How do I add captions to a Facebook video?

Drop your video into ReelCaption, let it transcribe the audio, style the captions to read clearly, then export a burned-in MP4 to upload to Facebook as a feed video or a Reel.

Do captions matter on Facebook if it has auto-captions?

Facebook can auto-generate captions, but they are toggleable and often inaccurate. Burning in your own edited captions guarantees they always show and read correctly.

Can I use the same video for a Facebook Reel?

Yes. Export a vertical 9:16 version with captions kept centered and a little high, clear of the Reels overlay, and it is ready to post.

Yes, 5 minutes of captions a month with no card, then $5/mo for Pro.

Add captions to your Facebook videos and Reels

Most Facebook video plays start on mute, and a large share of the audience watches without ever turning sound on. Captions decide whether they keep watching. ReelCaption transcribes your video and burns in captions you can style, right in your browser.

How to add captions to Facebook

1Open ReelCaption and drop in your Facebook video or Reel (wide for feed, vertical for Reels).
2It auto-transcribes the speech into word-perfect captions with per-word timing.
3Edit any wording, fine-tune timing on the timeline, then style it with a bold, high-contrast font so it reads across all phone and desktop screens.
4Position the captions clear of the Reels overlay, then export a burned-in MP4.
5Upload to Facebook as a feed video or a Reel. The captions are baked in, so they show on every device.

Tips for Facebook

Facebook serves video to a broad age range on phones and desktops, so high-contrast, easy-to-read captions matter more than trendy effects.
For feed videos, 16:9 or square works; for Facebook Reels, go vertical 9:16. ReelCaption keeps whatever size you bring.
Burned-in captions show even though Facebook autoplays muted, so you are not relying on the viewer to enable subtitles.
Keep Reels captions centered and a little high to avoid the title and action buttons at the bottom and right.
