3 Proven Ways to Post YouTube Videos on Instagram 2025

If the YouTube video you intend to post on Instagram is not in MP4, MOV, etc. format, you convert the video to a suitable format via YouTube to Instagram converter. Plus, you can compress the video file size and reduce its length.

How to Post YouTube Videos on Instagram from Computer

Instagram does not allow the straight upload of in-feed videos and stories on the computer. You have to finish it via 2 actions.

First, Download and Convert YouTube Video to Instagram

Here I pick the best YouTube to Instagram converter for Mac, Windows, and online.

For Mac and Windows Users

Second, Upload the Converted Video to Instagram on Computer

Instagram hasn't developed an app for desktop operating systems. And the website version only lets you upload videos to IGTV. To share YouTube videos to Instagram in-feed posts and stories, INSSIST | Web Client for Instagram will help you.

It's a free Chrome extension powered by inssist.com. The plugin gives you the same excellent experience as using Instagram on your mobile phone. You can easily post videos, photos, stories, etc., and send DMs on computer.

1. Find INSSIST | Web Client for Instagram on the Chrome web store, and add it to Chrome.
2. Click the extensions icon to the right of the address bar. In the drop-down menu, click the INSSIST icon.
3. When the web page is opened, sign in your Instagram account.
4. Hit the “+” button, and choose to post story, photo/video, or IGTV video to Instagram on computer.

How to Post Videos on Instagram from YouTube Online

If you want to do it without software, you can have a try on Tube2Gram.com. It’s sometimes mistakenly written as TubeToGram or YouTube2gram.

Tube2Gram enables you to download YouTube videos. You just need to copy and paste the YouTube URL into the program.

It claims to have the ability to directly post YouTube to Instagram, Twitter, and other platforms. Based on my test, however, there is only a download option but no share one.

If you are a mobile phone user, Tube2Gram is good to use. So, I take a mobile phone as an example below.

1. Open the web browser, and go to Tube2Gram.com.
2. Select a video download type - Instagram Video, Twitter Video, or Other.
3. Paste the URL of the YouTube video.
4. Drag the orange slider to select the section of the video you want to download or enter the start and stop time manually.
5. Click on “Start Download”.
6. Once ready, hit “Download on Mobile”. For IOS users, enter your email address to get the YouTube video.
7. Open the Instagram app and upload the YouTube video to your Instagram.

Is Tube2Gram Safe?

Yes, Tube2Gram is safe. I got no virus from the website.

But it’s full of ads and loading slowly. You have to take a longer time to download YouTube videos when compared to third-party software.

Tube2Gram Not Working? Here’s the Alternative

Yttoig is an awesome online YouTube to Instagram converter that’s similar to Tube2Gram. It helps you upload custom thumbnails to maximize clicks.

It's not free but offers 7-day free trial. You need to pay $12/month (up to 5 videos), $18/month (up to 30 videos), or $32/month (unlimited videos).

The most important reason I think Yttoig is the best Tube2Gram alternative is that it can share YouTube videos to Instagram directly on the computer online.

1. Visit Yttoig.com.
2. Paste the copied link to the YouTube video into the address field, and click "Let's go!".
3. Choose a segment of the video you are going to post and click “Next”.
4. Add a caption to your Instagram video.
5. Remove YT to IG logo (pay $3) or not.
6. Click "Continue with watermark" or "Log into Instagram" (for users who have removed the watermark), and enter the login details of your Instagram account.
7. Click "Post your video" for sharing YouTube videos on Instagram.

Can I Post YouTube to Instagram with GramKeep?

No, you can’t. Although GramKeep.com is 100% free, it’s just an Instagram photo and video downloader. It doesn’t empower you to download YouTube videos.

How to Share YouTube Video on Instagram with Mobile Apps

It’s simpler to finish this task on iPhone and Android, as you can upload videos in Instagram app on mobile without extra steps.

On iPhone

We also found an extremely simple and convenient method, which supports directly downloading YouTube videos to your iPhone's Camera Roll. Using an app named Video Download Browser.

1. Download this app for your iPhone. Launch it and open YouTube to find the video you need to download.
2. Just play the video in the app, and it will pop up a "Save to Memory" option, click on it, the app will start to download the video instantly.
3. After your video has downloaded, navigate to the Videos tab from within the app, choose information and select "Save to Camera Roll".
4. Launch the Instagram app and add a new post as usual. Choose the downloaded YouTube video in your Camera Roll. Now, you are ready to post your YouTube video to Instagram.

On Android

TubeMate is the most popular Android YouTube video downloader, and it can also work as a YouTube to an Instagram downloader.

1. Download TubeMate in Google Play and install it on your Android phone.
2. Launch TubeMate and browse YouTube to find the YouTube videos you want to download. Or, you can also tap the menu in the top right and select 'URL' to add the URL of a YouTube video.
3. Play or paste the URL of the YouTube video within this app, a bright green download button will appear. Tap on it and this app will start to analyze the downloadable video format.
4. Choose output format (MP4) for sharing on Instagram.
5. Then the video will be saved to your phone and you can start sharing it on Instagram.

Conclusion

Okay, so above are the 3 methods that I recommend to use for posting YouTube videos to Instagram. You’d better install YouTube to Instagram converters + Chrome plugin to upload videos on computer. In addition, Tube2Gram is actually also an online converter. Unlike Yttoig, it doesn’t provide an option to share Instagram videos.
