How to Post a TikTok Video on Instagram

Filmed within the app, TikTok videos are vertical or 9:16. But Instagram doesn’t allow you to share full 9:16 videos. The max size for an Instagram Post is 4:5, so TikTok videos are automatically cropped. To post TikTok videos on Instagram without cropping, you need to use a video resizer.

In this tutorial, I'll show you how to post a TikTok video on Instagram for free without cropping out the top and bottom of the video.

Instagram doesn't allow people to publish posts that are taller than 4:5, so 9:16 videos don't meet the requirements. To avoid cropping out the TikTok watermark and parts of the video, you'll need to resize the video by adding a background behind it. This tutorial uses a free online video editor called Kapwing (it works for images and videos too).

TikTok Videos are Hilarious

Why post TikTok Videos on your Instagram? Because they are hilarious!

Posting TikTok videos is a fun way to show off a music video you filmed or production you created. People put a lot of work into TikTok videos, so why not publish them on your Instagram or Finstagram for the world to see? This same technique applies for any narrow, 9:16 video you film or have saved on your phone.

In this article, I’ll describe how to resize your videos so that you can post TikTok videos on Instagram in 3 easy steps:

  1. Save the TikTok Video
  2. Change to 1:1 or 4:5 ratio
  3. Create and Publish

This tutorial uses free video editing software called Kapwing. Kapwing works on both your phone and computer, and you won’t need to download any software to use it.

Step 1: Save the TikTok Video

The first step is to save the TikTok video you want to repost into your camera roll. For most videos on TikTok, this step is simple. When you long-press on a video, an action menu pops up with an option to "Save Video." Click this open to download the video to your camera roll.

Some videos, however, do not have this option. TikTok recently released an update that allows video publishers to turn off a download option for anyone that sees their video. However, you can still download these blocked TikTok videos easily by using an online video downloader.

How to Download TikTok Videos

First, click the "Share" icon (the large arrow on the lower right). Scroll through the set of apps in the first row to find "Copy Link," the last action option. Then, open your web browser and head to the Kapwing video maker. Paste the URL into the box to import the TikTok video you want to repost on Instagram.

Step 2: Resize for Instagram

Open the Kapwing Studio and upload the TikTok video from your camera roll.

Then, to resize the background, click "Edit Canvas" and change the aspect ratio to square (1:1) or 4:5, the maximum allowed height on Instagram. If you prefer a black background for your Instagram post (to blend in with dark mode), you can also change the background color.

Tap on the TikTok video layer and use the corner sliders to drag the full video into view. Instead of cropping out the top and bottom of the video, you can fit the whole TikTok video in view. Then, position the video where you want it on the screen. You can make the video layer smaller than the canvas to add borders or crop the video in place.

Feel free to explore Kapwing's other editing tools if you want to change the music of your TikTok video, loop it, add a custom thumbnail, or add emoji stickers or text to make a meme. If you don't want the watermarked TikTok outro to appear at the end of the video, click "Trim" to take out the last three seconds.

Step 3: Publish and Share

After the video preview looks right, tap “Publish” to resize it for Instagram. The website will take several seconds to process your video in the cloud, so you won’t have to worry about your computer crashing or freezing. After your video has been processed, you can download the MP4 and publish it directly to Instagram. You can also share the URL of the final video page with your friends.

Alternative: Use the Default Share to Instagram Feature

An alternative method you can use to share on Instagram is to use TikTok's built-in "share to Instagram" feature. To use this, click on the Share arrow and tap the Instagram icon (it's the first action). Then, click to share it on your Feed. Notice that the TikTok watermarks are moved down the video so that they are still visible when Instagram crops the frame to 4:5.

This method is the fastest and easiest way to share a TikTok video on Instagram, but it has the tradeoff of cropping out parts of the video. The resizing method described above has a few more steps but allows you to share the full 9:16 video.
