You can't post a YouTube video to Instagram directly. Instagram has no YouTube import, and a YouTube link pasted into a post caption isn't clickable for most accounts. That leaves two options: share the link, ideally in a Story with the link sticker, or upload the video file itself as a Reel or Story, which only makes sense for videos you own.
For your own videos, the best route is to take your original export (or download it from YouTube Studio), cut a vertical 9:16 clip that runs under three minutes, and post it as a Reel that points people to the full video.
Below are the exact steps for both options, a comparison of Instagram's video formats, and a workflow for keeping YouTube and Instagram updated without doing everything twice.
Why post your YouTube videos on Instagram?
Reach people who don't search YouTube
Your YouTube audience mostly finds you through search and recommendations on YouTube. Instagram users discover videos while scrolling Reels and Stories. Posting a cut of your video there puts it in front of people who may never have searched for your topic.
Get more from every video you make
A ten-minute YouTube video usually contains several moments that work on their own: a strong tip, a surprising result, a funny outtake. Each of those can become a Reel. You already did the hard part, which is filming and editing. Reusing it is far cheaper than making something new.
Option 1: Share the YouTube link
If you just want to point people to a video, whether it's yours or someone else's, share the link. You aren't re-uploading anything, so there are no rights issues.
Add a YouTube link to your Story
- In the YouTube app, open the video, tap Share and tap Copy link.
- In Instagram, start a new Story. Use a screenshot of the video, its thumbnail or a short teaser clip as the background.
- Tap the sticker icon at the top and choose Link.
- Paste the YouTube URL, add custom sticker text if you like ("Watch the full video"), and tap Done.
- Place the sticker where people will see it and share the Story.
Instagram opened the link sticker to all accounts in 2021, though it says new accounts and accounts that repeatedly break its guidelines may not have access. For more detail, see our guide on adding a link to an Instagram Story.
Put the link in your bio
Your bio link is the one permanent clickable link on your profile. Update it when a new video goes live, then mention "link in bio" in your Reel captions and Stories. Save the Story to a Highlight so the link stays visible after 24 hours.
Send it in a DM
Paste a YouTube link into an Instagram direct message and it shows as a clickable link. Good for sending a video to a specific person or a group chat.
Option 2: Upload the video itself
If the video is yours, uploading it natively as a Reel is the stronger move. Viewers can watch without leaving Instagram, and Reels can be recommended to people who don't follow you.
Step 1: Get the video file
Use your original export from your editing app whenever you can. It's the highest-quality version you have.
If you no longer have it, YouTube lets you download your own uploads. Sign in to YouTube Studio on a computer, select Content in the left panel, open the menu next to the video and choose Download. According to YouTube's help center, you get an MP4 in 720p or 360p depending on the video, and you can download each video up to five times a day. Downloads aren't available for videos with a copyright or Community Guidelines strike or videos that use a preapproved audio track. You can't download other people's videos this way.
Step 2: Resize for a vertical screen
Most YouTube videos are 16:9 landscape. Reels are 9:16 vertical, 1080 x 1920 pixels. Open the clip in an editor like CapCut, Premiere Pro, DaVinci Resolve or Final Cut Pro, set the project to 1080 x 1920, and then:
- Reframe to follow the speaker or main action, if there's one clear subject.
- Stack the landscape clip in the middle with a headline above and subtitles below, for screen recordings and talking heads with B-roll.
- Add subtitles. Many people scroll with the sound off.
Keep text out of the bottom third and the right edge, where Instagram places the caption and buttons. Our Instagram Reel size guide has the exact safe zones.
Step 3: Trim for impact
Instagram allows Reels up to 3 minutes as standard, and longer uploads have been rolling out, but Instagram recommends keeping Reels under 3 minutes because longer ones get limited reach beyond your followers. In practice, a 20 to 60 second clip is often enough:
- Open with the most interesting moment, not the intro.
- Cut every pause and filler line.
