Captions for Instagram Reels, done for you
Reels autoplay muted in the feed, so a Reel without captions is a Reel most people scroll past. InstaZap adds them automatically, cuts the pauses out of your delivery, and gives you back a 9:16 file ready to post.
Preset: balanced cut, Punch captions, 9:16

Why it works for this
Readable in the feed
One line at a time, sized to the frame, with the word being said picked out in colour. It reads at thumbnail size and doesn't crowd the picture.
Your delivery, tightened
The pauses between sentences — the ones you don't notice while talking — are cut. A Reel that was 47 seconds comes back at 31 with nothing missing.
An SRT for the edit
Alongside the video you get a subtitle file. If Instagram's own caption tool is what you use for accessibility, upload the SRT there too.

Questions
Which caption style works best for Reels?
Punch is preset — it's the bold, word-highlighted look that's standard on Reels. If your brand is quieter, Clean keeps the same word timing with white text and a thin outline.
My video is landscape. Can it become a Reel?
Yes. The 9:16 option crops to the middle of the frame and delivers a vertical file. It's on the Creator plan; if you're on the free tier the video is delivered in its original shape.
How long can the Reel be?
Free accounts can process videos up to 60 seconds. Creator takes up to three minutes and Pro up to ten, which covers the 90-second Reel limit with room to cut.
Your first 3 are free, and we don’t keep your video
No card to start. The upload is deleted as soon as it’s processed and the result 24 hours after it’s ready. Nothing is used to train anything.
