Best Repost Apps for TikTok, Instagram Reels and YouTube Shorts (2026)

· 4 min read

“Repost” means different things depending on what you’re trying to do, and the best app depends on which one you mean:

  • Sharing someone else’s post with your followers → use the app’s own Repost button. Free, credited, no download.
  • Posting your own video on other apps (TikTok → Reels, Shorts, Facebook) → use a reposting tool that publishes a clean copy automatically.
  • Posting your own old video again → reschedule it, ideally improved, with a tool or by hand.

This guide covers the best option for each, including free ones, and what to avoid.

The best repost apps and tools at a glance

Tool What it reposts Automatic Price
TikTok Repost button Others’ TikToks to your followers No Free
Instagram Repost button Others’ public posts and Reels to your followers No Free
X Repost Others’ posts to your followers No Free
Repostit Your videos and images to TikTok, Instagram, YouTube, Facebook, X, Threads, LinkedIn, Pinterest Yes From $5/month, 14-day free trial
Repurpose.io Your videos, audio and livestreams to many apps Yes From $35/month
Schedulers (Buffer, Metricool…) Posts you upload again yourself Scheduled Free tiers available

1. Reposting other people’s content: use the built-in buttons

TikTok Repost

Tap Share on any video, then Repost. It shows to your followers with the original creator credited, and appears in your Reposts tab (and on your profile grid if you turn that on in Privacy → Repost settings). To undo, tap Share again and Remove repost.

Instagram Repost

Instagram added a Repost button for public posts and Reels in 2025. Reposts appear in your followers’ feeds and in a Reposts tab on your profile, credit the original creator automatically, and notify them. Tap the repost icon again to remove it.

X Repost

The classic retweet, now called Repost, with an option to quote it with your own comment.

Why not download and re-upload others’ videos? It removes credit, can trigger copyright claims, and every major app limits reach for unoriginal re-uploads. In October 2026 YouTube was reported to be cutting reach further for Shorts re-uploaded without added value. Use the native button, or ask the creator for permission and credit them clearly.

2. Reposting your own videos to other apps: use a reposting tool

This is where the real growth is. Your TikTok audience and your Instagram, YouTube and Facebook audiences are mostly different people, so a video that did well on one app is new content on the others.

Repostit

Connect your accounts with each app’s official sign-in, create a workflow such as TikTok → Instagram Reels, YouTube Shorts, Facebook Reels, and every new post is published to the others automatically:

  • No watermark. The TikTok logo is removed, so other apps don’t limit the video’s reach.
  • Resized and formatted per app, with your caption and hashtags.
  • Videos, images and carousels, for new posts and your back catalogue.
  • Manual or Auto: approve each repost, or let it run.
  • Publishes to TikTok, Instagram, YouTube, Facebook, X, Threads, LinkedIn and Pinterest.

Plans start at $5 a month; unlimited reposting is $10 a month on yearly billing. Free for 14 days, no card.

Repurpose.io

Broader and pricier: also handles audio, livestreams and destinations such as Snapchat and Amazon. From $35 a month. See our Repurpose.io review.

Schedulers

Buffer, Later, Metricool and similar tools post what you upload to them. They don’t fetch your TikToks automatically or remove watermarks, but free plans exist. Comparison: free and cheap alternatives.

3. Reposting your own old videos

Repost apps and bots to avoid

  • Apps that ask for your password. Legitimate tools use the official “Continue with TikTok / Instagram / Google” sign-in.
  • “Repost bots” that auto-repost other accounts’ content to grow a page. They break platform rules and copyright, and accounts built this way get demonetised or removed.
  • Downloaders that keep the watermark when you repost to another app. Instagram and YouTube show those videos less.
  • Browser extensions with broad permissions you don’t need. Check what they can access before installing.
Four warning signs: asks for your password, reposts other accounts, keeps the watermark, browser extensions with broad access
