5 Best Video Resolution Converter for Windows, Mac, and Online

By Cecilia Hwung | Last Update:

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.

1. VideoProc

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.

Here are two pictures (one is from the original video, and the other is from the converted file), and they can tell hardly no difference of quality between them.

Now check how to use VideoProc to change the resolution of a video.

Step 1. Download and install VideoProc on your Windows or Mac computer.

Step 2. Launch VideoProc, and then click the Video button on the launching interface. After entering the video processing panel, click on +Video to import video file(s). When the file is loaded, jump to the lower part of the interface, click on Video tab and choose an output format. Now, you are allowed to change the source video format to another one, or you can keep the original as it is.

Handbrake is a free and open source transcoder for video and audio files for Windows, macOS, and Linux. Most users may apply it as video format changer. However, it actually is video editor with many basic features. With it, you can edit file tile, chapter, and subtitle, add filters with options of deinterlacing, decomb, denoise, detelecine, deblock, grayscale, cropping and scaling, and more.

Step 3. Now you will be in the editing page. Choose Dimensions feature where we can customize the resolution numbers. Now make sure of Anamorphic with None option (we can set it to another, but there are some tiny differences among them. We will tell you in the following.), and then directly input the number that you want into the Width or Height box. If you want change both width and height number but not at the original aspect ratio, please make sure of the Keep Aspect Ratio box unchecking.

In Anamorphic, there are None, Automatic, Loose, and Custom choices.

When choosing None, we can change either Width or Height, since there is the option of Keep Aspect Ratio.

When choosing Automatic, we can change both Width and Height, and no Keep Aspect Ratio option.

When choosing Loose, we can only customize the Width number.

When choosing Custom, we can have two more options of Display Width and PAR. PAR is shot for pixel aspect ratio. So if you also want to change the aspect ratio of a video, this option is recommended.

Step 4. Then just click the Start Encode button to make the conversion.

5. File-Conversion

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.
