The best cross-posting tool for short-form video depends on where you film first. If you post on TikTok or Instagram and want the same video on Reels, Shorts and Facebook automatically, pick a reposting tool such as PostOnce or Repurpose.io. If you'd rather upload each video once and choose where it goes, pick an upload-once app such as Socialync.

Can you repost TikTok videos to YouTube Shorts and Reels?
Yes, you can repost your own TikTok videos to YouTube Shorts and Instagram Reels, since all three use vertical video. You can upload each video again by hand, or use a tool that reposts every new TikTok automatically. PostOnce does this for up to 9 networks after a 5-step setup.
Three ways short-form cross-posting tools work
Short-form video tools work in one of three ways:
- Automatic reposting. You post on TikTok, Instagram or YouTube as usual. The tool sees the new video and posts it to your other accounts. PostOnce, Repurpose.io, ShortSync and Nuelink work this way.
- Upload once. You upload the video to the tool, write a caption and tick TikTok, Reels and Shorts. Socialync, Post Bridge and Metricool work this way. (PostOnce and ShortSync can do this too.)
- Clip, then post. You give the tool a long video; it cuts short clips and posts them. OpusClip works this way.
If you film for one app and post every day, automatic reposting saves the most time: you never open the tool after setup. If every video gets its own caption per network, upload-once is easier.

How to cross-post TikToks to Reels and Shorts
- Connect your accounts. Instagram needs a Business or Creator account, and Facebook needs a Page.
- Pick the source. Choose the app you film for, such as TikTok.
- Pick the destinations. Choose Instagram Reels, YouTube Shorts and Facebook Reels.
- Turn the workflow on and post your next TikTok as usual.
- Check the first repost on each network, then let it run.
With an upload-once app, steps 2 to 4 become: upload the video, write a caption for each network, and choose a time.
Does cross-posting short videos hurt views?
No, cross-posting short videos doesn't hurt views on its own. These tools post through each platform's official API, like a scheduler. Across 40 YouTube channels that started posting through PostOnce, the share of Shorts under 10 views went from 9.8% to 9.5%, so there was no consistent drop.
PostOnce's founder grew How2Rizz to about 15k TikTok followers, 10k on Instagram and 4,800 YouTube subscribers posting the same videos everywhere through PostOnce.
Two things matter more:
- Account history. A brand-new account may get few views whatever tool you use. Post a few videos natively before you automate.
- Licensed music. The post goes out, but a destination network may mute or remove a video whose music rights don't carry over. Original audio travels best.