- End with a reason to watch the full video: "Part two is on YouTube, link in bio."
Step 4: Choose the right placement
| Feature | Reels | Stories | Feed video |
|---|---|---|---|
| Best size | 1080 x 1920 (9:16) | 1080 x 1920 (9:16) | Shared as a Reel in most cases |
| Length | Up to 3 minutes recommended | Up to 60 seconds per clip | Same as Reels |
| Clickable link | No (use "link in bio") | Yes, with the link sticker | No |
| Reaches non-followers | Yes | Mostly followers | Same as Reels |
| How long it stays up | Permanent | 24 hours, or permanent in a Highlight | Permanent |
| Best for | Discovery and new followers | Driving clicks to YouTube | Not usually a separate choice |
Instagram shares most new video posts as Reels, so your real choice is Reel, Story or both. Many creators do both: post the Reel for reach, then share it to their Story with a link sticker for clicks.
Step 5: Write the post
- Cover: pick a frame or upload a cover with a short title. Keep it in the center, since the profile grid shows a 3:4 crop.
- Caption: say what the viewer gets in the first line, then point to the full video.
- Music: if your YouTube video uses licensed music, Instagram may mute or restrict it. Consider swapping in audio from Instagram's library.
Post to YouTube and Instagram from one place with ViralFarm
Copying files between apps and rewriting captions twice is where cross-posting usually falls apart. ViralFarm publishes to both YouTube and Instagram, plus TikTok, Facebook and four other networks, from one queue and calendar.
Upload your vertical cut once, schedule it as a YouTube Short and an Instagram Reel, and give each its own caption. Your full-length YouTube upload can stay on YouTube, while the shorter cuts do the work of sending people there. The free plan covers 2 channels and 20 published posts a month.
Smarter cross-platform video promotion
Customize for each platform
YouTube titles are written for search. Instagram captions are written for people scrolling. Rewrite the hook for each one instead of pasting the same text. Hashtags matter less than a clear first line on Instagram, and a few relevant ones are plenty.
Start with Shorts
If you already make YouTube Shorts, they're the easiest videos to bring over. They're already vertical and short. Upload the original Short file, not a downloaded copy, so it stays sharp.
Time it to the YouTube release
Post the Reel on the same day your full video goes live, then share it to your Story with the link sticker. The Reel builds interest, and the Story gives people a one-tap way to the full video while it's fresh.
Frequently asked questions
Can I upload the same video file to YouTube and Instagram?
Yes, if it's yours and in the right shape. A 1080 x 1920 vertical video under 3 minutes works as both a YouTube Short and an Instagram Reel. A 16:9 long-form video needs to be cut down and reframed before it works well as a Reel.
Can I share someone else's YouTube video on Instagram?
Share the link, not the file. Linking in a Story, your bio or a DM is fine. Downloading someone else's video and uploading it to Instagram without permission can infringe their copyright, and YouTube doesn't let you download other people's videos in YouTube Studio anyway.
Why isn't my YouTube link clickable in my Instagram caption?
Instagram doesn't turn URLs in post captions into links for most accounts. Use the link sticker in a Story, your bio link or a DM instead.
How long can my YouTube clip be on Instagram?
Reels can be up to 3 minutes as standard, and Instagram recommends staying under that for the best reach. Each Story clip can be up to 60 seconds.
Why does my YouTube video look worse on Instagram?
Usually because the file was compressed more than once, for example by downloading a 720p copy from YouTube and then uploading it to Instagram. Use your original export, export at 1080 x 1920, and turn on Upload at highest quality in Instagram's Media quality settings.
Can I post a YouTube video to Instagram from my computer?
Yes. You can create posts on instagram.com in a desktop browser, and scheduling tools like ViralFarm let you upload and schedule Reels from a computer. Story link stickers are added in the Instagram app.
Share the link when you want clicks, upload a vertical cut when you want reach, and do both when a new video goes live. When you want both channels on one calendar, Start free — no credit card required.
