Part 7. FAQs

Is there a free video resizer that supports 500 MB of video?

Yes, tools like Adobe Free Video Resizer and Kapwing Online Video Resizer support large file sizes, often accommodating videos up to 500 MB or more.

How to resize the MP4 video file size?

To resize an MP4 video file size, you can use software like Aiseesoft Video Converter Ultimate. Import the video, select the desired output resolution and output settings, and export the video to the new size.

What is the free software to change the video aspect ratio?

Ezgif Resize Video Online and Kapwing Online Video Resizer offer free options to change the video aspect ratio easily through your web-based platforms.

What is the difference between compression and resizing a video file?

Compression reduces a video file's size by encoding data more efficiently, often resulting in some quality loss but keeping the original resolution. Resizing, however, changes the video's resolution (width and height), directly affecting its dimensions and file size, which can impact visual quality more noticeably.

Does resizing a video reduce quality?

Yes, resizing a video can reduce its quality. A video's sharpness and detail may be lost when it is downscaled due to the resolution decrease. Conversely, upscaling a video to a higher resolution than its original can make it appear blurry or pixelated, as the process interpolates additional pixels, often resulting in a lower-quality image.


Choosing the right video resizer tool depends on your specific needs, whether it's simplicity, a broad range of features, or integration with other design tools. Aiseesoft Video Converter Ultimate, Adobe Free Video Resizer, Ezgif Resize Video Online, Canva Video Resizer, and Kapwing Online Video Resizer each offer unique advantages. After checking the pros and cons, you can select the best tool to do your video resizing jobs quickly and effectively.
