How to repurpose YouTube Shorts to Facebook Reels in 2026

Move YouTube Shorts to Facebook Reels with watermark removal, native upload, length trim, and Facebook-shaped captions. Workflow plus Kompozy automation.

Last verified · 2026-05-22 · by Moe Ameen

YouTube Shorts and Facebook Reels share aspect ratio (9:16), captioning model, and similar length expectations. The repurpose is technically simple but creators routinely break it by uploading the YouTube version with the burned #shorts text overlay or by crossposting through a third-party scheduling tool that flags as automated.

The right move is a native Facebook page upload with Facebook-shaped caption text (sentences, not hashtag stacks) and a length trim to 88 seconds maximum.

Why repurpose YouTube Shorts to Facebook Reels

Creators with both YouTube and Facebook surfaces use this move to extend YouTube Shorts content to the older Facebook demographic. Most effective for evergreen niches — finance, real estate, parenting, faith, home services.

About the source: YouTube Shorts

YouTube Shorts 9:16 master file up to 3 minutes / 256 GB. SRT export from YouTube Studio. AAC-LC audio.

About the destination: Facebook Reels

Facebook Reels caps at 90 seconds, 9:16, 4 GB. Native captions or SRT side-car. Caption text up to 2,200 chars. Native page upload outperforms third-party scheduler crossposts.

The workflow

  1. Download the Shorts master from YouTube Studio. Use YouTube Studio download for original quality. Avoid third-party downloaders.
  2. Trim to 88 seconds maximum. Facebook Reels strictly enforces 90s cap. YouTube Shorts can run up to 3 min — trim if needed.
  3. Strip the #shorts text overlay if it is burned-in. Many Shorts have an on-screen "#shorts" overlay near the top. Crop or blur it before uploading to Facebook.
  4. Upload natively to the Facebook page via Meta Business Suite. Avoid third-party schedulers for this — Facebook flags many of them as automated and demotes reach.
  5. Write Facebook-native caption (sentences, not hashtags). Drop the YouTube Shorts caption format. Use 80-150 chars of conversational hook before any hashtag.
  6. Use native Facebook captions or upload SRT. Both work; SRT enables auto-translation which helps international Facebook audiences.
  7. Schedule for 8-11 AM or 7-9 PM local time. Facebook Reels peaks in commute and wind-down windows.

Frequently asked questions

Can I just crosspost from YouTube to Facebook automatically?

Many third-party schedulers do this but get flagged as automated. Native upload via Meta Business Suite consistently outperforms.

What is the Facebook Reels length cap?

90 seconds hard. YouTube Shorts can run up to 3 minutes; trim if needed.

Should I keep the #shorts overlay?

Strip it. The overlay signals lazy repurpose to Facebook viewers.

Native captions or SRT side-car?

Both work. SRT enables auto-translation across languages which helps international Facebook audiences.

When should I post?

8-11 AM or 7-9 PM local time. Stagger across the week; one Reel per day per page maximum.

Can Kompozy do this end-to-end?

Yes — Kompozy pulls the Shorts master, trims to 88s, strips #shorts overlays, uploads natively via Meta Business Suite, drafts Facebook-shaped captions. Typical run: 2 minutes.
