Facebook Subtitle Generator — Captions for the Silent Feed
85% of Facebook videos play without sound. CutSnap helps you add accurate, styled captions to Facebook videos and Reels — burned into the video pixel-perfectly for silent autoplay, or as an SRT file for Facebook's caption upload feature.
Why It Matters
Why Facebook Videos Need Subtitles
Facebook's silent autoplay is the default. Videos that do not communicate their value in the first 3 seconds without sound get scrolled past. Captions are the most effective way to stop the scroll.

Tips
Facebook Caption Best Practices
Hook in the first 3 seconds
Facebook shows a brief preview before play. Your first caption block must immediately signal value to stop the scroll before the video even starts properly.
Large, high-contrast text
Most Facebook video is viewed on mobile. Use font sizes that are readable on a 5-inch screen and white text on a dark background for maximum contrast.
Upload SRT for accessibility and SEO
Facebook allows SRT uploads for video posts. This makes captions toggleable for users and may improve video discoverability in the feed.
FAQ
Does Facebook support external SRT caption files?
Yes. Facebook allows you to upload an SRT file when creating a video post. CutSnap exports both burned-in MP4 and SRT from the same project.
Should I use burned-in or SRT captions for Facebook?
Both. Use burned-in captions for the autoplay experience — they are always visible. Also upload the SRT file so users can toggle captions on/off if they choose.
Can I add captions to Facebook Live replays?
Yes. Download the Facebook Live replay as MP4 from your Page, upload it to CutSnap, add captions, and re-post as a regular video.
Does CutSnap handle Facebook's recommended video dimensions?
Yes. CutSnap handles all aspect ratios — 16:9 for standard Facebook video, 9:16 for Reels, and 1:1 for square feed posts.
