How to change the aspect ratio of your video

During playback, the image may appear stretched, compressed, or bordered by black bars. These deformations occur when the actual horizontal resolution of the monitor or TV's wide screen does not match the width of the video being played.

However, these problems are completely solvable – you just need to convert the aspect ratio! If you are looking for a quick way to do this, then two of our tools will help you, and all you need is an Internet connection and a few minutes in both cases.

Everything else is simple. If you want to add some additional changes after resizing, try our all-in-one video editing tool:

  1. Add your video

    Open Clideo’s Online Video Editor and click "Get started".

  2. Resize the video

    To resize the clip, drag it from the "Uploads" tab to the preview or timeline, then apply a preset in the "Canvas" tab. The most common ones are the 9:16 aspect ratio for vertical screens and 16:9 for horizontal, but you can choose any other preset.

    You can apply either "Fill" or "Fit" options to adjust the video to the new size better. Plus, you can change other settings, like speed, volume, and colors.

    Other than that, you can also add audio to change the sound in the video, as well as add captions.

  3. Download the video

    Check the preview to see if everything looks good. If not, click "Edit" to add changes. Otherwise, download the video to your device or cloud storage.

  6. Crop video with new aspect ratio
  7. When everything's ready, click "Export", wait till the processing ends, and download the result.
