When and why should you resize video?

From iPhones to GoPros and to DSLRs to 4K cameras, there are literally hundreds of different ways to capture video content nowadays. The problem this brings, is that it means there’s no standard format across the board. This makes it difficult for those of us needing to play a certain resolution on an incompatible screen or service, especially social media. YouTube, Instagram, Snapchat, and Facebook all require different clip sizes when uploading content, so if you’re wanting to process a 4K, widescreen movies that you’ve just taken on your GoPro cam, and upload it across all your different social media sites, then you’re going to have a bit of a problem on your hands.

Currently, there are only a few default tools built into the operating systems of standard devices that you can use to resize clips. Sure, you can use the Movie Maker app on Windows or iMove on Apple Mac to edit them and add transitions, for example, but with these programs it’s not possible to actually change the video’s dimensions. Of course, there are third-party apps out there that can do the job, but doing so without taking up lots of space on your device, and for free, is pretty much impossible.

Well, that’s where’s Clideo’s Online Video Resizer is unique. Our nifty conversion tool works online so you don’t need to commit to any heavy software downloads, and it also manages to do so without losing quality.

And the best part is: it’ll work on any browsers and across most platforms, whether that’s Windows, Mac, iPhone, or Android. Follow our step-by-step guide below.

  1. Upload your video

    Add a video you want to resize with Clideo

    To start off, select a movie file that you want to reduce the size of from your computer or mobile device by hitting the ‘choose files’ button. You can also resize mp4 video, as well as avi, or mov files. You can even upload your clip via a link from Google Drive, Dropbox or other online service if that works better for you. Once you’ve hit ‘open’ on your desired file, an upload progress bar will keep you uploaded on how long until the upload has been completed.


  2. Resize your video

    Resize your video using a preview

    When the file upload has been completed, your clip will be added to the browser in a new page where you can preview it. From here, you can select an area that you want to crop or resize to using either presets, or by fine-tuning it with the position and zoom selectors. Presets include the correct video dimensions for social media apps: YouTube, Facebook, Instagram, and Snapchat, which can be found under the “Crop options” menu, which relate to the cropping presents 16:9, 9:16, 5:4, 1:1.

    Adjust settings for resizing video

    If you’re resizing a full width landscape video to use on Instagram Stories or Snapchat, for instance, you can opt to give it a black or white background using the buttons on the Background option on the right-hand side of the editor. There are also editing options to reposition or zoom in or out of the moving image within your chosen crop size, if needed.

    When you’re happy with your fresh video size, you can make your changes permanent by simply clicking on the "Resize" button at the bottom right corner of the screen. However, we recommend previewing the movie first by hitting the play button. You also have the option to convert your file via a button on the bottom left. And if you want to save the clip on your Android or iPhone devices, we’d suggest converting it to an MP4 file format for better compatibility. After this, a “processing” screen will appear, and in just a few minutes your new, resized movie will be ready to download back onto your device.

  3. Download the newly-edited video

    Save the resized video to your device

    After the processing screen has done its thing, your new file is ready to be saved. Simply click on the "Download" button to save it to your device. If you prefer, you can save it to Dropbox or Google Drive, or watch it online via the browser preview. And that’s it! Your freshly converted video is ready to be used in whichever way you want.
