Change Video Resolution Easily on Windows & Mac

There are circumstances that you need to change the video resolutions. For example, when you upload videos from computer to your smartphone or mobile devices, the video resolution needs to decrease to reduce because these devices may support specific resolutions only.

Besides, when uploading videos to online websites, you may encounter the video size and video resolution limitation, for example, you can’t upload 4K video footage to some free online video editors.

While in some cases, you may need to increase the video resolution, for an example, consider the case in which you are trying to burn a video having resolution 320 × 240 to DVD. As the DVD standard needs a high resolution (which should be at least 720 × 480) for every video, you will need to raise the video's resolution (quality) as per needs.

Note: increasing the video resolution will not improve the video quality accordingly, in most cases, only the size will be increased.
