Online Video Resizer

Resize video for Instagram, YouTube, Facebook, Twitter and other social media

Social Media Presets

There are prepared presets for all possible post and ad types of Instagram, Facebook, YouTube, Snapchat, Twitter, Pinterest, and LinkedIn.

Custom Video Resizing

If you want your video to be of exact width and height, you can input the values regardless of aspect ratio. The other way is to choose aspect ratio, type in video width and the tool will set video height automatically.

Crop Options

You can fit the whole video into the chosen frame and change the background color, or fill the frame completely in order not to leave the blank space.

Make Vertical Video Horizontal

With Clideo you can convert a vertical video into a horizontal one or vice versa, and blur the background. To do that, choose the necessary preset, click on the "paint bucket" icon and select the Blur option.

Video Conversion

If you choose a social media preset, you'll be able to convert your video to one of the formats supported by the selected social media. If you input custom values, you'll have more than 20 formats to choose from.

How to resize a video online

Step 1

Upload a video

Select a file for resizing from your Mac or Windows computer, iPhone or Android phone, Google Drive or Dropbox account. You can also add a link to a YouTube video or another online resource. The tool lets you edit files up to 500 MB for free.

Step 2

Resize your video file

When the editor opens, select the necessary preset or input custom dimensions. Then choose crop option and adjust the video with zoom and position selectors. Change the background color if needed and specify format for the output file. Click the "Resize" button.

Step 3

Download the resized video

Your output movie is ready to be saved. Now watch the preview to make sure that video hasn't lost quality and click the "Download" button. If you prefer, you can save it back to Dropbox or Google Drive.

We've prepared sizes not only for popular but literally for all social media post and ad types. Among them Instagram Story, IGTV, Youtube 240p - 2160p, Discovery and TrueView Ads, Facebook Cover, In-Stream Ad, and so much more.

If you resized your video so that there are bars left, make them attractive and match with the video itself! For that, you can select one of the suggested colors or the Blur option or input your own color using a hex code.
