Video resolution is the number of pixels displayed in each dimension, which is conventionally expressed as width × height. Common options would be 480×360 (360P), 720×480 (480P), 1280×720 (720P), 1920×1080 (1080P), 4096×2160 (4K), etc. Each video file would have a default number for its resolution. However, we can change it for bigger or smaller with some video resolution converter, if you are in such need, like changing the video resolution for being compatible with the device or platform, or changing it to lower its storage for better transferring and sharing, or more. And in this post, we have collected 5 such tools to help you make it easily. Check them now.
Tip: Mostly, we do not recommend users upscale video resolution, since it would lead to video quality loss. The logic is that when we switch video resolution from smaller to bigger, there must require more image information to maintain the original quality, or it would look blurry. However, when an image was created, all of its information is set.
VideoProc can freely turn video resolution into the one you desire without problem. It can upscale video in low-resolution up to 4K, and downscale 4K video to 1080p, 720p or lower to match with all types of upload restrictions placed by different social platforms. When to convert video resolution using VideoProc, owing to its top-notch motion adaptive pixel scaling algorithm, video parameters like bit rate, frame rate, etc. will be converted accordingly, hence VideoProc will assure you the least quality loss to your video clip.

We know that there are a lot of video resolution converters online (free or paid). What they beat the desktop applications is its convenience and requiring no downloading anything. Here what we recommend to you is File-Conversion.
How to Change Video Resolution Online with File-Conversion
Step 1. Open this tool in your browser.
Step 2. Click the Select a File button to import the video clip which you plan to process. It may take a while, depending on the size of your file. And please note that this tool has a harsh limit on the files size. If the file size excesses the number that it allows, there would be a error message and file would not be loaded successfully.
Step 3. Right besides this button, there are a number of format options that you can choose, if you would also like to change its format.
Step 4. Then in the Size option, you can now choose the video resolution that you prefer for your file. What it disappoints us is that it has no customizing option, inputting the width and height numbers that we like. Maybe it can add this feature in the future.
Step 5. Then if you have some requirements on the output quality, you can set it to High or Very High in the Quality feature. Surely, higher quality, longer exporting time.
Step 6. Lastly, just click the Convert button to start processing and exporting all your settings above.
