapGen adds accurate, styled captions to your Reel in minutes — free, no watermark, no Instagram account needed.
Real output — “Karaoke Green” style, genuinely rendered by CapGen. Clip: “Tears of Steel” (mango.blender.org), © Blender Foundation, CC BY 3.0. See more styles
Reels get watched on mute
Scrolling happens everywhere — on the bus, in bed, at work. Captions keep your Reel understandable the instant it starts, sound or no sound.
Confused viewers scroll away
If someone can't follow what's being said, they swipe to the next Reel. Clear captions keep them watching to the end.
It's accessible by default
Deaf and hard-of-hearing viewers, and anyone in a loud room, can follow along — captions widen your real audience.

Real browser editor
Fix any word, retime, reposition, or restyle before you export — no desktop software.

FAQ
Questions, answered
Does CapGen work with Instagram's 9:16 vertical format?
Yes — your output keeps the exact resolution, frame rate, and aspect ratio of your source, so it drops straight into Reels without cropping.
Do I need to connect my Instagram account?
No. Upload a video file directly — there's no Instagram login or API connection involved. You download the finished clip and post it yourself.
Can I match my own caption style?
Yes — pick from several built-in looks (including the bold word-by-word karaoke highlight popular on Reels) and customize color, size, and position per caption.
Is it really free?
