How to use the Movavi TikTok video resizer on Windows & Mac

Movavi Video Converter is a robust, user-friendly program that allows users to convert media files and edit them in just a few minutes. Along with the capability to change the aspect ratio and format of your video clips to fit TikTok’s requirements, you can also make video quality adjustments and even apply filters without any other programs or additional steps. It’s a one-stop program to make all of the enhancements you want to your video and then upload it to TikTok. 

To create an effective TikTok video with Movavi Video Converter, you’ll need to crop it to adjust the clip length, ensure that the resolution size is correct, and set the aspect ratio to fit TikTok’s parameters. Below, we’ve included a table of handy references as you resize your TikTok videos. Let’s walk through a few easy steps to get the effect you want.

Step 1. Download and install Movavi Video Converter

First, download the Movavi TikTok video resizer for your Windows PC or Mac. Then, follow the prompts to install the program and launch it on your computer.

Step 2. Import your video files

Click the Add Media button and then Add video to import your video file into Movavi Video Converter. You can also simply drag and drop your video into the program window.

Step 3. Resize your video

To ensure that your project looks right when you upload it to TikTok, start by changing the aspect ratio to 9:16. Click the Edit button and go to the Crop tab. To make the cropping frame vertical, hit the button next to Change the crop orientation. Next, click 9:16 and move the frame to the part of the video you want to crop. Click the Apply button to save changes.

Step 4. Trim your video to the appropriate length

Next, make sure that your video is the right length so that TikTok doesn’t cut off your video before it finishes playing. This shouldn’t be too difficult, as TikTok has extended its maximum video length to 10 minutes. However, keep in mind that most viewers won’t sit through a full 10-minute video. In fact, the recommended length for most TikTok videos is actually around 13–24 seconds, and most video and social media experts strongly recommend keeping videos under three minutes.

Fortunately, Movavi Video Converter makes it easy to trim videos. You can make your video shorter by selecting the Trim tool. Once you’ve clicked on this tool, you can quickly shorten your video. Just position the marker where you want to cut the video and hit the Scissors button. Next, select the unwanted fragment and click the Trash can button.

Step 5. Add video effects

Once your video is the right length and size, have fun exploring Movavi’s features and effects. You can normalize the volume, remove the audio and video noise, adjust the brightness, add video effects, and flip or rotate the video – along with a lot of other cool capabilities that TikTok users love. Once you’ve done editing, click Save and Close.

Step 6. Convert your video to a TikTok format

After you’ve finished cropping and editing your video for TikTok, you’ll need to make sure that it’s saved in the right format to be uploaded to TikTok. To do this, open the Video tab on the bottom side of the program screen. Choose either MP4 or MOV as your file type, and you’ll be ready to save your video to your computer. Click the Convert button to start the process.
