What this Reels captions tool does
SubtitlePop writes Reels captions from the speech in your video and burns them into the picture in the style you choose. Because the captions are part of the video, every viewer sees them — in the feed, in Stories and when the Reel is shared.
Upload the finished Reel, fix names and handles, pick a caption style and export the MP4. Captions for Reels up to 3 minutes fit in the free plan, and the same result also downloads as an SRT file for Facebook.
How to add subtitles to a Reel
Upload the Reel
The finished vertical video, before you post it.
Pick a style and position
Highlight is the default; move captions up if your Reel has text near the bottom.
Export and post
Choose Export → Video with captions, then upload the MP4 to Instagram as a new Reel. An SRT file is there too if you post the video on Facebook.
Where Instagram covers Reels captions
Instagram places the account name, caption and audio at the bottom of a Reel and the action buttons along the right edge. Captions sitting a third of the way up the frame stay clear of both. Instagram also offers auto-generated captions that viewers can turn on; captions in the video itself are visible to everyone and carry your style.
Reels captions that keep viewers
- Lead with the point. The first caption is what stops the scroll.
- Keep lines short. Two to four words read in a glance on a phone.
- Stay out of the bottom. Instagram draws the caption text, audio label and buttons over the lower part of a Reel.
- Match the mood. Highlight for talking to camera, Box for calm tutorials, Bold yellow for high energy.
One set of Reels captions for every placement
The same result can be posted as a Reel with captions burned in, uploaded to Facebook with an SRT, and reused for a Story. Export the MP4 for Reels and keep the subtitle file for platforms that accept one.
Caption styles for different kinds of Reels
Talking to camera
Highlight keeps a whole phrase on screen and shows which word is being said.
Tutorials and recipes
Box or Clean, in sentence case, so steps read like instructions.
Promos and hooks
Word pop or Bold yellow for a few seconds of high energy.
